Application

Intumescent vent duct fire sleeves to prevent the spread of fire, where either rectangular or circular plastic plastic ducts penetrate fire compartment walls.

Description

The QRS Fire Sleeve consists of a continuous pressed steel shell containing a high performance graphite based intumescent material which reacts under the influence of heat to exert pressure on the plastic vent duct as it softens to form a carbonaceous char which provides an effective insulation plug thus preventing fire passing through to the adjoining compartment.


The QRS is manufactured specifically to suit differing sizes and diameters of duct and is supplied ready to be fitted into the wall with an opening lid for retrofitting.


Durability

Tested to Type X durability which means the QRS Intumescent Fire Sleeves can be installed in conditions exposed to weathering.


Features and benefits:

  • Suitable for masonry walls or plasterboard partitions
  • Suitable for insulated and non-insulated partitions
  • Can be retrofitted
  • No mechanical fixings required
  • Robust galvanised steel shell
  • Can be installed as a cluster with multiple ducts
  • Can be installed in conjunction with the QuelStop Fire Batt system
  • Manufactured in the UK
  • Expected to last the lifetime of the building


Standards and approvals:

  • Up to two hour fire rating
  • Tested to BS EN 1366-3
  • Classified according to EN 13501-2
  • Tested with Uncapped / Uncapped (U/U) duct configurations as required for ventilation ducts
  • CE Marked (QRS75; QRS110/ 54; QRS205/ 60; QRS220/ 90)
  • Performance unaffected by weathering (Type X Durability)


Installation:

Quelfire QRS CE Marked Intumescent Fire Sleeves should be used where a plastic ventilation duct penetrates a fire rated wall to maintain the compartmentation in the event of a fire.


The QRS requires no mechanical fixing or framework support, they rely on the fire rated wall construction, plasterboard or solid masonry/block (or QuelStop Fire Batt) to hold it in place so the penetrations should be cut as tight as possible to the QRS Fire Sleeve itself, suggested approximate apertures sizes are given in the “performance” table in the associated "Product Data Sheet".


For the simplest installation, the QRS Fire Sleeve should be installed around the duct and then the wall installed tight around the QRS, however, they can be retrofitted into the wall too.


Simply hinge open the lid, feed around the duct, wrap tight and close the lid, secure shut with the self-adhesive tape supplied (or self tapping screw in the case of circular fire sleeves) and then slide the QRS along the duct into the wall construction.


The QRS should be installed centrally positioned within the wall and must be either flush or protruding from both sides of the wall in accordance with the relevant installation detail.


Once installed into the wall, in the correct position, the perimeter should be sealed with QuelStop Intumescent Acoustic Acrylic Sealant.


Where oversize hole or letterboxes with other services are formed then the QRS Fire Sleeve can be installed in conjunction with the QuelStop Fire Batt system having been tested in various wall constructions including with multiple ducts/QRS stacked or side by side.


Where a cluster of ducts/QRS are installed the QRS should be tight to each other, alternatively they need to be far enough apart to suitably install QuelStop Fire Batt or the original wall construction, all in accordance with the specific installation detail and tested scope of application.


A full set of installation details and a step by step guide are available and we recommend you check all available data before commencing installation.


For full details of the tested scope of application and for installation details, please refer to the associated document "Installation Instructions".
