Proper Panel Spacing
It is important to properly space OSB and Plywood panels to allow for natural expansion as they adjust to the moisture in the environment. APA the Engineered Wood Association recommends 1/8-inch space between panels for a smooth and secure surface without buckling. For more information, view the following resources from APA:
SHEATHING
Residential Sheathing
Build better with T-STRAND. Your choice of material can make life on the job-site easier. Our T-STRAND OSB Sheathing features an ink-jetted nailing guide on the panel face, which makes for convenient, easy installation, and our proprietary edge seal creates a moisture resistant panel which resists swelling.
To keep our air clean, our OSB contains no added urea-formaldehyde resin (NAUF) for improved indoor air quality.
SIP FACERS
SIP Facers
Panel matching made easy. Laminating structural insulated panels (SIPs) can feel like putting together a puzzle, with OSB boards that never quite seem to fit. To help you get the quality you want and avoid the stress of finding just the right piece for your project, we offer our dimensionally stable and consistently straight OSB SIP Facers.
