QRS CE Marked 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 CE Marked Intumescent Fire Sleeves can be installed in conditions exposed to weathering. QRS Fire Sleeves are expected to last the lifetime of the building.

Standards & Approvals
Building Regulations impose limitations on all pipes and ducts passing through fire compartment walls and floors. QRS CE Marked Intumescent Fire Sleeves allow plastic ducts to meet the requirements of the Building Regulations. QRS 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.
||Duct size (mm)
||Space needed around duct to fit QRS (mm)

*QRS90, QRS130 and QRS110 are not currently CE Marked
The QRS CE Marked 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 QRS Fire Sleeve, and any gaps should be sealed with the QSS QuelStop CE Marked Intumescent Acoustic Acrylic Sealant.
The QRS Fire Sleeve can also be installed within the QB50 QuelStop Fire Batt.
