Calcium Silicate Valve Covers

Calcium silicate valve covers are made from calcium silicate insulation and are designed to protect pipes from damage by providing thermal insulation. Calcium silicate insulation is a high temperature, water resistant insulation that can be used in applications up to 1200°F. Known for its high compressive strength and durability, calcium silicate maintains its structural integrity even at extreme temperatures. View our selection of CalSil valve covers below!
