Single Ply Roof Membranes

Sika PVC and FPO membranes are manufactured in Switzerland, a country renowned for quality. The production facilities are state of the art, with quality control to ISO 9001 and the membranes are CE marked to BS EN 13956 : 2005. The Swiss production plants also operate OHSAS 18001 Occupational Health and Safety.

The impact on the environment is managed with ISO 14001. Sika membranes also have independent British Board of Agrément (BBA) certification stating life expectancy ‘in excess of 40 years’ for PVC and 25 years for FPO. Sika systems have factory mutual approval.  Sika membranes are dimensionally stable due to their reinforcement, meaning that they do not shrink or lose their shape. They are UV resistant and need no chippings to protect them from the sun’s UV rays. Sika membranes are tested for UV ageing to the highest international standard for waterproofing membranes which requires exposure to 5,000 hours of UV testing. However, we go above and beyond, with our membranes withstanding 10,000 hours of UV exposure.

Alongside this, they have a unique lacquered top coating, providing better resistance to industrial/biological waste and air pollution.  Along with compliance with an ISO 14001 Environmental Management System, Sika Sarnafil membranes have a low environmental impact and when used in conjunction with a high performance thermal insulant can significantly improve the energy performance of a building.
