Fermacell Firepanel A1 Board
Description
A1 classification for interior finishes is increasingly in demand across Europe, particularly for public buildings utilizing dry construction methods. This is due to the harmonization of fire protection tests and fire safety classifications, which has resulted in stricter national requirements for building materials and structural elements.
Fermacell Firepanel A1 is specially designed for these applications. A new composition and the use of non-combustible fibers have made this possible.
