Build better with T-STRAND Pro. Our SIP Facers offer increased moisture resistance, with our edge seal which protects against swelling. To ensure our product arrives at your door in the same condition it left our mill, we ship our SIP Facers in a woven-poly bag for extra protection against the elements.
