Thermoproof Vinyl Windows

We use Thermoproof dual-pane windows and in our home improvement projects. They offer superior structural quality, efficiency and safety. They are available in polyvinyl chloride or modern, high-quality coated aluminum with extras like optional brass internal grids.

They are available in a variety of styles and custom-sized for your home. The 2 layers of glass may also be Sungate 500 Low-E, coated with Solarbronze or Azurlite, or filled with Argon gas. Sliding vinyl windows have Positive Cam Locking systems, secondary "night" locks, and an anti-lift mechanism that keeps the windows from being lifted out of their channels from the outside. Sliding doors have a dual steel pin, spring loaded secondary lock that is foot operated for ease and additional security.

A Bay Greenhouse model is available and windows can be created in custom shapes, sizes, and materials.

Thermoproof windows are manufactured in Chemainus, BC, visit the Thermoproof web site.
