Grilles must be fitted in the correct orientation, ie height = vertical and width = horizontal measurements.
Envirograf Intumescent MG & MGL Grilles allow airflow through doors and walls via a slotted design or a louvre style for privacy. Both styles have intumescent material that expands during fire, sealing up ventilation to prevent the spread of flames and smoke for up to an hour, containing a fire to help aid evacuation and prevent more damage to a building.
Supplied in sets of 2, in 2 configurations; double plates are for when fire could attack from either side of a door or wall, and single-sided is for when only one side is at risk of fire.
The sets are defined in two ways: the /D version is for use in situations in which the risk is double-sided (that is, the opening could be attacked by fire from either side); and the /S version is for use in situations in which it has been clearly identified that only a single side of the opening is at risk.
When fitting the /S version, the intumesced plate is placed on the risk side and the plain plate is placed on the opposite side of the opening.
Order the grilles to suit the opening to be protected – the external measurement of the grille needs to be at least 50mm larger than the opening to allow for fixing.
Special sizes can be produced (prices quoted on request).
