Grenaboard is a very light and strong non-combustible board produced from vermiculite and inorganic binder. This board is surfaced on both sides with paper and all four edges pressed for easy connection.
Grenaboard is certified in fire membrane function for various types of ceiling structures, either hanging the ceiling structure, or derectly on a wood beam ceiling.
Only one worker is required to install. Installation is the same for all types of ceiling structures and fire resistance.
Higher base price of the board is compensated by lower price for mounting profiles and elements and significantly less laborious assembly.
Reaction to fire according to ČSN EN 13501-1: A1 – non-combustible
