Product Description
ASBESTOS FREE CALCIUM SILICATE INSULATION BOARD
Comparing with dense and lightweight refractory bricks or concrete, calcium silicate are the ideal rear lining construction material for all kind industrial furnace and kilns. As generally known, the low thermal shock resistance of calcium silicates excludes its use on the front side. Calcium silicate insulation materials can be produced as boards, pipe sections, segments and cut sections.
