AIM Fire Stop Blocks

AIM High Density Rockwool stone wool Fire and Smoke Stop Blocks for apertures in buildings, especially the flutes of metal profiles

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 permanently held in place by compression. They can also be used within metal cladding as a fire break and to protect the top flange of steel beams which are not connected to concrete floor slabs by stud connectors.

Applications

• Composite Flooring Profiles
• Dovetail Composite Flooring Profiles
• Metal Decking, Roofing and Cladding
• Tested to BS 476 part 20 and assessed by Warrington Fire Research Centre

Fire Performance

Length measures the amount of fire stop material required. The total length may be provided by two shorter blocks (i.e. two 50mm long blocks are suitable for a minimum length requirement of 100mm).

Acoustic Rating

When installed above a partition and where an imperforate 12.5mm plasterboard ceiling is installed to abut the partition below on both sides, the room to room sound reduction, on the path of the Fire Stop Block, will be at least 47dB – average sound reduction index.

Installation

AIM Fire Stop Blocks are push fitted into place; they must fit tightly and completely. Dovetail fire stops are supplied as rectangular blocks, which are pinch fitted into the profile, then pushed into place. Slip plates may be used for difficult installations.
