Thermoproof designs and manufactures Vancouver Island window systems. The work is informed by the realities we see here: moisture, wind-driven rain, salt air near the coast, and seasonal temperature swings.
Our lineup is organized into clear series so homeowners and professionals can choose based on performance needs, design intent, and budget.
Not every project needs the same window system. A standard retrofit, a custom home, and a high-performance build have different requirements.
That is why Thermoproof offers multiple window series, each built for a defined use case.
Across the lineup, the approach stays consistent:
Coastal-ready windows configurations designed for wind-driven rain, salt air, and sustained moisture.
Our lineup is organized into four distinct series, allowing homeowners and professionals to select systems based on specific performance targets, architectural intent, and project scope.
A proven uPVC system designed for dependable performance and straightforward installation options.
Common Fit:
Available in common configurations including casement, awning, slider, and fixed, with dual- and triple-pane glazing options.
A premium uPVC series with upgraded hardware, refined profiles, and expanded finish options for projects where appearance and performance both matter.
Common Fit:
A hybrid system combining an aluminum exterior with a uPVC frame. Built for projects that require durability, finish stability, and architectural presentation, especially in exposed coastal areas.
Common Fit:
A tilt-and-turn system designed for clients who want top-tier performance, comfort, and airtightness, with a product that suits North American construction methods. The Fjord Series features a dual-opening mechanism that allows the window to tilt inward at the top for secure ventilation or swing fully inward for easy cleaning and maximum airflow. This versatile functionality improves indoor air quality while maintaining high security and energy efficiency standards.

Thermoproof supports multiple purchase paths. In some regions we sell and manage installation directly. In others, products are supplied through authorized dealers and installation partners.
Either way, the manufacturing standards remain the same, and support stays local.
