Copper has traditionally been used in home design for its aesthetic qualities of warmth, elegance and unique timeless beauty. Copper and most copper alloys have warmth and elegance compared to the more institutional look of say, stainless steel. Not everyone knows about the tremendous antimicrobial, antibacterial, germicidal power of copper or about copper being a very green material. As more people become aware of these uniquely copper attributes, the demand for copper products will skyrocket. Already the copper industry has been seeing increased demand for copper products over the past eight years, with a large increase in the breadth of copper products as well as the number of copper product manufacturers which supply them. Copper is the only natural material which will kill harmful bacteria, germs, fungus, mold, contagious pathogens and deadly viruses which come in contact with the copper surface. The U.S. EPA has uniquely approved copper as a germicidal agent and numerous studies have proven copper's amazing antibacterial quality. Copper starts killing germs, bacteria, viruses immediately and they are completely eliminated within hours with tremendous health benefits throughout the home, especially kitchens and bathrooms. For example E-Coli survives on stainless steel for up to 34 days while on copper surfaces it is 90% eradicated within 90 minutes, 99.9% within 2 hours and completely within 4 hours.

Copper is also one of the greenest materials ever known to man. Copper can be recycled 100% and in fact most of the copper used today in the U.S. is recycled with 4/5 of the copper ever mined around the world still in use today. Yet, we haven't even come close to tapping into all the copper deposits around the world. Copper is also one of our most durable materials and retains its excellent corrosion resistance, anti-fungal, antimicrobial and weatherability properties throughout it's extremely long life. At the end of it's long life or present application, all the copper can be reclaimed and used again and again somewhere else. Copper besides being the greenest metal is also one of the easiest metals to work with, being very malleable and can be textured, hammered, quilted, patinated, polished, rubbed and fired, giving copper the ability to evolve into many textures, hues, designs and styles, which will fit into any style of home decor, interior design or architecture.

The Mediaplex Complex 22@ in Barcelon, Spain was a highly commended award winner and is comprised of two contrasting main elements. The factory is a horizontal block adjoining a 19th century factory building and is comprised of smooth, opaque, perforated panels of copper. The tower utilizes copper faced screens over it's vertical grid of glazing providing shade. Both architectural elements make extensive use of copper, use copper as a unifying material and share common proportions.

Housing at Frederikskaj Copenhagen, Denmark was a commended award winner and is a residential project of 152 light, airy and spacious owner occupied apartments or condos located directly on the harbor. The architect who see the building akin to a luxury ocean liner docked at port, used materials with a nautical heritage including textured and smooth copper, hardwood windows and glass in a thoroughly modern design. The beautifully detailed but understated copper cladding provides solidity in concert with the concrete frame and blends well into the nearby commercial area.

Copper Architecture Awards

Sun, 22 Aug 2010 16:30:02 GMT

Each year the North American Copper in Architecture Awards acknowledges and spotlights selected North American building projects for innovative and exceptional use of architectural copper. The architectural copper awards program highlights a wide scope of projects which highlight craftsmanship, attention to detail, and architectural vision. Copper has historically long been used for its great natural beauty and finish, it's durability and performance, copper's long service life and recyclability. Copper is still today a superior building material and also one of most eco-friendly and green building materials, which is being utilized and adapted for an ever wider variety of contemporary and cutting edge building and architectural applications. Three of the twelve copper in architecture award winners are described and shown below.

The Waipolu Gallery above uses copper wall cladding and copper roofing which were chosen for this project as copper will perform well over a very long time and with very little maintenance in a very corrosive ocean side location. Copper's beauty and fluidity compliment the modern art contained within the structure. The copper provides a softer contrast to the other more linear materials used. Excellent workability or malleability of copper was advantageous allowing easy re-working or shaping on site. The building architects also like there will be changes in copper's patina or color over time, producing an ever evolving work of art. The studio with it's stainless steel, glass and concrete linear space is joined by a floating glass bridge to the copper clad gallery. The glass bridge rises above a limestone staircase which connects the building's three levels.

The Mark Olsen Project exhibits excellent old world craftsmanship, with a copper roof and other architectural copper features such as copper finials, copper gutters and ornamental downspouts with copper conductor heads, copper crown molding, fascia and soffit, copper chimney top shroud and extended copper window box. This stately home has exquisite detailing and exudes quiet elegance from it's naturally weathered copper features. 16,000 pounds worth of hand crafted architectural copper work are used for this home's architecture. The copper roof is comprised of diamond shaped interlocking copper shingles, copper ridge vents and flashing. Of note, no sealants were used, only traditional craftsmanship and installation techniques were employed along with some soldering work on the copper gutters providing very long term durability with little to no maintenance required.

One hundred fifty years in the making, the Cathedral of St. John the Baptist in Charleston, South Carolina has at long last been restored after being completely destroyed by fire in 1861. A soaring neo-gothic style copper spire, which had long been planned, was finally realized this past spring. The stunning beauty of the copper spire with it's gold leaf finished copper cross can be seen across the Charleston skyline and out to Sullivan Island. The cathedral's tower was finished with a stone veneer and at it's top there are four copper clad archways with copper torch finials. The copper spire with gold-leaf copper cross finial is perched on top at center of the copper arches. The 200 square feet of gold leaf which covers the cross will last at least 40 years without touch-up while the crowning copper art work comprised of arches, finials, spire and cross at the peak of the cathedral will last and stay beautiful for generations to come.

Green Building Materials - Copper - Natural Stone

Fri, 23 Jul 2010 13:06:54 GMT

Copper and natural stone make ideal green building materials for both the exterior and interior of all buildings, including commercial, public and residential buildings. What is green building? Simply put green building means the construction, renovation or remodeling of houses, public and commercial buildings so they are more durable, environmentally responsible, energy efficient and healthier for their occupants throughout the building's lifespan or life cycle. This is basically accomplished by designing and constructing buildings that last a long time, are more efficient, use less energy and water and are healthier spaces to occupy and live in. Historically, well designed and constructed buildings have delivered short term goals of utility, economy, durability and comfort. Green building really just takes the next step in building even better homes, commercial and public buildings by improving on their long term durability, quality, efficiency, high performance, human health, environmental impact, life cycle cost and sustainability. A building's total life cycle cost includes it's design, siting, construction, operation, maintenance, repairs, replacements, renovation, deconstruction, salvage, disposal and recycling. Green building materials typically include: renewable plant materials such as quick growing straw, bamboo and wood from sustainably managed forests; materials which are non-toxic, reusable and recyclable such as dimension natural stone, recycled stone and recyclable metals. Eliminating construction materials and interior finishes which have emissions of toxic gases such as formaldehyde and VOC's improve a building's indoor air quality and is healthier for occupants. Moisture control and eliminating biological or organic sources of mold, bacteria, fungi and pathogens will also promote healthier air and living space. Implementing green building techniques reduces negative impact on human health and the environment during multiple phases including the production of building materials, building construction, occupation, building operation and maintenance of a green design building. While many green buildings cost a premium which averages just less than two percent initially, green building will typically yield a financial return or savings of over ten times that initial premium during the life of the building. Green building simply saves money, protects the environment and provides healthier living spaces. The strong case for green building is abundantly clear considering the positive impact on human health, our environment and our finances.

Copper Mining Quarry and Natural Stone Quarry

Natural resources such as copper and natural stone are mined or quarried and minimally processed natural materials as opposed to artificially manufactured materials, faux or simulated materials. Pure copper and natural stone share many green building material qualities: they are mined or quarried directly from the earth and minimally processed using environmentally conscious techniques; all waste material can be used or recycled; they require no external finishes or chemical treatments; they generate no harmful emissions or byproducts; they do not promote growth of mold, germs or other harmful pathogens; they are healthy, hygienic and non-toxic; they promote more even indoor temperature and healthier indoor air quality; they are moisture and corrosion resistant; they weather extremely well naturally; they are not flammable materials; they are not damaged by water; they do not break down, decompose, decay or deteriorate like previously living organic materials and most man made materials; they age beautifully and gracefully as natural patina formation, discoloration, pitting, dents or cracks enhance character and natural appearance; they require little upkeep or maintenance; they are extremely durable, outlasting the owner's lifetime and the building's lifespan; they are salvageable, reusable, absolutely recyclable and retain their value extremely well. Copper and natural stone are two of the oldest, most durable building materials used by mankind and countless buildings and structures incorporating natural stone and copper architecture stood for centuries. Copper and natural stone were used because they were abundant resources found directly in the natural environment, required minimal processing and were fairly easy to work with. Today spending even a little more for natural, earth friendly, durable materials has proven cheaper in the long run because they won’t have to be replaced as often, maintained as much and can be recycled. Considering on building materials life-cycle cost, rather than focusing solely on initial cost can yield some eye opening results.

LEED Gold Penn State SALA and City Center LEED Gold in Las Vegas

We spotlighted the Penn State Sala building above in a previous blog for it's heavy use of copper (over 80,000 pounds) helping it achieve it's U.S. Green Building Council Gold LEED certification and remarkably at no additional cost over conventional building. The recent City center in Las Vegas also received LEED Gold certification by the U.S. Green Building Council for six of it's buildings, including Aria, Vdara, Crystals, Mandarin Oriental, Las Vegas and Veer Towers. That made City Center one of the largest sustainable green building developments in the entire world. The immense project entailed collaborative involvement by eight renowned architecture firms. Green building material selection, included extensive use of natural stone for interior spaces and exteriors of the buildings. While other green materials were considered, natural stone provided the architecture with a natural textured, tactile feel and the richness, warmth, comfort, earthy look and colors they sought. The Aria building encompasses 70,000 square feet of natural quartzite stone cladding in a varying thickness mosaic pattern on it's exterior walls. Inside the buildings, different uses of natural stone were employed including a mosaic stone, stacked stone, flat honed or polished stone, to provide contrasting looks and changes in texture. Everyone involved with the project was happy with the results and the buildings continue to garner positive feedback and compliments. See additional pictures of City Center and information on it's green building features in the Stone World article Stone Contributes to LEED Certification for New Las Vegas Landmark

Architectural Copper Work and Natural Stone Wall Masonry

View additional natural stone pictures of genuine natural stone installations at the Rutland Minstone website, encompassing natural stone tile flooring, natural stone walls, natural stone patios, garden stone paving, landscaping, slate roofs and stone columns. Slate, travertine, quartzite, limestone, sandstone and flagstone tiles, wall veneer panels and pavers are some of the featured natural stone applications. With large advances in mining, processing and shipping technology, use of natural stone has grown from use primarily only in major buildings and large expensive estates to becoming a staple in homes and buildings of every size and budget today. There has been a drastic reduction of genuine stone prices over the last decade or so. Around the world there is now an enormous inventory of natural stone and even more is being discovered every day. A combination of many technological advances and this very plentiful supply have combined to make natural stone very affordable and price competitive with man made materials, while having better green building characteristics and life cycle cost benefits. People have embraced the beauty and elegance of this unique, all natural material for their floors, wall coverings, kitchens, baths, outdoor landscaping and paving. Consumers prefer natural stone because it is the real thing which can not be duplicated in a laboratory or factory but is nature's very own genuine product. Natural stone is created by nature in many thousands of color variations with no two natural stone pieces exactly the same. Nothing approaches the uniqueness, durability, wide applicability of genuine natural stone and pure copper. From the beginning of time to far into the future, copper and natural stone have always been excellent green building materials while having natural beauty, grace, warm richness and timeless elegance.

Green Home - Copper Building

Fri, 11 Dec 2009 17:33:24 GMT

Green, green home, green building, going green, sustainability and LEED are all catch phrases that seem to be catching steam and quickly building momentum these days. What does go green and green building specifically mean? Green building is the philosophy, design and implementation of the most efficient use of resources, that are both environmentally responsible and positively affect our health throughout the building's entire life cycle. The building's life cycle starts with siting, includes design, construction, operation, maintenance, renovation and then finally demolition. The total long term environmental cost of all building components is calculated and factors into green building design. Green building extends traditional building's short term concerns of economy, utility, durability and comfort with long term goals of sustainability, high performance, human health and environmental impact. The environment is impacted by the production and consumption of materials, natural resources, energy, water and land. Our environment is adversely altered by the building's inhabitants generation of waste products, water pollution, air pollution, heat and noise. Ultimate effects may include harm to human health, degradation of the environment including the atmosphere and loss of natural resources. Green building's goal is to reduce or eliminate any adverse health and environmental impact for every kind of building including residential, public, governmental, religious and commercial.

Copper Mining

The whole field of green building is literally exploding and there is so much information already available out there on many of the aspects involved with green building. Today's blog is just an overview that defines what green building is and there will be a subsequent series of articles that will cover in more depth the many aspects involved. We will also closely examine and feature the role of copper in green building and green homes. Copper homes, copper building and copper architecture play an important part in virtually all green building designs, including some or all of the following: plumbing, wiring, solar panels, windmills, tankless water heaters, external wall siding, roofing, guttering, roof structures, flashing, chimneys, fascia, vents, duct work, healthier copper kitchen designs, even outside door and window cladding. Copper usage in fact can contribute upwards of 13 points in various areas towards LEED green building certification.

Copper Duct Work Can Improve IAQ

Wed, 21 Oct 2009 13:12:39 GMT

Ductwork in commercial and residential forced air heating and air conditioning systems circulate air throughout your building in the process of heating and cooling. Any biological pollutants, contaminants, pathogens, bacteria, microbes and viruses present in the air circulating around the HVAC system are breathed in and also settle on surfaces in all the rooms. Exasperating this problem in newer buildings is the fact that most are constructed to be more sealed or tighter for energy efficiency which in turn reduces fresh air exchange or ventilation. The same pollutants and disease causing organisms become concentrated and readily multiply. Also typically air duct work is a friendly, hospitable place for fungi, bacteria and mold to grow and spread. Like most living organisms, they require temperatures between 40-120 degrees F, food and moisture, conditions which are present in commercial and residential heating and A/C duct work. This can result in poor IAQ or indoor air quality, some times referred to as sick building syndrome, not only having possibility of making us sick but understandably promoting allergic reactions and exasperating asthma conditions.

To reduce our exposure to such biological pollutants and contaminants at home, at work and in public places, we need to attack this increasing problem on several fronts. Increasing or providing adequate fresh air ventilation can help reduce the concentration and trapping of these bacteria and pollutants. Reducing humidity or moisture levels to less than 50% or even 30% will help prevent condensation and disrupt growth of microbes, bacteria and mold. Of course reducing the sources of biological pollutants and even destroying or eliminating those present is paramount. Methods tried to reduce and eliminate circulating biological pollutants include cleaning of air ducts and decontamination of air ducts using chemicals, biocides, fungicides and ozone. Unfortunately duct work cleaning has not been proven to be effective. The EPA (Environmental Protection Agency) in fact not only has stated that air duct cleaning has never been shown to actually prevent health problems but EPA also does not recommend that air ducts be cleaned except on a as needed basis. Regarding decontaminating heating and A/C systems including duct work, the EPA has stated that there is an unresolved controversy over the necessity and wisdom of introducing chemical biocides and ozone into duct work. The American Conference of Governmental Industrial Hygienists made an even stronger statement saying that application of chemical biocides as opposed to removing microbial growth and settled biological material is considered unacceptable. Still the fact remains that unhealthy biological pollutants and microbial growth are circulating around and residing in our duct work and it is imperative that something be done to reduce and eliminate it.

Beyond increasing fresh air ventilation and reducing moisture or humidity levels to help control biological pollutants and growth, there is considerable growing interest in deploying copper material for use as duct work. Copper has already been well documented and proven to destroy harmful bacteria, germs, microbes, pathogens, molds, fungi and viruses which come in contact with copper surfaces. Copper is also EPA approved as an antimicrobial agent after exhaustive tests confirmed it's effectiveness. Plus copper is inherently much safer than widespread use of ozone and chemical biocides - germicides whether liquids, sprays or aerosols. Copper and strong copper alloy materials are already proving effective in reducing the existence of biological pollutants, biological growths and bioaerosol contaminants in A/C duct work. Copper is quite an order of magnitude better than materials historically and commonly used for duct work such as galvanized steel, aluminum and stainless steel. While copper will not cure all IAQ problems and continuing studies will quantify it's measurable improvement in indoor air quality, it is known that usage of copper duct work will improve IAQ and is a positive step in the right direction. While we are waiting on definitive EPA approval for performance and health claims of copper duct work, builders and remodelers might also consider copper for it's elegance, beauty, richness, longevity, durability and corrosion resistance which are all much greater than any other material. Not coincidentally, these are the same reasons we have seen copper's ageless popularity for use in building architectural features and also increasingly in copper kitchens and copper home decor.

Architectural Restoration - Historic Preservation with Copper

Mon, 31 Aug 2009 15:18:56 GMT

There are many older buildings with very distinctive architectural features which after a length of time those features may deteriorate, crack, crumble or corrode. For architectural, historical and preservation reasons these worn out building features, when repairs are not feasible, are frequently restored with replacements maintaining an acceptable likeness in form, texture and color and possessing a long lifespan. Being ecologically green, sustainable, low maintenance, with excellent weather-ability and having low total environmental cost are all very positive objectives to observe in architectural restoration or historic preservation. Copper has historically been commonly used for architectural building features for it's elegance, durability, weather-ability, long life and pleasing earth tone patina. Copper's character allows it to suitably replace not only original copper work but also original cast iron, lead, other metals and virtually all types of masonry including stone, terra cotta, etc. Copper will naturally develop a protective patina cycling through shades from raw copper's salmon color to various browns to bluish greens then finally to a grayish light green over the course of the many decades or centuries of it's long life. Copper can be painted any color, or coated to maintain it's original color or even pre-patinated to a dark brown or it's final light green color. It is best environmentally to avoid any paints, coatings and chemicals and just allow nature to run it's course with it's own pleasing array of changing colors. Following are before and after pictures of some of the architectural restorations which have been performed by Rutland's Architectural Copper Work shop using pure copper replacement material.

Galvanic Corrosion of Dissimilar Metals

Thu, 06 Aug 2009 17:35:19 GMT

Galvanic Corrosion is an electrochemical process which occurs when dissimilar metals are in contact with each other in the presence of an electrolyte, most commonly being moisture and oxygen. For example rain water and salt water make especially good electrolytes. An electrolyte could be any non-metal matter that will conduct an electric current and are predominantly liquids or moisture. Every metal has been rated for nobility and then placed on galvanic scales according to nobility. Basically nobility is a measurement of the resistance to corrosion, especially of one metal contacting another metal. Metals that are the least noble means they are very anodic, electropositive or high potential and will corrode most easily. Whereas metals that are the most noble, means they are highly cathodic, electronegative or low potential and will be the most resistant to corrosion. The most corrosive effects will occur between metals from the opposite ends of the galvanic scale or ranking of nobility. This difference in electrical potential between two or more metals causes galvanic corrosion. Dissimilar metals in contact with each other in the presence of an electrolyte causes current to flow through their points of contact at the expense of the metal with the higher potential or less nobility. The much less noble metal is gradually consumed in the Electro-chemical reaction and will deteriorate or wear away as the metal ions migrate away from the very anodic metal to the more noble cathodic one. The more noble metal's corrosion resistance actually increases from this transfer of ions to it from the less noble metal, while the other metal is gradually getting consumed. Below is an abbreviated galvanic scale showing ranking of the most common construction metals from the least noble up to the most noble in a normal construction setting where both moisture and oxygen are present.

Galvanic Scale (Nobility of Common Metals)*
Least Noble
Aluminum
Zinc
Galvanized Steel
Iron
Stainless Steel – Active
Tin
Lead
Brass, Bronze
Copper
Stainless Steel – Passive
Titanium
Most Noble

Electropotential of Various Metals
High
Aluminum     +1.30
Zinc            +0.76
Chromium     +0.60
Iron            +0.44
Nickel        +0.22
Tin              +0.13
Lead            +0.12
Copper         -0.34
Silver           -0.80
Platinum       -0.86
Gold            -1.10
Low

Since dissimilar metals in contact with each other in the presence of oxygen and moisture will result in the less noble metal being corroded or eaten away the more noble one, contact between dissimilar metals should be avoided. For example, copper as one of the most noble of metals should be kept separated from less noble metal such as aluminum and galvanized steel. If contact between dissimilar metals cannot be avoided, their surfaces should be insulated as much as possible at the least with a non-metallic, non-conductive coating, such as bituminous or zinc chromate primers or paint. Separating the dissimilar metals with tape, gaskets, waterproof membrane, sealants or other non-conductive material that does not absorb and hold moisture can be used effectively. Care must also be taken to avoid the liquid wash run off or discharge from the drains from noble metals to less noble ones. For example rain water run off from a copper roof going into aluminum gutters and downspouts will result in traces of copper salts in the run off wash accelerating corrosion of the aluminum. Additionally, the use of galvanized nails, screws, flashing or drip edge on copper roofing or copper gutters should likewise be avoided as such less noble fasteners and metals will corrode rapidly. While rain water is a good electrolyte so too is high humidity or moisture laden air especially when it contains a high concentration of corrosive acids as is typically found in larger cities or near industry. In industrial or heavily populated areas, harmful electrolytes are formed by the absorption of gases by rain and fog to form acids and salts, while in coastal areas a saline electrolyte is formed by the combination of salt with the moisture laden air.

As copper has one of the highest galvanic numbers or nobility of construction metals, copper will not be harmed by contact with any of the common metals. However, copper will promote corrosion of other less noble metals if placed in direct contact with them. Copper can be used most appropriately with lead, tin, lead-tin solder or stainless steel under almost any circumstance. The primary metals of concern in terms of galvanic corrosion contact with copper are aluminum and zinc. Large differences in the thermal expansion rate between copper and these metals may cause additional problems. Also avoid using copper and some brass fasteners with aluminum, zinc and most ferrous metal. Paints or coatings that are used for isolation must be compatible with both of the dissimilar metals. The bituminous or zinc chromate primers and paints can be used between copper and aluminum surfaces. These same coatings or a red lead primer can also be effective in separating copper from iron and the other ferrous metals such as galvanized steel or mild steels.

Another type of corrosion called erosion corrosion is caused by the flow of acidic water concentrated into a very small area. While especially true for the least noble and most corrosive of metals, but capable of affecting all metals, acidic water allowed to concentrate on a small area, for example rain water from a large area like a roof diverted towards a flashing, valley or gutter can cause erosion corrosion. Also acidic water or liquids pooling on metal surfaces or trapped without air circulation between roofing or sheathing can quickly corrode the metal. Solution is to eliminate such pooling, maintain air circulation underneath metal roofs or between inert roofing material and drip edge, valleys and flashing. Another solution is to use replaceable reinforcing insulative strips between the inert materials and metal. Raw zinc and aluminum especially are susceptible to prolonged contact with acidic moisture, as for example the underside of a zinc roof. But care should be taken even with copper and stainless steel. Copper and zinc possess a superior property in that both will gradually develop a long term protective patina that helps guard against such corrosive effects for a very long period of time providing initial safeguards are exercised such as drying out provisions or temporary coatings.

Example of the protective patina that formed on these copper dome roofs

*Note: Galvanic chart rankings involving sea water immersion and low oxygen conditions will vary somewhat - the more typical nobility given here is for land based construction.

Gutter Garden - Copper Gutter Garden

Tue, 02 Jun 2009 17:54:57 GMT

Gutter gardens are receiving much buzz over the internet and are a good approach to generating fresh produce or a colorful display of flowers around your home. A gutter garden is especially ideal when space is at a premium or if you wish to have a tidy and more ergonomic gardening setup. Nothing is better tasting and more satisfying than freshly picked produce for that awesome salad, fresh salsa and a plethora of other healthy vegetable dishes. Gutter gardens are essentially akin to planters that hang from your house at a convenient height and are typically fashioned using some form of home guttering to serve as your planter. This article discusses and compares several types of commercially available gutters that are good options for use in a gutter garden. Then we will explain exactly which components you will need and how to assemble your very own gutter garden. I do not know who first came up with the idea for a gutter garden, probably someone a long time ago and it was never publicized. Now with power of the Internet word gets around. I did find an article from Martha Stewart Living dating March 2006 that called them "Garden Pots" and they used copper gutters stacked in several tiers to form their gutter garden. They were growing hanging ivy in them to form a living screen off of a porch, but could just as easily be growing flowers or produce in them. Hanging your gutter garden as they did with chains is another option to mounting on a wall, just make sure your chains, anchors and supports are all robust and secure.

From Martha Stewart Living - March 2006
"Surprising Garden Pots: Copper Gutters"

Re-using old guttering or buying cheap aluminum or plastic guttering are tempting options but may perhaps not be the best option. It is recommended you stay away from any kind of painted, rusted guttering or lead coated guttering for obvious health reasons if you are growing produce. Many plastics have unhealthy emissions and plastic gutters can also break down from the weight, UV sunlight and trowel work. It is best to use a gutter made from a pure metal that does not have any chemicals or paint applied, does not corrode or rust over time, is durable, long lasting, naturally weathers well, is aesthetically pleasing and is a genuinely attractive feature of your home. Steel and aluminum are relatively low priced but most varieties require some type of coating to resist rust and corrosion and coatings oxidize, scratch, are not durable, long lasting and mostly unhealthy too for a gutter garden. Galvalume is a zinc-aluminum coated steel that is a better candidate than either steel or aluminum alone, combining the corrosion and rust resistance of zinc and aluminum with the strength of steel but with an industrial looking gray metallic appearance and you would probably be tempted to paint this material. Three even better choices for your gutter garden are zinc, stainless steel and copper. Everyone is familiar with the appearance and attributes of stainless steel and it is a viable option. Stainless steel does not rust providing it's surface is not damaged and it is generally considered a healthy, sanitary material. Stainless steel's shiny appearance may be attractive or it may not blend in or complement your home's exterior. Pure zinc is a viable, healthy option that is durable, weathers well and zinc develops an attractive protective, grey patina that is somewhat pewter like though zinc is priced higher than galvalume and stainless steel. Then we have pure copper which may be the best choice for a multitude of reasons: copper has proven itself for centuries to be the most durable and longest lasting metal; copper weathers extremely well, forming a protective attractive patina; requires little to no maintenance; copper is attractive, aesthetically pleasing, elegant and complements most home decor well; copper is EPA approved antimicrobial, germicidal, antibacterial and fungicidal; copper is a key nutrient for plant life; copper is considered eco-friendly and is a green building material. These are all attractive and most desirable traits for use in your gutter garden. Copper although being our highest rated choice also has the highest initial cost of all the metals and metal alloys mentioned above. Copper's many and unique advantages, help justify it's premium cost, especially considering the relatively short lengths required for most gutter gardens, which put copper gutters' premium price within reach and affordability.

Once you have decided on the material for your gutter, you will then likely choose between three common styles of gutter: K-style gutter, half-round gutter and box gutter. A box gutter will give you the most volume with which to garden with, and as it's name suggests, it has a rectangular box appearance or if you like a plain box planter. K-style gutters are probably the most common residential gutters used in the U.S. and are somewhat boxy as well, though with a angled stepped front for a little more pizzazz. Half round gutters do look just like they sound, like half of a round cylinder or pipe and half-round gutters also have the most elegant appearance of all the various gutter types. There are also quarter round gutters which also are very attractive with their curved front. Quarter round and K-style gutters are generally available from 5 inches to 8 inches wide, half round gutters usually from 5 inches to 10 inches wide and box gutters are usually manufactured to size. Custom widths are also available through Rutland Gutter Supply. Compare the different appearances of K-style, box gutters, half-round, quarter round and embossed gutters, all pictured below.

In addition to choosing the material and style of gutter for your gutter garden, you will also choose the type of gutter hangers you will use to hang your gutter garden and the end caps used to cap off and finish the two ends of your gutter garden. There are several styles or types of gutter hangers available. So-called hidden gutter hangers are very commonly used and are called hidden because they are mostly not seen from the ground in a roof gutter system. Hidden hangers may not be the best choice for your gutter garden since they are positioned across the top of your gutter, they may obstruct or at least inconvenience your gardening work. A fascia mounting, squared-off gutter hanger with a front lip as pictured below may be better for box and K-style gutters while one of the decorative gutter hangers pictured below would prove ideal for the rounded gutters. A gutter spring clip holds the gutter in place when resting on a decorative gutter hanger and works well should you wish to remove the gutter easily for any kind of maintenance in another spot. You would use a gutter hanger every few feet to hold up the weight of your gutter garden, generally every three feet at least or every 2 feet if you also happen to live in the snow belt. You will also need to use so-called gutter hanger wedges, if your home's walls have an angled slope, to keep the gutter garden aligned perpendicular. Gutter hanger wedges are available in several sizes to address a variety of slopes in your home's siding or fascia. Installers typically use nails or screws to fasten gutter hangers and gutters to your home's wall or fascia. I would recommend a screw's added holding power recognizing a gutter garden's weight. Your choice of gutter end caps include flat end caps for all the various styles of gutters or also available for the half round guttering are radius end caps, which give your gutter garden ends an attractive and graceful rounded appearance. The gutter end caps are attached by both riveting and soldering them to the gutter. If choosing copper guttering for your gutter garden, it is recommended you use all copper materials for the guttering, gutter end caps, copper rivets, gutter hangers, hanger wedges and bronze or stainless steel screws. This is to maintain a uniform matching appearance and avoid corrosive effect of dissimilar metals. Below are pictures of various types of gutter hangers, gutter end caps, gutter spring clips and gutter hanger wedges.

After you have decided on the exact style and material for your gutter garden components, measure the exact lengths of guttering you need and keep in mind that you can go with a double or triple decker design if you desire. Your gutter garden should be in a location where it will receive the amount of sunshine recommended for what ever you are planning to grow. After the components have been ordered and they have been delivered, you are ready to attach the guttering for your gutter garden to your house. Measure and mark off the locations for your gutter hangers, to keep them evenly spaced and horizontally level. If using hidden hangers place them evenly spaced across the top of the guttering and attach to the wall with screws and use wedges if necessary. If using a squared-off box hanger or the decorative rounded hangers, attach the gutter hangers to the house siding with screws using appropriate sloped wedges if necessary, lay your gutter on the hangers and attach the hanger spring clips between the gutter hanger and guttering. Now you are done and can fill up your gutter garden with gardening soil or some composite mixture of garden soil, peat moss, manure, fertilizer and moisture retaining granules. Plant your seeds, seedlings or plants, water and enjoy your garden!

Additional Tips:
Avoid applying any chemicals or paint to the inside of your gutter garden for healthier plants and produce. If you absolutely must paint to achieve a desired color match, then do so only on the outside surface. Stainless steel will need to be cleaned and polished occasionally to keep it's appearance while zinc and copper weather naturally and keep their beautiful, elegant appearance throughout their lifespan. Copper can be waxed regularly or even coated with a clearcoat or lacquer if you wish to keep the shiny new copper appearance but again do not apply any coating to the inside to avoid chemicals and to take full advantage of copper's natural germicidal, antimicrobial and fungicidal properties. Also any wax or coating is temporary and needs to be re-applied. The natural copper patina however needs little to no maintenance When copper weathers there is a natural patina that forms on it's surface which serves as a protective coating and the patina does not affect copper's antibacterial properties. The copper patina changes color with age, progressing from a shiny salmon color, to reddish shades of brown, brown, greenish brown and finally a light green pastel color. The outside patination process can also be accelerated if desired by applying selective accelerants. Copper is revered and prized for it's graceful, elegant appearance and gradually changing color throughout it's very long lifespan. Approximate copper weathering color chart is illustrated below. If you desire drainage for your gutter garden, you may either choose to drill a few small holes sparsely across the entire length or have your guttering fabricated with rain chain style taps every few feet along the length.

Copper Dome Construction

Wed, 27 May 2009 17:41:54 GMT

Today's blog will take a simplified look at custom copper dome construction. Copper domes are typically constructed with the surface consisting of some variety of either copper tile or copper panels. For this example we will be using copper tile for our custom copper dome roof. Copper roof tile can be purchased from a manufacturer and in this particular case we will be using hand-made copper tile, hand-cut from copper sheets. Diamond shaped hand made, hand cut, interlocking copper tile are shown below - there are approximately 136 per square (100 sq ft).

For the framework we will be using aluminum tubing, plywood sheathing and waterproof membrane. We begin by precisely cutting square aluminum tubing to size and bending the tubes using a roll forming machine to form the base and the many vertical support cross members. A partially completed aluminum frame is shown below.

After all the aluminum framing tubes have been fully welded together, we then cut plywood sheathing panels to size, to fit precisely between the aluminum cross members and stretch from base to top. We affix them to the aluminum vertical support framework. See partially completed plywood sheathing work below.

After all the plywood sheathing panels have been securely fastened in place with self-tapping screws, we then apply to the partially completed dome a self-sealing waterproof membrane, taking care to completely seal the dome. After the membrane is in place, we draw guidelines and begin carefully attaching the hand-cut copper tile to the dome and to each other. The copper tile have been designed to interlock securely with each other and we use copper ring shank nails to fasten them to the plywood.

Now this copper dome project is nearly completed as we attach the last of the copper tile to the very top of the copper dome roof. When all the copper tile have finally been attached, we are ready to crown the top of the copper dome with a copper finial. Copper finials come in a multitude of shapes, sizes and designs. They can be simple like the first photo below or more elaborate as in the 2nd picture below.

Although this project may have been over simplified here, it was actually extremely labor intensive, benefiting from knowledgeable construction and metal fabrication expertise. Copper dome construction is very precise work and it can be very exacting just keeping each copper tile perfectly lined up straight and in perfect alignment with each other. All pictures provided herein and this copper dome project very beautifully accomplished by the skilled team at Rutland Copper Gutter Supply & Architectural Copper Work

Copper Leader Head Restoration Project

Thu, 21 May 2009 17:53:33 GMT

The custom copper leader head (also known as conductor head, hopper head, rain collector box) in video below is a recreation of a cast iron leader head that adorned a church in England for centuries. Rutland Gutter Supply specializes in the highest quality of custom architectural copper work and copper gutter systems. There are over sixty-five different leader head designs now in Rutland's growing collection. View some of these custom copper leader heads and other custom copperwork, such as copper domes, copper cupolas, copper finials, copper chimney caps, copper spires, copper gutters, etc at Rutland Gutter Supply & Architectural Copper Work. Leader heads are mounted inline on the downspouts being fed from a building's gutters. Leader heads mix air in with the water flowing down through the downspouts, eliminating the back pressure or vacuum. See picture below of an installed copper leader head and copper guttering.

Custom leader heads are typically manufactured from pure copper, zinc, mill finish aluminum or lead coated copper on the finest commercial and residential gutter systems. Copper guttering and copper leader heads particularly, can last 80-100 years, require little to no maintenance, are aesthetically pleasing, they can be recycled nearly 100% and contribute to green building objectives. Leader heads add both a decorative (as seen in picture) and functional touch. Watch video below of a custom leader head that has been recreated from a centuries old one.

Copper - EPA Approved As Antimicrobial Agent

Tue, 05 May 2009 15:56:16 GMT

With a solid body of evidence showing copper's broad spectrum of antimicrobial efficacy and copper's ability to inhibit the most important pathogens challenging public health today, including MRSA, Clostridium difficile, Escherichia coli (E.coli), Legionella pneumophila (Legionnaire's disease bactera) and Influenza A viruses. Clinical trials examining copper's antimicrobial potential and role in fighting pathogens, transmissions of germs and Influenza A viruses such the bird flu and swine flu epidemics are being undertaken in the U.S., U.K., Germany, Japan and South Africa.

The EPA, the U.S. Environmental Protection Agency, has approved the registration of copper as an antimicrobial agent to reduce harmful bacteria linked to potentially deadly microbial infections, following a year of comprehensive testing in an independent US laboratory. The tests showed that 99.9% of bacteria on a copper surface were eliminated within 2 hours of exposure. Typically this type of registration has previously been granted to liquids and gases falling under the sanitizer and disinfectant categories. Copper's mechanical and aesthetic properties makes it an ideal choice for use in all products or surfaces offering us the benefits of copper's antimicrobial power.

A concise reference article to download is "Copper: essential for life" and a reference website page entitled "Antimicrobial Copper". Increased use of copper is indicated not just for commercial or public buildings and outside public fixtures but in the home copper's logical uses are plentiful including the bathrooms and in a copper kitchen. You can enjoy copper's aesthetic appearance throughout your home, while enjoying copper's natural health benefits with it's proven germicidal, antibacterial and antimicrobial power.

Copper Effective At Stopping Spread of Germs

Sun, 03 May 2009 16:44:13 GMT

The need to prevent the spread of germs has always been a major concern. Research indicates that a copper surface is more effective at preventing the spread of germs than stainless steel. Copper has a 2000 year history of antimicrobial applications in a multitude of cultures. More recent research has sought to determine uncoated copper's effectiveness in stemming the proliferation of infectious disease. At the University of Southampton in the U.K. research studies have shown that many common disease causing microbes such as E. coli, Aspergillus niger (black mold) and Influenza A, die within hours on copper surfaces. The Influenza A family of viruses includes the problematic Avian flu and swine flu strains and copper can help contain a flu. Even deadly antibiotic resistant bacteria associated with infections such as MRSA (Methicillin Resistant Staphylococcus Aureus) die within 1.5 hours on pure copper. On stainless steel and plastics, typically used for food-processing hardware, pathogens survived unabated for days, sometimes more than 30 days. There is enough solid evidence to put man’s oldest metal to work throughout the world to help protect us from infectious disease. Tested copper alloys, such as brass or bronze also offer increased protection over non-copper containing materials such as stainless steel, painted surfaces, wood and plastics, although not nearly as effective as pure copper surfaces.

Some fairly common and obvious uses in the home for elegant yet functional copper home decor include copper kitchen sinks, bathroom copper sinks, copper bar sinks, food prep sinks, copper basin, copper vanity sink, copper door knobs, copper handles, copper range hoods, copper planters, copper pot racks, copper bowls, copper sheets or copper tiles for making copper countertops and copper sink backsplashes, copper tabletops, copper chair arms, copper wall plates and switches, copper light canopies, copper ceiling fans, copper vents, copper louvers, copper cookware, etc. There are germ killing copper facades available for refrigerators, dishwashers, freezers, ice-makers, ovens and ranges. There are copper-plated kitchen appliances, copper vases, copper sculpture, copper accent pieces, copper planters, even copper flowers. Copper bathroom fixtures and copper kitchen appointments may be the most obvious places to most benefit from and utilize copper's antimicrobial power, yet manufacturers are now focusing in on all home furnishings and furniture as well as laptop, remote control and cell phone cases. The ceiling for new copper surfaced products is sky high, especially considering copper's aesthetic qualities, durability, long lifespan and green copper work as eco-friendly too.
