Building Regulations impose limitations on all pipes passing through fire compartment walls and floors. Quelfire QWX Fire Collars allow plastic pipes to meet the requirements of the Building Regulations. Quelfire QWX Fire Collars have been tested according to BSEN 1366-3: 2009 where pipe diameters of up to 400mm have met insulation and integrity criteria for this standard for up
to four hours.


Quelfire SS Slabs are manufactured by spraying specially produced, high density insulation with an additional fire protection ablative coating.


Quelfire SS System is expected to last the lifetime of the service installation.

Application / Installation

SS Slabs are simply cut and a bead of GM Intumescent Acoustic Sealant applied around the external edges.
They are then friction fitted between the services and the wall or floor edges to completely seal the void. Where butt joints are required between cut sections of adjacent batts, Quelfire GM Intumescent Acoustic Sealant should be applied to both edges in order to form a fire tight bond between individual pieces of insulation.

All joints, including those around the perimeter of the slab and around all penetrating services are then pointed with Quelfire GM Intumescent Acoustic Sealant to complete the seal.
