TPO and Butynol are both established membrane roofing options in New Zealand. The best choice depends on the roof design, substrate, detailing, access, project requirements and the system specified for the building.
TPO
TPO is a single-ply membrane with heat-welded seams. It is commonly used for residential and commercial applications where a continuous waterproofing layer and detailed welded joints are required.
Butynol
Butynol is a flexible synthetic rubber membrane widely used in New Zealand roofing and waterproofing. Correct preparation and detailing are essential to a long-lasting installation.
So which is better?
There is no single answer for every roof. A roofing specialist should assess the building and recommend the system that suits the design and installation requirements.
