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 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.
