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 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 GM Intumescent Acoustic Sealant.
