Quantify and Qualify

Sika roofing's vinyl 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 recent 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.
