Siderise TW-P Firestops for Profiled Decks

Siderise TW-PP fire stops are factory produced trapezoidal blocks which are shaped to close tolerances directly from a base mineral wool slab. The product provides a simple fire-rated 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 any nominated cavity of fixed dimensions. 

Siderise TW-PP is available in set widths corresponding to the required fire rating. The major and minor dimensions are matched to the quoted internal dimensions of the profile. 

The material is cut to be nominally oversized in depth relative to the depth of the profile so as to ensure a tight compressive fit within the void.  

Should a smoke resisting seal be required then the TW-PP must be coated with Siderise fire & acoustic gap sealant (or Siderise  TW-PS should be used). 

The Siderise  TW Fillet Blocks comprise of small section rectangular blocks of semi-rigid mineral fibre for a compressed installation within quoted metal decks. 

They are typically used to complement trapezoidal blocks as a double layer method of fire stopping holorib or dovetail deck profiles. 

The trapezoidal Siderise  TW-PP blocks are available to suit all metal decks and profiled cladding. Through a close working relationship with profile deck manufacturers, Siderise has built up an extensive database of profile types, facilitating specification and ordering. The profile reference or name of the deck can therefore be supplied at the point of enquiry to ensure the best solution for the project is selected. 

A Class A1 rated foil-faced version of the product is also available, referred to as Siderise TW-PS. This product 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.
