Durabuilt has manufactured windows and doors in Alberta since 1988. Every unit we sell in Calgary is built in our own 280,000 square foot facility, delivered by our own trucks, installed by our own teams and serviced by the same company that made it. When something needs attention in year seven, there is no question about whose product it is or whose installation it was.

Both our sliding and swinging windows are built with a universal design to give you the ability to mix and match these beautiful windows however you want seamlessly!

Common mullion refers to the vertical or horizontal elements that form a division between units of a window. Our sliding and swinging windows have a standard mullion, so you can enjoy combining these windows so you can have more glass and a contemporary look inside and outside!

We bring your vision to life with our creativity, attention to detail, and purposeful innovation. Our industry-leading windows deliver cutting-edge innovations to make life a little easier while giving your home a modern look.

Our triple-pane windows insulate up to 60% more than our dual-pane option, helping to regulate your home’s overall humidity and reduce outside noise. Your home will stay naturally warmer in the winter and cooler in the summer so you can live comfortably, no matter what season it is!
