Building Regulations impose limitations on all pipes passing through fire compartment walls and floors. Quelfire QRS Intumescent Fire Sleeves allow plastic ducts to meet the requirements of the Building Regulations. Quelfire QRS Intumescent Fire Sleeves have been tested according to BSEN 1366-3: 2009 where various plastic duct sizes have met insulation and integrity criteria for this standard for up to 2 hours.



The Quelfire QRS Intumescent Fire Sleeves consist of a flexible galvanised steel shell containing graphite based intumescent material. They are manufactured to suit flat ducts of 110x54mm, 205x60mm, and 220x90mm. And round ducts with 75mm, 100mm
and 125mm overall diameter.


Tested to Type X durability which means the QRS Fire Sleeves can be installed in conditions exposed to weathering. Quelfire QRS CE Marked Fire Sleeves are expected to last the lifetime of the building.

Application / Installation

The Quelfire QRS Intumescent Fire Sleeve should be placed around the ventilation duct, positioned centrally within the partition and should be flush or protrude from each face of the wall. The plasterboard should be cut to a tight fit around the Quelfire QRS Intumescent Fire Sleeve, and any gaps should be sealed with the Quelfire GM Intumescent Acoustic Sealant.
