Description

The use of recessed switch and socket boxes in walls is widespread in private, public and commercial buildings. The walls are subject to fire regulations and most will have to be fire rated.

Once a hole is made in the wall for a recessed switch or socket box, the fire integrity of the construction is compromised: in addition the ability for the wall to provide an effective acoustic barrier is also impaired. For timber framed buildings preventing a fire from entering wall cavities and attacking the structure is critical to the overall fire integrity of the building.

To combat these fire risks ASTROflame, as part of its continuing development of passive fire and acoustic protection solutions, has developed a socket / switch fire and acoustic protection cover as an easy fit alternative to conventional putty pads.

These intumescent covers have been developed to provide maximum protection for wall penetrations created by the introduction of single and double recessed switch / socket boxes. Easy to fit they restore and maintain fire insulation and integrity in plasterboard walls for up to 120 minutes.

In a fire situation, the cover expands internally to fill all of the available space with a fire resistant highly insulating char. The fire is unable to penetrate the hole and the cover is able to give additional insulation protection to the wall void by reducing the chance of heat build up and the ignition of flammable structural members.

The penetration in the wall also provides a path for air (creating heat loss and drafts) and noise transmission - fitting an ASTRO FRA Socket Box Cover reduces these problems.

The one-piece socket box is designed for most common single & double electrical boxes. In a wall with two layers of plasterboard on each face, the ends of the fixing wires can be pushed between the plasterboard layers.
