Asbestos Free

HI-THERM®        CALCIUM SILICATE

(Made in China)

 

HI THERM® Calcium Silicate is molded pipe/block with 3 feet and 2 feet length.

The diatomaceous earth and lime substance reinforced with inorganic glass fiber gave natural off-white color, totally asbestos free. Remarkable strong and rigid and its light weight, low thermal conductivity, water resistance ability to withstand repeated wetting and heavy traffic abuse.

HI THERM® Calcium Silicate insulation materials have been widely accepted by international engineering design & build engineers.

HI THERM® Annual production 2 million cube metre. Materials have been supplied to Canada, South America, Far East and all over middle east countries.
