Where pipes, cables and ducts pass through a fire-rated wall or floor, the gap around them must be sealed so the fire cannot spread to the next room. That is what fire collars, wraps, boards and sealants are for – the system is chosen by the wall type and the services passing through.
Collars and wraps with intumescent infill for plastic pipes
Fire-stopping sealants – acrylic and intumescent mastics
Coated stone wool boards for larger penetrations
Tested to EN 1366-3 (penetrations) and EN 1366-4 (joints)
Class EI to EN 13501-2
How to choose
The solution depends on the wall or floor type, the pipe material and diameter or cable type – and must match the manufacturer's tested system. For a quotation we need a list of penetrations (type and diameter of services, quantity), wall or floor type and thickness and the required EI class; it is best to send a bill of quantities or photos of the penetrations.

Frequently asked questions
How does a fire collar work?
The collar has an intumescent infill that swells in a fire and squeezes the plastic pipe shut as it softens – so the opening in the wall stays closed.
Can a penetration be sealed with ordinary sealant or foam?
No – the seal must be tested for the specific wall type and services. Ordinary sealant or foam does not hold back fire, and such a penetration will not be accepted at building inspection.
Is a collar needed on both sides of the wall?
It depends on the tested system – in walls a collar is often needed on both sides, in floors only on the underside. Installation follows the manufacturer's instructions for the specific system.
