Associated Materials is proud to celebrate 75 years of innovation!

Associated Materials is a leader in exterior building products for residential and commercial remodeling and new construction markets. We produce vinyl windows, vinyl and composite siding and accessories, and metal building products—and distribute other essential building products to ensure customers find everything they need for their exterior.

Our legacy goes back to the inception of Alside in 1947, and we’ve since expanded our family of industry-leading brands to also include Gentek, Alpine and Preservation. Because of our unique vertical integration of manufacturing capabilities, installation services and distribution locations, we are a true partner with contractors, remodelers, builders and architects for building products and services.

With headquarters in Cuyahoga Falls, Ohio, Associated Materials has been building products better for more than 75 years.
