From humble beginnings, more than 100 years later, it is now a global conglomerate with operations in more than 80 countries worldwide.
It is renowned worldwide for its quality and groundbreaking products.
History of Sarnafil
In 1962, a Swiss company called Sarna developed a new thermoplastic waterproofing membrane to replace the traditional multi-layer bitumen roofing system. In 1964 Lausanne Expo, this newly introduced membrane was successfully applied by an architect on the Expo’s large tent-like pavilions. This exposition introduced Sarnafil membrane to building professionals throughout the world. With its proven quality in the past more than 50 years, Sarnafil G|S membranes and systems has provided reliable roofing for many different buildings.
As the inventor of thermoplastic membrane, Sarnafil takes a leading position in this market. Sarnafil G|S PVC membranes, with its fabric reinforcement, hot air weldability, fire resistance, self-cleaning surface coating and outstanding weather resistance, is a premier product, with the longest application history in the field of single-ply roofing industry.
Sika, a Swiss conglomerate, acquired Sarnafil in 2005 and consequently, Sarnafil became part of the Sika Group.
Sarnafil® roofing systems are supplied as one of Sika’s product ranges by Sika local organizations worldwide in more than 70 countries.
