Electrical Box Protection
Protecting Electrical Boxes in Fire-Rated Walls
Recessed electrical socket boxes and switches can create openings within a fire-rated partition. Intumescent putty pads are designed to help protect these openings as part of an appropriate tested wall system.
The flexible pad is installed around or behind the electrical box in accordance with the manufacturer's instructions.
When exposed to high temperatures, the intumescent material reacts and expands, helping maintain the integrity of the surrounding compartment wall.
Common applications
- Electrical socket boxes
- Switch boxes
- Recessed electrical fittings
- Plasterboard partitions
- Compartment walls
How They Work
Fire & Acoustic Protection Around Electrical Boxes
Putty pads provide a practical method of protecting recessed electrical fittings within suitable fire-rated wall systems.
Fits Around the Box
Flexible putty material can be formed around the electrical box or fitting in accordance with the relevant installation instructions.
Reacts to Heat
The intumescent material reacts at elevated temperatures and helps seal openings around the fitting within the tested system.
Acoustic Performance
Some tested putty pad systems can also help reduce sound transmission through electrical box penetrations. Check the product documentation where acoustic performance is required.
Specification
Choosing the Right Intumescent Putty Pad
Check the electrical box and wall construction against the relevant tested system before installation.
Box Type

Wall Construction
Confirm the wall type, board build-up and cavity arrangement permitted by the tested system.

Technical Guidance
The electrical box forms part of the wall detail
A putty pad should not be selected only by the dimensions of the electrical box. Wall construction, box material and size, box arrangement, product position and required fire resistance can all form part of the tested configuration.
Always install putty pads in accordance with the relevant manufacturer instructions and supporting fire test or classification documentation.
What information should I provide?
If you need help identifying a suitable product, it helps to provide:
- Electrical box type
- Box dimensions
- Wall construction
- Board and cavity build-up
- Required fire resistance
- Number and position of boxes
Frequently Asked Questions
Intumescent Putty Pad FAQs
Intumescent putty pads are passive fire protection products used around electrical socket boxes, switches and other recessed electrical fittings within fire-rated walls.
Putty pads contain intumescent material that reacts when exposed to high temperatures. Within an appropriate tested system, it expands to help seal gaps around the electrical fitting.
Putty pads are commonly fitted around or behind electrical back boxes and recessed electrical fittings installed within fire-rated plasterboard partitions and compartment walls.
Some tested putty pad systems can also provide acoustic performance. Check the relevant product documentation where acoustic performance is required.
Selection depends on factors including the electrical box type and dimensions, wall construction, required fire resistance and the relevant manufacturer's tested installation detail.
