Get more Quality, Flexibility and Labor Savings using ROOF TRUSSES Wood Roof and Floor Trusses are Environmentally Compatible BUILDING GREEN: Using less gives more. Builders want solutions that help them stay on schedule and maintain quality construction and profits. When compared to traditional beam construction, manufactured wood roof truss systems are better, stronger, and can be installed faster. A manufactured truss is an engineered structural component assembled from wood members, metal connector plates and other mechanical fasteners. The truss members form a semi-rigid structural framework and are assembled such that the members form triangles. Trusses are designed to engineering standards with a substantial factor of safety applying to every truss in the roof. Most builders are familiar with roof truss systems, but may not realize the advantages of a manufactured system. Traditional stick built roofs which are based on historical conservative carpentry practices, use greater quantities of lumber to achieve acceptable factors of safety. The reserve strength of these traditional roofs is also variable and depends on the skill of the individual carpenter. home owners practice environmental responsibility and sustainability by conserving today's resources for tomorrow's children. Every effort is made to offer products that balance design and performance with environmental responsibility. There's no getting around it, the wood you purchase comes from one of the Earth's most renewable resources—trees. Wood is the most energy efficient of major building products. The benefits of manufactured wood truss systems are many. Trusses can span great distances, creating larger open spaces below unobstructed by columns and partitions. Roof truss systems are manufactured in controlled environments, so there's less chance of warping, shrinking, and twisting of lumber. Trusses also save timber resources by reducing the amount of wood waste generated during construction. The owner can enjoy piece of mind knowing that the trusses have been professionally engineered and quality manufactured for that specific job. Components minimize the amount of material used and jobsite waste created. This is a no brainer, but it's a good point to reinforce with builders and general contractors. And there's data to prove it! The 1996 WTCA Framing the American Dream® project reported a more than 25 percent material savings (and labor savings of more than 60 percent!) when components were used to frame a 2600-sq.ft. home. visit www.sbcindustry.com/pubs/fad-d to view a pdf. "Building Green" isn't new to the structural building components industry. In fact, we've been green since 1952! At ITW Building Components Group, we are committed to helping our builders, remodelers and Components are designed to utilize materials most efficiently. Don't forget that material efficiency is inherent to the process of component design. Design software from ITW Building Components Group allows the designer or technician to value engineer and optimize virtually any component design. This means material is not used when it isn't needed. Many green building rating systems recognize this benefit of components and award points based on their use. The National Resource Defense Council realized this fact in 1998 when they placed trusses high on their list of great products due to optimum value engineering.

The Benefits of Wood Trusses: A wood trussed-home costs less. The total in-place cost of trussed roof and floor systems is lower. Trusses are delivered to the site ready to be installed. Labor is saved because trusses can be installed three to four times faster than it would take a carpenter to build the roof on-site. The open spaces in the trusses allows duct work, plumbing and wiring to be installed quickly and easily. Construction costs also are reduced because the building is "closed-in" faster, there is less pilferage of materials, and it takes less time to clean up the site. You get peace of mind – knowing that the trusses were professionally computer-designed, engineered and factory-built to assure the highest quality and reliability. It's easy to remodel or make an addition because most interior walls can be moved if your needs change. Trusses allow virtually unlimited architectural versatility. That means designs can include vaulted or studio ceilings inside the home and high pitched or hipped roofs on the exterior, offering greater aesthetic and functional advantages. Proven performance – hundreds of millions of wood trusses have been installed throughout the country. In fact, wood trusses are used in more than 75% of all homes built in the U. S. and Canada today. Why Build Green? In the United States, buildings account for: 39 percent of total energy use, 12 percent of the total water consumption, 68 percent of total electricity consumption and 38 percent of the carbon dioxide emissions. The built environment has a vast impact on the natural environment, human health, and the economy. By adopting green building strategies, we can maximize both economic and environmental performance. Green construction methods can be integrated into buildings at any stage, from design and construction, to renovation and deconstruction. However, the most significant benefits can be obtained if the design and construction team takes an integrated approach from the earliest stages of a building project. Potential benefits of green building can include: Environmental benefits: Enhance and protect biodiversity and ecosystems, Improve air and water quality, Reduce waste streams and Conserve, restore natural resources. Economic benefits: Reduce operating costs, Expand markets for green product and services, Improve occupant productivity, Optimize life-cycle economic performance. Social benefits: Enhance occupant comfort and health, Heighten aesthetic qualities, Minimize strain on local infrastructure, Improve overall quality of life. www.epa.gov/greenbuilding/pubs/whybuild.htm Pre-engineered wood trusses are scientifically designed for strength. A pre-engineered framing system eliminates guesswork on the construction site. 2 www.itwbcg.com 1 1
