Grenamat AS 20mm 600 x 800 mm 1150C

Grenamat AS size 600 x 800 mm T. = 20 mm
Grenamat AS is fire-resistant boards made from expanded vermiculite and special inorganic binder that provide a high degree of heat resistance to temperatures up to 1300°C and heat shocks. The boards do not represent any health hazards and are exclusive of any asbestos, glass or mineral fibres. They feature sufficient rigidity and mechanical stability, high temperature and high electrical resistance and low heat conductivity.
A non-combustible board made from the expanded vermiculite and inorganic binder. It contains no mineral or glass fibres or asbestos. It is both ecological and resistant to temperatures up to 1200°C. The boards feature good sound-absorbing and thermal insulating properties.

Reaction on fire as per EN 13501, DIN 4102 je A1.
Another advantage of the vermiculite boards is that they are easy to be worked by using normal wood-working tools. Various surface finishes can also be applied to the surface easily.
Grenamat A non-combustible board is used to protect the marine constructions against fire and to build the ship partitions, walls, ceilings, interior components and the furniture
