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 an ISO/IEC 17065 accredited certification body 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 and NFPA 268.

To access all published Product Certification Listings (PCLs) and Product Evaluation Reports (PERs), please click here for the public directory.

Products that appear in the directory have met or exceeded all the requirements of ASTM D3679 for vinyl siding, ASTM D7793 for insulated vinyl siding, ASTM D7254 for polypropylene siding, or ASTM D7445 for backed vinyl siding.
