Credits: 1.00 HSW
Wood-framed construction is the predominant method of building homes in the U.S. and has gained steady acceptance in light commercial and industrial buildings. The inherent strength of wood-framing, its cost effectiveness, and energy efficiency have been borne out in hundreds of years of use. Yet todayâ€™s high energy prices, changes in building codes, and growing awareness of building performance and environmental sustainability have led to the development of products and practices that strengthen wood framing as a preferred construction method. This article will focus on wood-framed roofs, their basic anatomy, and the best practices that lead to high performance.
Anatomy of a Wood-Framed Roof
Dimensional lumber or engineered wood is typically installed equal distances apart to create the support structure of a wood-framed roof assembly. The framing is sheathed with plywood or oriented-strand board (OSB), then layered with various underlayment materials before the finished roofing materials are attached. A key consideration is the type of roof construction, stick built or truss. Each has its advantages and disadvantages.
High-performance wood-framed roofs contribute to building durability, comfort, and energy in any climate.
