PROMASIL® lightweight calcium silicate insulation boards have excellent thermal and mechanical properties. These rigid boards are ideally suited for high temperature applications, especially in all types of furnaces. In combination with dense and lightweight refractory bricks or concrete, the boards constitute a thin and efficient back-up insulation lining.

The PROMASIL® range consists of various medium and large-size insulation boards with different densities and temperature grades, designed for specific applications.

Apart from rigid insulation boards, PROMASIL® materials are also available as pipe sections, segments and cut sections, that are clean and easy to handle and install.
