SillGuard
Marvin. SillGuard is a durable sill pan system that provides builders and installers with an effective and cost-efficient means of minimizing the potential for moisture penetration and subsequent wall damage, the firm says. It is a rigid three-piece sill pan made from polypropylene. The recycled, non-corrosive, and thermally non-conductive material allows SillGuard to resist cracking or shattering, even in cold environments, the manufacturer says. 888-537-8266. www.marvin.com.
