Built to Protect.
Engineered to last.
For 150 years, we’ve been building science nerds in the best possible way. We make drainable housewraps, rainscreen systems, self-adhered roof protection, and flashing products that keep moisture where it belongs: outside. Your reputation’s on the line with every build; ours is too.

Whole Home Protection is Here
Benjamin Obdyke’s Whole Home Protection approach delivers integrated solutions that work together to manage water, air, vapor, and ventilation throughout the building envelope. From self-adhered weather barriers and drainage products to roof and wall ventilation systems, each component is designed to enhance durability, improve energy efficiency, and provide long-term protection against moisture-related issues helping create healthier, more resilient homes from foundation to roof.
Featured Products
HydroGap SA
HydroGap SA is a self-adhered weather-resistant barrier that combines a high-performance acrylic adhesive with an integrated drainage gap to help manage bulk water and moisture. Its repositionable installation, nail sealability, and durable bond provide enhanced protection while simplifying the installation process.
VaporDry SA
VaporDry SA is a self-adhered vapor-permeable roof underlayment designed to help the roof dry while maintaining a continuous protective layer. The acrylic adhesive delivers long-term durability, repositionability during installation, and reliable nail sealability for improved building envelope performance.
AeroNet
AeroNet is a high-performance ventilation mat designed for both roof and wall applications, creating a continuous airspace that promotes drainage and airflow behind exterior claddings and roofing materials. Its enhanced compression resistance helps maintain that critical ventilation gap under load, supporting long-term moisture management, system durability, and overall building envelope performance.
