Fire Rated Air Transfer Grille (Intumescent Fire Blocks)

Manufactured from high performance intumescent material that is formed into square or rectangular shapes and contained within a steel frame, for use in fire resisting door sets and compartment walls to provide up to 60 minutes fire resistance.
 
In normal use the grilles allow air to be circulated and moved throughout the building; however on exposure to heat from a fire the intumescent material swells to produce a fire resistant seal against the passage of fire, smoke and hot gases.
 
The grilles are easily installed in vertical apertures in doors or walls.
We also supply square or rectangular steel louvered faceplates in a silver finish to provide an aesthetically pleasing appearance.
 
The product has been independently tested by Bodycote/Warrintonfire to BS476 part 22:1987 for 30 and 60 minute fire resistance.
Test Reports 146520/146521 & 148053 apply – combined within Assessment Report No. 149511
