APA Delivers Confidence

When you see fully sheathed wood walls with APA’s stamp, you can be confident the home is built with the materials required to meet the most stringent bracing methods. Since the early fifties, APA has collaborated with code bodies to improve wall performance. This collaboration has included a significant evolution in the use of prescriptive wall bracing techniques specifying plywood and OSB. In high wind and seismic events, APA’s expertise is on display with products that meet the industry’s highest performance standards and wall bracing applications aimed at reducing the risk of catastrophic home failure.
