Introducing PEPA | Exteriors For A Resilient Future

We are the Polymeric Exterior Products Association (PEPA), the trade association representing the wide range of polymeric exterior building and home improvement products used on and around homes across North America.
As the Vinyl Siding Institute since 1978, we have helped champion the benefits of resilient, beautiful siding. As our category has evolved, so has the demand for more varied architectural products with those same performance and aesthetic features. That’s why we are shifting from a singularly focused siding association to one that represents the growing category of polymeric building products used across the entire home exterior.
Now we’re ready to show the world the power of polymeric products. Together we can unleash new opportunities for our category-because there are simply no limits to what can be done with polymeric exterior products.
