Application

  • Composite flooring profiles.
  • Dovetail composite flooring profiles.
  • Roofing and cladding.
  • Designed for use in metal decking, typically at the head of a wall.
  • Can be used at the head of a partition, if the head track is fastened to the metal deck, but should be approved by a Fire Engineer or Building Control.

Description

AIM Fire Stop Blocks are made from high density Rockwool stone wool. Incorporated into the building during construction, they are used to seal apertures and are permanently held in place by compression. They can also be used within metal cladding as a firebreak and to protect the top flange of steel beams.


AIM Fire Stop Blocks are predominantly supplied as trapezoidal sections. Square cut, rectangular or round sections are also available.
