Properties of Grenamat A

The non-combustible GRENAMAT A board is made of only natural materials – exfoliated vermiculite and special inorganic binder. It is harmless to health, does not contain asbestos or any other substance listed in the List of Hazardous Substances of Very High Concern (SVHC) published by the European Chemicals Agency (ECHA).

The boards do not contain any reinforcement fibers because they are sufficiently strong due to compression of the material under high pressure. They are made of 100% ecological material and their residues can be disposed of as conventional building waste.

Grenamat A has been awarded the Marine Equipment Directive (MED) – B-0 and B-15 for the use of the shipboard industry all over the world in the category of partitions and ceilings. Grenamat A is supplied and installed on all types of ships – yachts, cruise ships, ferry boats, residential and work boats.
