To be approved for use in building construction, products need to be tested and evaluated to the requirements of building codes by appropriate third-party entities. In the rapidly evolving market for building materials, a manufacturer’s ability to demonstrate its products are code-compliant is critical to gaining approval for use in the thousands of jurisdictions across the nation. This code evaluation process can be time-consuming, and can impact timelines for introduction of products into the market.
Many designers and specifiers understand controlling air, vapor, and thermal transfer helps mitigate moisture problems within the building envelope. Moisture accumulation is a performance adversary that can lead to structural deterioration, finish damage, organic growth, and reduced building longevity.
To help translate what the latest changes to building codes mean for opportunities in wood construction, the American Wood Council (AWC) has introduced four new standards that are adopted by reference in the 2015 International Building Code (IBC) and the 2015 International Residential Code (IRC).
The 2015 edition of the ANSI/AWC Wood Frame Construction Manual (WFCM) for One- and Two-Family Dwellings provides guidance for wood-frame construction in residential as well as commercial structures that fit within its scoping.
Historically, glazing has been used to provide light and ventilation in building walls as its primary function. In contemporary buildings, specialized glazing can provide numerous other functions, including fire-resistance.
