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.

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
www.holzbuild.com
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.
