Warm Roofs from Waterproofing Systems - Waterproofing Systems warm roof system is a roof which has the insulation installed above the structure with a waterproofing membrane installed directly over the insulation. The system is designed to keep cold or hot external climatic conditions isolated while the insulation system ensures warm or cool temperatures as desired inside the building. The R value must be calculated to ensure the correct insulation thickness is specified along with the calculation for the dew point (both important factors).

Waterproofing Systems specifies Koolfoam Black Pearl Noepor insulation panels as part of the warm roof system.

Waterproofing Systems recommends Bituflame Torch On or duroTUF TPO systems for our Warm Roof membrane systems. Venting is essential to ensure air equalisation within the roof space. This will reduce pressure on the roof substrate and vent moisture out of the roof cavity. We recommend using a combination of exposed roof vents and secret venting through the soffits.

The duroTUF TPO membrane system complies with the NZBC as an alternative solution and is BRANZ appraised (950) to be used on roofs and decks.

The duroTUF TPO formulation was developed to allow for extreme pliability, flexibility and weldability during installation. Along with such installation advantages, our TPO’s state-of-the-art formulation helps our product to resist extreme weather conditions, including ultraviolet radiation and high surface temperatures

duroTUF TPO is a suitable substrate for timber raft systems, tileJAKs and when used with the ABS Schluter 25 uncoupling system. A ceramic tiled finish can be achieved making duroTUF TPO a very good product selection. The in service history of TPO membranes in New Zealand is now 13 years without any issues.
