Lightweight insulation for furnaces

PROMASIL® lightweight calcium silicate boards have excellent thermal and mechanical properties, making them ideally suited for high temperature applications, especially in all types of furnaces. PROMASIL® is available as boards, pipe sections, segments and cut sections, and is easy to machine and install.


Thin and lightweight insulation

PROMALIGHT® microporous insulation boards and custom-made machined parts have an excellent thermal performance, ideally suited for high temperature applications with limited available space. PROMALIGHT® is available in various coverings (PE and aluminium foil, and mica).


Reliable blast and impact protection

Our DURASTEEL® calcium silicate boards are covered in perforated galvanised steel, making them a solid base for a wide range of barrier systems for hydrocarbon and pool fire ratings, blast resistance, and protection against liquid glass and metals.
