1 1/2 in x 12 in x 12 in Calcium Silicate High Temperature Insulation MPN:684702
1 1/2 in x 12 in x 12 in Calcium Silicate High Temperature Insulation
This high-temperature insulation board from Johns Manville is designed for use in applications where extreme heat is present, such as industrial furnaces, kilns, and refractory linings. Its calcium silicate material provides a stable, non-combustible barrier that resists heat damage and maintains its insulating properties even at temperatures up to 1,700°F. The board's low water vapor absorption and minimal thermal conductivity make it ideal for use in environments with high moisture levels. Its compact size and lightweight design make it easy to install, and its flexibility allows for easy cutting and shaping to fit specific applications.
