About Thermoproof

Thermoproof Windows & Doors are a locally owned manufacturer that has been based on Vancouver Island since the late 70's. When you've been around this long you've seen a couple of things come and go. We started out with wood windows, then aluminum, and now vinyl. The components may have changed but the focus on quality has continued. Our 5 core values at Thermoproof are safety, quality, communication, teamwork, and innovation.
