1/2 in x 24 in x 48 in Calcium Silicate High Temperature Insulation MPN:638324
1/2 in x 24 in x 48 in Calcium Silicate High Temperature Insulation
This high-temperature insulation from Johns Manville is designed for demanding applications where extreme heat is a concern. Made from dense calcium silicate, it maintains its integrity and performance at temperatures up to 1700°F. The unfaced board provides a clean and consistent surface for finishing, while its low water vapor absorption minimizes the risk of condensation and degradation. Suitable for use in industrial processes, kiln furniture, and other high-temperature settings, this insulation offers reliable thermal performance and durability. Its compact size and lightweight design make it easy to handle and install, reducing labor costs and improving project efficiency.
