Westech History

Building a Reputation for Consistent Excellence

Westech ULC began extruding custom shapes for the window and door industry in 1979 as Engineered Profiles Ltd. In 1983, the first fully welded casement window system was designed and offered to window fabricators. As the market conditions dictated new systems were added to meet the growing demands for maintenance-free, energy-efficient, vinyl windows.

 

The window division now operates under the Westech Building Products, a Westlake Chemical company.
