TORCH ON: Of recent years most suppliers have introduced new cap sheet membrane that are vastly improved and are extremely better than the “older original” membranes. The greater development has seen the chip finish, stone / ceramic chip having a greater UV ability and importantly very little chip loss.
Torch On - Warm Roof: Clearly in the last 10 or so years we have witnessed a huge level of interest and specification for a Warm Roof system. A warm roof system and design has many advantages over existing roofing systems and can be extensively less complicated in construction and costs. Our predominant suppliers are Nuralite, Viking Roof Spec, Equus, Ardex & Allnex.
ARDEX WPM 189+ is a dual-layer, modified bitumen membrane, consisting of a specially formulated bituminous compound. The bottom layer of ARDEX WPM 189+ comprises of an SBS compound which gives high elasticity and excellent flexibility at low temperatures. The top layer is then formed from APP modified bitumen which provides good cold flexibility and high resistance to heat and UV radiation.
TPO: Thermoplastic Polyolefin. Single layer system with added advantage of the wider roll width, up to 3.6mtrs. Complementing the TPO is the Fleece back range, great as an overlay for expired roofs. The Ryno Bond system (TPO) has many advantages as an overlay for expired membrane roofs (see our special projects page)
The recent introduction of new TPO colour range from Viking is very impressive. The Comprehensive “Weldtec” range of membranes from Ardex (made in NZ) has been well received.
