The Problem with Socket Boxes & Putty Pads

Fire & Smoke pathway

A recessed switch or socket presents an easy path for fire and smoke to spread from room to room.

Building Regulations Approved Document B states that any penetrated fire rated wall should be reinstated to its original fire rating. The Electrical Safety Council Best Practice Guide also recommends fire stopping of socket box openings.

Increased noise transmission

Penetrations in a wall reduce acoustic performance, which should be reinstated as per Building Regulations Approved Document E.

Reduced energy efficiency

Wall penetrations are a considerable source of  heat loss. Recessed switches and sockets offer an easy path for air
leakage and due to the high number of units in each building represent a high total air leakage. Many building are now specifically tested to meet air leakage criteria before being "signed off" - this is covered in Building Regulations Approved Document L.

The old solution was to fit Putty Pads - a time consuming and messy business - but now there is an alternative.
