Sika Sarnafil’s thermoplastic PVC membranes have been proven to last for decades on facilities as diverse as high rises, museums, retail stores, sports arenas and schools. We have numerous roofs that are currently over 35 years old – and still performing – proving our ability to pass the test of time.


A study titled "Quantify and Qualify," tested 44 of Sika Sarnafil's oldest roofs throughout the world. The study included testing the physical properties of the samples as well as glass transition temperature and hail impact.

The Roger Center

The Roger Center in Toronto is a good example of the long-lasting durability of Sika Sarnafil's membranes. It was built in 1989 with Sarnafil membrane...and was renwed in 2019, 30 years later. Even after 30 years, the membrane was still performing very well.

The British Board of Agreement, a third party product assessment agency in the UK, also concluded that all available evidence suggests that Sarnafil Roof Membranes have a service life in excess of 35 years, and are engineered to withstand extreme environmental exposure.
