Why Calcium Silicates From Leader Factory?

Calcium silicate for fire protection

Calcium silicate materials from Leader ® can perfectly combine  thermal insulation ,  fire protection  and  acoustic insulation . They are used to protect timber, concrete or steel structures, or as self-supporting components such as partition walls, ceilings, and ductworks. Finished with an aesthetic covering, they are an all-in-one architectural element, enabling fast building and saving space. Leader’s calcium silicate materials are entirely safe, easy to ship, store, handle and install, which makes them the material of choice for planners, architects and applicators. 

Calcium silicate insulation - thermal and mechanical performance 

Leader’s calcium silicate materials for high temperature insulation cover the complete range of low, medium and high density and compound insulation boards. They offer a very low thermal conductivity and excellent structural support, and are resistant to moisture and chemicals. Due to their minimal thermal shrinkage they have an extended service life without loss of performance.

The excellent structural integrity of our calcium silicates makes them easily machinable and even enables the machining of complex structures. Moreover, they are easy and safe to handle, install and maintain, and can be used for new constructions as well as retrofits.
