Technical Information
Technical Information
Regulations
Building Regulations impose limitations on all pipes passing through fire compartment walls and floors. QRS Intumescent Fire Sleeves allow plastic ducts to meet the requirements of the Building Regulations. 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.
Composition
The 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, 204x60mm, and 220x90mm. And round ducts with 100mm and 125mm overall diameter.
Durability
Tested to Type X durability which means the QRS Fire Sleeves can be installed in conditions exposed to weathering. QRS CE/UKCA Marked Fire Sleeves are expected to last the lifetime of the building.
Applications/Installation
The 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 QRS Intumescent Fire Sleeve, and any gaps should be sealed with the Quelstop Intumescent Acrylic Sealant, part number QSS310.
For all sleeve types, please refer to manufacturers installation guidance prior to system design or installation.
