AD Systems

    The AD Systems concept began in 2009, originally designed as an interior storefront configuration for commercial projects concerned with acoustical mitigation and space savings. This “office front” solution was tailored to the needs of higher end corporate clientele where customized design features were desired, such as roller blinds and synchronized double doors.


    In 1974, Chem-Pruf founder William V. Pitt designed, engineered and built the first successful industrial fiberglass door that would not bow, rack or warp. This remarkable door was made possible by a unique, now patented, one-piece fiberglass stile and rail system. Tough, corrosion-resistant fiberglass door plates which form the faces of the door were permanently bonded to the stile and rail to create the finished corrosion resistant door. With an idea, a feat of engineering and a wealth of manufacturing know-how, Bill Pitt founded not only Chem-Pruf Door Company but an entire industry.
