The Torch-On Membrane System comprises of two layers – a base sheet that serves as the primary waterproofing layer and a cap sheet installed on top. This serves as a secondary waterproofing layer and also provides the necessary UV protection. These layers are applied with a gas flame that melts the underside of the membrane onto the surface below. Installed on flat roofs; under floating decks and in gutters, this proven method of waterproofing has been serving the New Zealand construction sector well for over five decades.
Ceramic Chip Finish two-layer Torch-On systems exposed to the sun have a ceramic chip cap sheet. This ceramic chip provides the following improvements over traditional slate mineral chip surfaces:
- stronger UV resistance
- a more robust surface
- less chip loss
- less colour fade
- an aesthetically superior and more uniform finish
