Description

Intumescent fire collars to prevent the spread of fire through plastic ventilation ducts where they penetrate fire compartment floors.

Consists of a continuous pressed stainless steel flexible shell containing high-performance graphite-based intumescent material which reacts under the influence of heat to exert pressure on the ventilation duct as it softens to form a carbonaceous char, which provides an effective insulation plug thus preventing smoke and fire passing through to the adjoining compartment. The collar has built-in fixing lugs which are used to secure it to the structure.

Features and benefits:

  • Suitable for thin wall polyvinyl chloride (PVC) ventilation ducts.
  • Available for circular and rectangular ducts.
  • Can be retrofitted.
  • Manufactured in the UK.
  • Expected to last the lifetime of the building.

Standards and approvals:

  • Tested to BS EN 1366-3: 2009.
  • CE Marked.
  • Up to four hour fire rating.
  • Performance unaffected by weathering (Type X Durability).

Application/ installation:

  • To be used where a plastic ventilation duct penetrates a fire rated floor. For vertical ductwork, one unit should be installed to the underside of the floor.
  • The soffit of the floor must be smooth and where there are irregularities in the surface, the space between the flange of the unit and floor should be made good using QSS QuelStop CE Marked Intumescent Acoustic Acrylic Sealant (specified separately).
  • The collar should be fed around the plastic ventilation duct, securing the ends together by passing the tongues on one end through the slots on the other end. The tongues should then be bent back and the unit secured to the structure using the integral fixing lugs.
  • The collar must be secured to the floor using fire resistant steel sleeve anchors.
