AIM Wall Cavity Barrier & Fire Barrier Slab
Foil Faced Mineral Wool Fire and Smoke Barrier for all cavity walls and curtain walls, horizontal and vertical use
Introduction
AIM Wall Cavity Barrier is made from foil faced high density rock wool and is suitable for use in all cavity walls, as well as for fire stopping between a curtain wall system and a concrete floor slab.
The barrier prevents the passage of flame and smoke for the period of fire rating, specified below.
Wall Cavity Barrier is offered cut to suit cavity width, or supplied as Fire Barrier Slab for cutting to size on site. The foil facing is imprinted with the AIM logo and arrows which ensures authenticity of the product and assists with the cutting procedure, when slab is used. The Barrier is supplied unfaced when 50mm wide or less.
The barrier is permanently held in place by compression and by clips when used in the horizontal, without the need for adhesive or intumescent mastic. Wall Cavity Barrier is available notched and in non standard lengths.
Curtain Wall Systems
AIM Wall Cavity Barrier is suitable for use in curtain wall cladding systems. However the performance of the fire barrier is dependent upon the integrity and stability of the cladding system in the region of the barrier, for the duration of fire rating required.
In addition to this consideration, should the curtain wall cladding bow or distort significantly in a fire, the gap that the fire barrier is filling may widen and integrity will be lost. If this is a possibility, the cladding system must be attached to the structural floor, close to the fire barrier, with steel brackets to ensure that the distance of separation cannot increase.
There are a great variety of Curtain Wall Cladding Systems available. The system manufacturer must confirm suitability of its use with fire barrier for the fire resistance period required.
