July 4, 2005 — Roofing membrane samples from 44 roofs in North America and Europe document the durability of Sarnafils vinyl roofing membranes in exposed applications, according to a study released by Sarnafil Inc., a division of Sarna Group, based in Switzerland. The company is a leading manufacturer of thermoplastic membranes for roofing and waterproofing applications.
The average age of the roofs tested was more than 20 years, with the oldest 34 years in age.
Considering the age and the condition of the roofs analyzed, the data indicate that a properly formulated, properly maintained, reinforced vinyl roof membrane system performs in excess of 20 to 30 years in various climates throughout Europe and North America.
Sarnafil is a subsidiary of Switzerland-based Sarna Group, a manufacturer of high-tech plastic polymers for a wide range of applications including roofing, waterproofing, civil engineering, and automotive applications. For more information, visit the Web site.
