Durable Frames

The durable vinyl frames on sliding patio doors don’t absorb moisture and you don’t need to paint them, leaving you more time to enjoy the Okanagan.


One size doesn’t fit all. Sliding patio doors are available in two-, three-, or four-panel configurations. What style best suits your home? 

Natural Light

Enjoy more of the beautiful Okanagan sky and natural light thanks to the more-glass and less-frame style of our sliding patio doors.

Best Use of Space

If you’re short on space or want extra room in your home, a sliding patio door is perfect because it offers more space than standard doors.


We believe in the quality of our patio doors so much that we offer lifetime warranty on all of our products through the manufacturer. We’ll even register for you!
