Monolux® and Monolux® MST are calcium silicate based building boards, reinforced with selected fibres and fillers to give the materials low thermal conductivity and high strength. These high temperature insulation boards do not contain any asbestos or inorganic fibres and can be easily machined to close tolerances. Both grades offer effective, stable insulation for demanding applications and have low shrinkage and good rigidity properties at elevated temperatures.

Monolux® (formerly Monolux® 800) is a superior grade, offering improved nominal density and thermal conductivity over Monolux® MST (formerly Monolux® 500). Monolux® is used in more demanding mechanical applications and is often used for platen presses and industrial dryers as thermal insulation. Our MST grade is commonly used as a thermal brake in many applications and can also be used as a single insulating skin in industrial ovens and dryers.


Platen press, ovens and dryers, load bearing pipe supports, heat shielding, structural thermal breaks, boiler baffles, flue gas baffles, fire resisting constructions, linings and machined components.
