Promat SUPALUX 12mm Fire Rated Board

The 12mm SUPALUX® Calcium Silicate Board is a premium fire protection and construction board designed for applications where maximum fire safety, moisture resistance and long-term durability are required. Manufactured by Promat, this high-performance calcium silicate board provides a reliable solution for residential, commercial and industrial projects where space-efficient, non-combustible construction materials are essential.

Unlike standard plasterboard products, SUPALUX is classified as A1 non-combustible in accordance with EN 13501-1, making it suitable for demanding passive fire protection applications. The board is manufactured using calcium silicate reinforced with selected fibres and fillers, while being produced without inorganic fibres and without added formaldehyde.

The 12mm SUPALUX board offers excellent dimensional stability and maintains its structural performance when exposed to moisture, humidity and changing environmental conditions. It will not rot, swell or physically degrade when used in damp areas, making it suitable for applications where conventional boards may not provide sufficient durability.
