PROSOCO, established in 1922, is a manufacturer of high performing fluid applied air & vapor barriers integral for roof to wall transitions that are essential for air barrier continuity. Controlling the leakage of air and water is fundamental to designing an energy efficient building. PROSOCO introduced R-Guard fluid applied products to solve problems & failures with existing techniques. R-Guard's effectiveness and easy application has driven industry acceptance of fluid applied technology. Performance tested and proven to withstand code-requires AND extreme weather conditions. R-Guard protected buildings are more durable, resilient and sustainable. Our understanding of building science, and our contribution to industry sustainability standards make R-Guard stand out among fluid applies systems.
