Thermoproof Windows and Patio Doors

Designed and Built by Islanders

If you live on the Island, there's no escaping it: the sun's rays can cause floors and furniture to fade. Rain, while perfect for our gardens, can do a lot of damage if it gets inside your home. And that lovely ocean mist will try to rust anything it lands on.

Backed by a lifetime warranty, Thermoproof products are built with the Island environment in mind. Since 1977, we have been keeping our Vancouver Island and Gulf Island clients happy. That's a lot of hot summers, buckets of rain, and a mountain of salt thrown at our windows and patio doors.

Bring it on, Mother Nature. We're ready.
