Application

Fire stop solution for sealing the junction between the tops of compartment walls and the underside of profiled decking. 

Description

Fire stop solution to seal the junction between the tops of compartment walls and the underside of profiled decking. Fire and smoke stop blocks are factory produced trapezoidal blocks which are shaped to close tolerances directly from a base mineral wool slab.


The product provides a simple resilient 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.


TW-PS is a Class A1 rated foil-faced version of the product. 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.


Features and benefits:

  • Up to 120 minutes fire resistance.
  • Fire and smoke barrier.
  • Additionally offers noise reduction.
  • Custom profiles possible.
