Intumescent Slim Fire Sleeve | QRS
Description
Description
The QRS Fire Sleeve is specifically developed to help prevent the spread of fire through plastic ventilation ducts as they pass through compartment lines.
Built with a tough pressed steel outer shell and a high-performance graphite-based intumescent core, the sleeve reacts instantly when exposed to fire. The intumescent material expands rapidly, closing the duct opening and maintaining the integrity of the fire barrier once the plastic duct has melted away.
Versatile in its application, the sleeve can be retrofitted to existing ducts, installed in clusters to protect multiple penetrations, and is fully compatible with the QuelStop Fire Batt system.
Standards & Approvals
Standards & Approvals
Quelfire QRS Intumescent Fire Sleeves are designed for use where plastic ventilation ducts pass through fire-rated walls, helping to maintain compartmentation and prevent the spread of fire and smoke.
The QRS Fire Sleeve requires no mechanical fixings or additional framework. Instead, it relies on the integrity of the fire-rated wall construction—whether plasterboard, solid masonry/block, or the QuelStop Fire Batt system—to hold it securely in place. For best performance, penetrations should be cut as tightly as possible to the sleeve itself. Approximate aperture sizes are provided in the Specification Details table below.
The QRS Vent Duct Slim Sleeves 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 Vent Duct Slim Sleeves, and any gaps should be sealed with the QSS QuelStop CE Marked Intumescent Acoustic Acrylic Sealant.
*Please note that custom made items can expect to have longer lead times. Next working day is typical but can depend on outside factors not controlled by Quelfire.
