Competitive Weather Testing Confirms Duradek’s Superior Performance

Duradek, the most tested vinyl membrane on the market, extended its dedication to performance testing by contracting the services of a 3rd-party testing agency to conduct accelerated weather tests with Duradek vinyl and the vinyl of an alternate supplier that has been emphasizing their tough, scuff resistant clear topcoat/film.

The results speak for themselves…
