Sika Sarnafil celebrates the 50th anniversary of the Sarnafil brand roof membrane

An architect at EXPO 64 in Lausanne, Switzerland, realized that he could use the new tear-resistant material Sika Sarnafil as the roof for the large tent-like pavilions at the Expo.

“Sarnafil’s biggest selling point is their track record,” said Justin Harris, owner representative for the Alpine School District in Lindon, Utah.

Sika Sarnafil, the global leader in thermoplastic roofing and waterproofing systems, is celebrating 50 years of the Sarnafil® branded membrane, the world’s first reinforced thermoplastic commercial roofing membrane, known today for its proven performance over time.

In 1962, chemists from the four-year Sarna Company introduced the Sarnafil membrane on a series of test rooftops. Shortly afterwards, an architect at EXPO 64 in Lausanne realized that he could use the new tear-resistant material as a roof for the large, tent-like pavilions at the Expo. At this exhibition, the young company became known to construction professionals all over the world.

Since then, the company has made more than 15 billion square feet of thermoplastic membranes – enough to cover both New York City and Chicago.

“Sarnafil membranes have consistently set the bar for high quality in the roofing industry,” said Brian J. Whelan, Sika Sarnafil senior vice president. “Renowned international organizations such as the British Board of Agrément and the Army Corps of Engineers, as well as independent research by roofing experts, have consistently ranked Sarnafil membranes among the best in the industry. Equally important is that the Sarnafil membrane continues to perform well, reassuring builders and builders that they are choosing a membrane with 50 years of proven performance around the world. “

In 1975, Sarnafil, Inc. was founded in Canton, MA and Mississauga, Ontario. The first US installation of a Sarnafil roof system in the US was completed the following year at the First United Methodist Church in Laconia, NH.

Sarnafil is known for its proven performance over time and known for innovating in the industry:

Sika Sarnafil milestone innovations

  • Waterproof protection: The automatic hot air seam welder Sarnamatic was developed in 1966, which welds membrane overlaps to ensure waterproof protection
  • Green Roofs: The first green green roof to be protected by Sika Sarnafil’s G476 waterproofing membrane installed at Phillips Exeter Academy in Exeter, NH in 1978
  • Custom Color Membrane: Introduced Custom Color Roof Membrane and Acrylic Coating in 1979
  • Recycling: Introduction of the SarnaPad Roof Walkway Mat from recycled membrane production waste and scrap in 1994. In 2008, Sika Sarnafil introduced a take-back and recycling program for aged PVC roofing membranes, with which building owners can minimize the enormous amount of waste in landfills nationwide
  • Energy efficiency: Introduction of the EnergySmart Roof® system’s reflective membranes, which in 1998 exceeded the requirements for cooling roofs from ENERGY STAR, California’s LEED building energy code and Green Globes
  • Proven Performance: In 2001, Sarnafil collected roofing membrane samples from 44 roofs in North America and Europe and the durability of the company’s vinyl roofing membranes in exposed applications was documented. The average age of the roofs tested was more than 20 years, the oldest being 34 years. In 2008 the British Board of Agrément carried out an independent analysis of Sarnafil roofing membranes and certified: “All available evidence suggests that Sarnafil membranes have a lifespan of more than 35 years when used according to the relevant BBA certificates should. ”

“Sarnafil’s biggest selling point is their track record,” said Justin Harris, owner representative for the Alpine School District in Lindon, Utah. “We walked on several Sarnafil rooftops over 25 years old in the Utah area – and it was amazing to see the condition firsthand. If necessary, you can still weld the old membrane on. The durability has proven itself in practice, not just in the test laboratory. “
