March 20, 2024

The KEE-Stone HP is the newest addition to the family of KEE-Stone thermoplastic roofing membranes. This membrane incorporates one of the industry’s highest-quality ketone ethylene esters for superior flexibility, strength, and chemical and UV resistance. KEE-Stone HP is a fleece-backed thermoplastic membrane designed as the cap sheet in a multi-ply hybrid system incorporating Garland-approved modified bitumen base sheets. KEE-Stone HP meets and exceeds the ASTM D6754 certification, the standard specification for KEE-based sheet roofing. 

“The HP in KEE-Stone HP signifies high performance, a testament to the robust formulation, which delivers unparalleled weather, fire, and chemical resistance,” said Julie Ann Geyer, director of R&D for Garland.
