Roofing manufacturer Permavent’s PERMAFLEX has been officially certified by the BBA.
The accreditation confirms PERMAFLEX’s durability, weather resistance, and long-term stability across a wide range of applications, including Solar Panel installations and detailing around complex roof interfaces.
As an accredited solution, PERMAFLEX gives contractors and specifiers an easy-to-install product that removes the challenges associated with traditional lead while delivering consistent, certified performance.
Sales director Martyn Halliwell said: “Achieving BBA certification is a major milestone for PERMAFLEX. It validates the product’s technical integrity and gives our customers total confidence in choosing a safer, easier-to-install lead alternative that performs across a wide range of applications.”
