Polymeric Exterior Products Association

The Polymeric Exterior Products Association (PEPA) – formerly the Vinyl Siding Institute – is the trade association representing the wide range of polymeric exterior building and home improvement products used to build resilient, beautiful home exteriors on and around homes across North America. 

Our goal is to create more relevance, value and impact for our products for all those in the value chain. By uniting members across our category, we aim to promote the benefits of exterior polymeric products to the home building industry and drive a more significant impact than ever before.
