SIGnature Fire Rated Cap Sheet

The SIGnature Torch On Cap Sheet is a fire retardant formulation, polyester reinforced, SBS, torch applied finishing layer. This cap sheet is utilised on both the 20 and 25 year systems and will achieve an EXT.F.AA fire rating as standard. It is available in two mineral finishes, black or green.

Underlay Options

There are three different underlays that can be utilised within the system and it is this that will dictate the warranty period.

    SIGnature Underlay25
    A polyester carrier, reinforced, SBS, torch applied intermediate or base layer (dependant on specification). Using this underlay option will qualify for a 25 year warranty if used in conjunction with the SIGnature Fire Rated Cap Sheet.

    A glass tissue carrier, reinforced, SBS, torch applied intermediate or base layer (dependant on specification). Using this underlay option will qualify for a 20 year warranty if used in conjunction with the SIGnature Fire Rated Cap Sheet.
    SIGnature UnderlaySA (Self Adhesive)
    SIGnature UnderlaySA is an elastomeric self-adhesive, polyester fabric reinforced underlay. Coated with SBS modified bitumen that has a smooth upper surface that forms an ideal surface for bonding subsequent cap sheets and has a release film backing. Using this underlay option will qualify for a 25 year warranty if used in conjunction with the SIGnature Fire Rated Cap Sheet.

Please note these underlays can be directly applied to a torch receivable Insulation Board only, without the requirement of a venting base layer.
