Siderise TW-P Firestops for Profiled Decks

Siderise TW-P comprises a specifically manufactured low resin content mineral fibre insulation core which is pre-compressed internally and shaped to close dimensions. The material is held in a robust lamella form by the application of reinforced foil to the exposed surfaces to give a Class A1 product.

 The fire stops are factory produced trapezoidal blocks to suit specific decking profiles.. The product provides a simple fire resistant seal to close cavities at the top of compartment walls in conjunction with profiled metal decking, coffered soffits and roofing etc. They are suitable for installation in a cavity of fixed dimensions.

Siderise TW-P is available in set thicknesses corresponding to the required fire resistance performance. The major and minor dimensions are matched to the quoted internal dimensions of the profile.

The material is cut to be nominally oversized in height relative to the height of the profile so as to ensure a tight compressive fit within the void. Where table 1 notes a requirement for compression, this will also be considered at the manufacturing stage. 

The trapezoidal Siderise TW-P blocks are available to suit the most popular metal deck profiles. A CAD file of the metal profile should be provided so that Siderise can investigate the feasibility of manufacturing the trapezoidal block before processing any quote or order request.
