TPO (thermoplastic polyolefin) membranes, also called single-layer membranes, are composed of a vinyl base. They are often installed on flat roofs and low-slope roofs.
They have a strong resistance to bacteria, algae, fungi and weathering. Furthermore, these membranes are made of recyclable materials and are resistant to ultraviolet rays. However, their soundproofing level is smaller. Therefore the effect of external noise indoors is greater.
This roofing system is recognized for its light weight. Installation can reduce the weight on the roof structure by up to 90 %, which is ideal for the winter climate in Quebec, with its abundant snowfalls.
The remarkable flexibility prevents perforations, tears and damage to the joints, and it can adapt to the natural expansion and contraction of the building.
