VSI Product
Certification Program

The Polymeric Exterior Products Association (PEPA) owns the VSI Product Certification Program; the Program is an independent third-party certification program with multiple ISO/IEC 17065 accredited certification bodies in place.

The Program offers two options for reporting through a Product Certification Listing (PCL) or Product Evaluation Report (PER). In addition to the ASTM product standards, the Program recognizes standards such as ASTM E84, ASTM E119, NFPA 268 and the National Building Code of Canada (NBC).

To access published Product Certification Listings (PCLs) and Product Evaluation Reports (PERs), please reference Interek and ICC-ES.
