Wonderbuilds SBS HMP Torch On Underlay

Wonderbuilds SBS HMP Torch On Underlay is SBS polymer modified bitumen torch applied felt. It is also used under Bipol Standard EKP torch on cap sheet. Ideal for use on new roofs and for repairing existing roofs, this can be used on flat and sloping roofs. Also, used as the underlay of a built-up roofing system under the Bipol Standard EKP torch on sheet.

Bicroelast HMP torch-on underlay consists of glass-fibre mat carrier coated with polymer modified bitumen. The upper surface is finished with fine grained-sand and the lower surface has a sacrificial ‘snowflake’ polymer film. This therefore rapidly melts during torching operation. Provides good high temperature performance and is resistant to damage and marking during application.
