TPO roof system is sure thing

CARLISLE Construction Materials is launching the company’s TPO roofing system across all its European markets, including the UK.

TPO (thermoplastic polyolefin) is a single-ply roofing membrane, said to provide an ‘excellent’ choice for larger flat roof buildings.

Carlisle’s Sure-Weld TPO roofing membrane has been a popular single-ply system in the USA for over 20 years, with more than 500 million m2 installed on buildings worldwide, including factories, warehouses, hospitals, schools and large retail units.

Suitable for both new build and refurbishment projects, the system is available in either white or grey, reflecting rather than absorbing heat. This is said to make it particularly useful for reducing urban heat island effect in heavily developed locations and areas affected by increased temperatures due to climate change. The membrane is also compatible for solar PV installations.

Sure-Weld TPO is removeable and recyclable at the end of its service life.

Allen Coldrake, director of sales and technical roofing at Carlisle, said, “The use of TPO membranes is growing across Europe, with environmentally focused brands using TPO to maximise the potential of solar energy as part of their carbon reduction strategies. In Germany, a ban on PVC membrane in some cities, such as Berlin for example, is acting as a catalyst for growth in the TPO market, while in Spain, high levels of UV and a trend for large roof sizes is also prompting high demand for TPO.”
