Rockwool FirePro Intumescent Pillows
Building services often need to pass through fire-resisting walls and compartmentation elements. Rockwool FirePro intumescent pillows provide a specialist firestopping option for suitable service openings, particularly where future access or changes to services may be required.
For contractors and facilaties teams, understanding the purpose of fire pillows can help when planning installations and future maintenance.
What are intumescent fire pillows?
Fire pillows are bags containing intumescent material. They are installed tightly within suitable openings around building services to form part of a specified firestopping system.
When exposed to fire, the intumescent material expands and forms an insulating char layer, helping seal the opening within the tested installation.
Where are fire pillows used?
Depending on the product and approved configuration, Rockwool Fire Pro pillows can be used for suitable service penetrations involving metal pipework, plastic conduits and cable trays or ladders.
Their design can make them useful in locations where services may need to be changed or replaced, provided the system is installed and maintained in accordance with its instructions.
What should contractors consider?
Before selecting fire pillows, check the wall construction, opening dimensions, service types and required fire performance.
The correct pillow arrangement and installation details must follow the manufacturer's guidance. Do not assume every pillow system is suitable for every service or opening.
