Fire and smoke stop blocks for apertures in buildings, especially the flutes of trapezoidal formwork.
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.
