About Us

Keystone Window Films has been a Pittsburgh-based, family owned and operated window film installation business since 1959. Our experienced window film installers can help protect your office, your home AND your vehicle.

Originally founded as Solar Screen of Pittsburgh, Keystone Window Films has grown to became a recognized leader in commercial, residential, and automotive window film installation services in the Pittsburgh area and beyond.  As window film technology evolved, Solar Screen advanced beyond the company’s initial focus on automotive window tinting services to become an innovative leader in commercial window film installation services and residential window film installation services … working with clients to solve a wide range of security, privacy and decorative window film needs.

This increasingly broad use of protective window films to solve critical, high value applications was the basis for rebranding the company in 2019, our 60^th anniversary!  Today, Keystone Window Films is a trusted window film installation leader, offering hands-on management, highly-trained window film installers, quality window film materials and state-of-the-art digital film cutting technologies to help our client’s achieve their protection, durability and aesthetics challenges.  Our experienced application experts work closely with clients using a consultative method to understand their requirements and develop the best window film solution for each unique project.
