Calcium Silicate Board

Calcium Silicate Board – High temperature insulation

NR-1000 calcium silicate board  is  white and hard high temperature thermal insulation material based on lightweight calcium silicate with high strength, low thermal conductivity, lightweight, pressure-resistant character, it can be used at most different areas of industry as backup insulation. In particular for the construction of industrial furnaces, dryers and apparatuses but also in the cement and petrochemicals industries, it is the classical cost efficient insulating material.

In addition to its outstanding thermophysical properties,  NR-1000 calcium silicate board is resistant to the reducing protective gases, H2, CO, CH4, NH3, N2.

NR-1000  calcium silicate board are large-size, lightweight asbestos free insulating boards.

In combination with dense and lightweight refractory bricks or concrete, calcium silicate boards are the ideal rear lining construction material. it can be manufactured as boards, pipe sections, segments and special shapes according to drawings.
