Fire protective construction board

PROMATECT®-XS is a non-combustible fire protective board. Thanks to its properties it guarantees protection of structures from R 30 up to R 240. The PROMATECT®-XS board is also characterized by very good mechanical properties such as impact resistance, stiffness as well as bending strength and compressive strength. PROMATECT®-XS has got a straight longitudinal or a rounded edge. It does not contain dangerous compounds – it is environmentally friendly and recyclable.
