Curtain Wall Fire Stop Board

Curtain Wall Fire Stop Board Curtain Wall Fire Stop Board 1 Curtain Wall Fire Stop Board 2 Curtain Wall Fire Stop Board 3

Curtain Wall Fire Stop Board is specially designed for all types of curtain walls. The product has higher temperature resistance, higher melting point, longer fire resistance time and smaller high-temperature linear shrinkage.

CFC series can be use not only as the fire and smoke stop barrier between curtain wall and floor or curtain wall and partition, but also as the barrier between other construction gaps around wall penetration pipes or floor penetration pipes. In order to enhance the smoke barrier capability of CFC series, fire proof aluminum foils are generally attached to both sides of the rock wool.

WFS series is mainly used as the fire barrier and insulation for spandrel in curtain wall system. Its outstanding thermal insulation property can effectively reduce the heat transmission in the section. WFS series can be attached with facing material such as aluminum foil.
