Rock Mineral Wool - DRS FIRE BOARD 2D*



Boards for fire-screen doors with higher density on the upper side of the door core

Knauf Insulation DRS FIRE BOARD 2D* (DRS FB 2D*) is a patented rock mineral wool board with innovative density distribution that provides a higher density on the fire-critical upper side of the door core. Compared to the nominal density in the middle, the density is higher on the upper side of the board (up to + 30 kg/m3) and lower on the bottom side of the board (down to - 30 kg/m3).

*Knauf Insulation DRS Fire Board 2D is not for sale or use in Germany, other than to licensees of German patent DE 103054221 of Hörmann KG Freisen
