Autumn River
www.autumnriver.biz
September 2005
In a new application for an old material, Autumn River is using silica gel —the material commonly found in shoe boxes labeled “Do Not Eat”—to remove moisture from within building cavities, thereby eliminating the conditions required for mold growth.

The Desiccant Strip is a 61ž2' length of spun polyethylene material formed into pouches containing engineered silica gel. The strip has been designed to guarantee that upon installation, moisture levels within a building cavity are rapidly brought below the point where mold and other decay agents can function. Once the strip has absorbed moisture it will not release the moisture back into the wall cavity until the relative humidity within the cavity has been reduced dramatically and stays down. Independent testing has proven that the strip impacts the R-Value of wall cavities in a positive way. The product is commonly installed by the insulation contractor prior to applying the vapor retarder.

August 2001
In 1993, The Collins Companies became the first privately-owned forest products company in North America to be FSC-certified. Since then, every Collins product line from particleboard to softwood and hardwood lumber, has gone through the process to become FSC-certified. TruWood, from Collin Products, has become the first and only Forest Stewardship Council certified engineered siding in the world. TruWood siding replicates the random knots and meandering grain of Western Red Cedar. It was designed and crafted by a German artisan in Rochester, New York, who took a piece of Western Red Cedar and hand-chiseled and sculptured a precise mirror-image metal plate capturing the naturalistic irregularity that nature created.

The company has received Green Cross certification from Scientific Certification Systems that its particleboard is manufactured entirely from postindustrial waste fibers. While most particleboard manufactured today contains a high percentage of wood waste from other manufacturing processes, Collins is committed to using no virgin fiber in its particleboard.

Energy Alternatives

May 2010
In addition to offering the benefits of a traditional ridge vent, the Greenward system from Energy Alternatives harvests escaping hot attic air and uses it to preheat the incoming water of a hot-water tank. “This is not a solar system, although a majority of the heat comes from the sun,” explains Kevin B. Scott, president of Energy Alternatives. “It’s an ambient heat collector.”

 Introduced at last year’s GreenBuild show in Phoenix, the Greenward system utilizes flexible PEX tubing that contains a water/corn-based glycol solution that picks up the heat from escaping attic air. A differential temperature-control sensor, located by the ridge vent, is triggered when the temperature of the water in the storage tank is 20 degrees cooler than the temperature of the ridge vent. A circulator pump is then activated and pushes the hot solution down in a closed loop around the tank, where it heats up the incoming city or well water, before going back up to the roof area. “It’s a very low-tech solution for a high-tech problem,” says Scott. “A perfect example of utilizing existing energy that is normally wasted.” The system contributes to the Optimized Energy Performance credit in programs such as LEED for Homes and LEED for New Construction.

According to the manufacturer, the Greenward Ridge Vent can reduce energy consumption by just over 12 million Btus a year and reduce CO2 emissions by just over 1,400 pounds annually. Scott says that many variables, including climate, shingle color, and attic size, affect how the system performs. The company is still collecting data from test homes in Tucson, the Carolinas, and Atlanta. One test, held in New York State on a day with temperatures of 85 degrees Fahrenheit, showed the ridge vent temperature at 120 degrees and the solution at 100 degrees, which helped the system raise 80 gallons of water from 65 to 90 degrees.

The system was recently installed in a LEED-certified home built by Habitat for Humanity Saint Louis, Missouri’s largest green builder. “The product installed like any other ridge vent,” says Kyle Hunsberger, director of construction for the chapter. ”After that, the rough-in is just a matter of connecting the PEX lines to the location of where your storage tank will be.” He cites an easy install, discreet profile, and the elimination of unsightly solar panels as the main benefits of the system. Hunsberger is monitoring the utility bills for the home and hopes to use the system on future projects.

Scott claims a main advantage of the system is the price point — the complete system comes in under $6000, fully installed. While he sees interest nationwide, “the hotter the attic, the more hot water we will generate.” For those in colder climates, the solution in the tubing is formulated in order to prevent freezing. The system works with both traditional on-demand water heaters as well as tankless hot-water heaters, adds Scott, and will help prolong the life of the heater.

In February, Greenward won a Green Dot Award, which rewards excellence in environmental responsibility. This year, the system will be on display at the Western States Roofing Expo in Las Vegas in June and the GreenBuild show in Chicago in November. Scott says that this is just the beginning of his company’s role in the green marketplace. “This is our flagship product, and we have more products in the pipeline.”

Highland Craftsmen
www.barksiding.com
November 2005
Once the staple cladding for summer retreats in the Appalachian Mountains, Chestnut Bark became unavailable after the chestnut blight of the 1940’s. Today, Highland Craftsmen, a North Carolina-based manufacturer, is part of a “Bark House” revival, crafting shingles from more durable poplar bark.

Highland Craftsmen’s bark siding is kiln dried, which prevents shrinking and cracking once the bark shingles are applied to a structure. The bark contains no chemical additives, yet resists infestations and can meet stringent municipal building code standards for flammability.

Using careful harvesting methods, the team loosens whole cylinders of bark from trees fallen for other uses. The cylinders of bark are flattened and cut by hand into standard shingle length. After damaged or cracked sections are removed, the shingles are carefully stacked, and then placed under pressure to prevent curling. The stacks are then kiln-dried to the proper moisture content, sterilized, and then stored in a climate-controlled warehouse until ready to use.

The company offers a full range of complementary products to enhance a bark-shingle home, including handrails, posts, mantel pieces, custom furniture, and bark panels and sheets for interior applications.

HolzBuild

February 2007
A new pre-fabricated solid wood cladding option is now available from Austrian manufacturer Binder Holzbausysteme exclusively through their U.S.

representative, HolzBuild. The panels will be introduced at Construction Expo in New York City this May and at GreenBuild in Los Angeles in October.

Although the first U.S. project is still in the planning stages, the BBS panels have been in use in Europe for about five years. The multilayered, solid wood wall panels are made of Austrian Red Spruce or Larch, and come in 3-, 5-, 7-, and 9-layered versions. The standard panel width is 4.1', although multiple thicknesses and profiles are available. By laminating longitudinal and cross layers for the wall panels, the wood achieves greater strength and stability. Roof and floor panels are also available and feature two outer layers running in the same longitudinal direction on each side to improve stiffness and minimize deflection.

³One unique feature of these panels is that they are structural and have the potential to create a monolithic wall and therefore, a structural facade² says Antonio Guariento,owner of Holzbuild.

According to HolzBuild, a wall can be composed of vertically as well as horizontally placed panels. In fact often a panel (or part of a panel) is installed horizontally as a header above wall openings. The top side of the receiving panel can also be profiled to accommodate the joint between the panels.

The inner layers of the BBS panels are normally manufactured in Spruce and the outer layer in Larch, which is better suited to be exposed to the elements. The panels are made up of 99.4 percent solid wood and .6 percent formaldehyde-free glue, which also works as a liquid barrier.

Johns Manville
www.jm.com
June 2005 updated
Batt and blanket insulation products, including the company's ComfortTherm line, are certified by Scientific Certification Systems (SCS), a national leader in third-party verification of environmental related to product design. The SCS labeling on Johns Manville products includes a statement verifying that the glass fiber contains a minimum of 25 percent recycled glass, of which an 18 percent minimum is post-consumer remelted bottles, and 7 percent is pre-consumer glass.

Johns Manville will now manufacture a new line of entirely formaldehyde-free fiberglass building insulation for residential and commercial use. The insulation features a new binder composed of an acrylic resin rather than a phenol-formaldehyde binder. The change addresses concerns about indoor air quality in relation to building materials containing formaldehyde. Included in the line is EasyFit perforated fiberglass insulation. Vertical perforations in the fiberglass batts allow each section to be separated by simply tearing it apart instead of cutting, saving time and waste.

Spider, Johns Manville’s new spray-in formaldehyde-free, fast-dry insulation system, contains specially-designed glass fibers made primarily from sand. During the installation process, the fibers are mixed with a non-hazardous adhesive that eliminates the need for netting and dramatically speeds up drying schedules—on average more than six times faster than cellulose. When professionally installed, Spider reduces defects such as gaps, inadequate cavity-fill and settling, resulting in maximum thermal performance and reduced air movement. Spider reaches R-values of 15 in 2' x 4' wall cavities and 23 in 2' x 6' wall cavities.

Millennium Tiles
www.millenniumtiles.com
November 2005
Illinois-based Millennium Tiles claims to be the only manufacturer of stainless steel roofing and wall tiles worldwide. Initially targeted for the residential market, the tiles can be used in commercial and institutional projects as curtain walls or as a “green” roof to collect potable water or cut down on air conditioning needs. Competitively priced with high grade cedar, slate, clay or other metal roofing products, the Dade County-approved tiles are made of approximately 75 percent recycled material and are 100 percent recyclable. A built-in “shadow cup” adds the dimension of a more traditional shingle while significantly reducing noise.

In addition to the traditional silver color of stainless steel, Millennium Tiles can be colored with a prismatic process that raises the chromium oxide layer of the stainless. This process prismatically separates visible light into different wavelengths, resulting in different colors within the clear oxide surface. Since the oxide layer is clear, it is never subjected to UV deterioration and the color will stay the same for the life of the stainless. The only color change occurs in response to the light available during the day.

Currently, the tiles are produced in 9'' x 15'' or 7.75'' x 9'' sizes. In the next few months, Millennium will make the product in sheets as large as 48'' x 120'', which will allow for larger sizes to be fabricated. A complete accessory line of accent shingles and trim is available.

MonierLifetile, a Boral Roofing Company
boralna.com
February 2011
The photocatalytic properties of titanium dioxide allow the manufacturers of building products such as paints, cements, windows, and ceramic tiles to offer customers a “self-cleaning” benefit that is claimed to substantially reduce concentrations of airborne pollutants such as VOCs and nitrogen oxides. The latest entry into this category is a new concrete roof tile from Boral Roofing Company’s MonierLifetile division, known simply as Smog-Eating Tile.

 “This is ‘normal’ concrete roof tile,” explains Bob Pacelli, Boral Roofing’s marketing communications manager. “Its only difference is that it has a surface made from purely inorganic minerals that reduces the formation of smog and does not promote organic growth.” Although the technology was first developed in Japan, the roof tile is claimed to be the first of its kind in the United States. The tile contains a specially prepared catalyst embedded in the upper part of the tile body; when exposed to sunlight, the catalyst speeds up the oxidation process, resulting in reduced pollution.

“The titanium dioxide is applied as a coating on the surface of the tile’s micro-mortar, which makes it less porous than a conventional color-through tile,” says Pacelli. This gives the tile the added benefit of being mold- and algae-resistant. The technology, marketed as BoralPure, is available on the manufacturer’s high- and medium-profile and flat tiles in 11 colors.

Currently, the product is manufactured in Boral Roofing’s California and Nevada manufacturing plants, but there are plans to expand production into the manufacturer’s eastern plants throughout 2011, enabling the tiles to be shipped nationwide.

Smog-Eating Tile is featured on five “green” prototype homes by builder KB Home for its Alamosa community in West Lancaster, California, the first of which debuted at an event last July. KB Home collaborated with the City of Lancaster and the Chinese green-tech company BYD, which provided the homes’ solar, battery, and LED systems.  

“We are inspired by innovation and constantly seek out new technologies that reduce our homeowners’ overall impact on the natural environment and improve their quality of life,” says Craig LeMessurier, KB Home’s director of corporate communications. “The benefits of Boral’s smog-neutralizing tiles are quite dramatic, and we view this product as a revolutionary way to fight air pollution.”

While some design professionals may need more time to warm up to the new technology, the company has convincing numbers that demonstrate the roof tile’s potential for reducing pollution.

“Over a period of a year, 2,000 square feet of the tile can destroy approximately the same amount of nitrogen oxide as the average car produces driving 10,800 miles,” says Pacelli, “making this product one real way builders and owners can reduce the smog footprint and the diseases directly attributed to it.”

November 2004
After testing revealed straight strip products inhibit air flow in and moisture flow out of weep holes, Mortar Net has discontinued the company’s Mortar Mitt straight strip product. The dovetail design of Mortar Net’s standard Mortar Net product was found to be more effective for cavity wall drainage than straight strip. The testing also inspired Mortar Net to redesign their Weep Vent product to improve air flow. Weep Vents block insects and debris while allowing moisture to escape.

Rheinzink America, a leading manufacturer of titanium zincroofing, wall cladding, and rainwater systems for the construction industry, produces the Design Drainage systems made of Rheinzink. The alternative to conventional copper or lead-coated copper home accessories, zinc is a naturally-occurring material that is durable, lasting 80-100 years, and develops a patina that regenerates itself naturally, protecting the metal and reducing the need for costly chemical maintenance.

In a multi-phased expansion of the Navy Federal Credit Union’s Pensacola, Florida campus, three buildings and a parking deck/energy plant have achieved LEED gold status. Approximately 134,000 square feet of Rheinzink flat lock tile finished in graphite gray were used on two buildings and the parking deck (a fourth building is to come). The panels, chosen for their recycled content, durability, and self-healing nature, interact with and complement a masonry facade.

September 2005
Lotusan is an exterior coating recently introduced into the North American market by Sto that features a pronounced self-cleaning effect. Modeled on the microstructure of the lotus leaf (bottom, right), the coating features Bionics technology that imparts super-hydrophobic properties to the coating. The “Lotus Effect” is actually a natural phenomenon discovered on the Asian lotus plant—after each rainfall the plant leaves are immaculately clean and dry, as all the dirt has run off with the raindrops. The coating’s self cleaning effect (far left) makes it highly resistant to soiling, mold, mildew, and algae. Lotusan was first introduced in Europe in 1999, and has been applied to more than 300 million square feet of façade surfaces.

updated October 2006
GreenGrid, a division of Weston Solutions, introduces a new DIY Green Roofing System ideal for homes or smaller commercial buildings. The GreenGrid DIY Kit includes 2' x 2' x 4'' deep modules, GreenGrid¹s specially formulated lightweight soil media, and low-maintenance, drought-resistant sedum plants. After the soil media and plants are placed in the modules, the units can be placed directly on top of the existing roof. Although the system is light, the roof¹s structural integrity may need to be tested to verify it can support the extra weight.

The growth media engineered for Green roof systems must provide the nutrients necessary for the vegetation to survive and thrive in all types of climates and conditions. To accomplish this, Weston Solutions, manufacturer of the GreenGrid modular Green roofing systems, has developed a proprietary mixture of organic and inorganic growth media.

Formulated after years of research and field-testing, the growth media used in GreenGrid modular systems has the proper pH balance, air space, nutrients, and drainage to help maximize root development and improve plant growth, quality, and survival.
