Description

Consisting of an inner and outer plate for one side of the door or wall and a plain plate for the other side. The inner and outer plate houses the intumescent material which, in a fire, would seal up slots and louvres, giving one hour fire protection. Two types of plates are supplied: for louvred add /L after the reference. A door requiring protection on the risk side only (i.e. room door) require one set of MG/S or MGL/S. A door requiring one hour protection to both sides (ie. corridor or top of stairs), require one set of MG/D or MGL/D. Made in 15 standard sizes, the grilles are finished in brown, white and stainless steel. Other sizes and colours are made to order.

MG slotted type for more ventilation/MGL louvred non-viewing type. Each slot gives 6cm2 and louvre 3.2 cm2 free ventilation area.

APPLICATION INSTRUCTIONS

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). See price list for full range of available sizes.
