G8HD Door grille, fire resistant

These grilles are manufactured from grey synthetic louvres filled with intumescent material. At a temperature of 120° Celsius the louvres swell to many times the original thickness and fuse together to form a non-combustible barrier. Grilles are supplied with an anodised aluminium frame and matching back frame. Gaps between the grille and surround should be filled with fire resistant mortar or intumescent mastic. Free-air space approx. 86%.

Application

In effect the grilles act as a static fire barrier. The grilles are not suitable for front doors. This application is detailed in section G8HP
