A Better Window Deserves a Better Installation.

Thermoproof combines local manufacturing, advanced window technology, and disciplined installation standards to help your home feel warmer, quieter, and more protected year-round.

The Thermoproof Difference.

A high-performance window is only as good as the installation behind it. The measurement, seal, fit, and finish ultimately dictate how well your home is protected from drafts, moisture, noise, and changing coastal weather.

Thermoproof brings the product and the installation process seamlessly together. Because our factory-trained team understands our windows from the inside out, they follow a disciplined process designed to preserve the comfort, efficiency, and durability engineered into every unit.

Whether you are a homeowner needing a single window replaced or an entire strata complex undergoing a full upgrade, our Installation division delivers precision craftsmanship. We know exactly what it takes to keep out the Island rain and wind—because we live here, too.

Built for Coastal Conditions.

Our products and installation process accounts for the rain, wind, moisture, and seasonal changes that define Island homes.

HPSC Certified Installers

Thermoproof installation teams are certified by the Home Performance Stakeholder Council (HPSC), reinforcing our commitment to energy efficiency, building science, and long-term performance.

Tailored to Your Home and Your Needs.

Every order is configured around your home’s needs — from heat retention and solar control to sound reduction and year-round comfort.

Precision From Initial Measure to Final Trim.

From the initial site visit to manufacturing, installation, and after-sales support, Thermoproof handles every step—giving you complete confidence long after the final trim is in place.

Your Installation Journey

Step 1

In-Home Consultation

We start by listening. Our window experts visit your home to assess your specific needs and environment. Whether you are dealing with moisture issues, outside noise, security concerns, or simply want to keep the heat out in the summer and the warmth in during the winter, we diagnose the problem and map out the right solutions.

Step 2

Transparent Project Proposal

After assessing your home, we return to the office to build your custom proposal. We don't rely on high-pressure pitches or speaking poorly of others to win your business. We let our five decades years of Island manufacturing and craftsmanship speak for themselves, giving you an exact quote and the freedom to decide on your own time.

Step 3

Order Confirmation

Once you approve the proposal, we secure your deposit and lock in your production schedule. Because we manufacture everything right here in Cobble Hill, we proudly offer the fastest order-to-install timeframe on Vancouver Island. Our team maps out a clear timeline so you know exactly when to expect us.

Step 4

Local, Island-Made Manufacturing

Your order goes into production at our state-of-the-art Cobble Hill manufacturing facility. Every window and door is custom-built from scratch and engineered specifically to withstand Vancouver Island’s unique coastal climate using 10-chamber Canadian extrusions, non-corrosive and stainless steel hardware, and Insulated Glass Units featuring Cardinal LoE, argon gas, and SuperSpacer® bar technology

Step 5

HPSC-Certified Installation

Our factory-trained, HPSC-certified crew arrives to install your products with absolute precision. We treat your home with the utmost respect, laying down drop cloths and handling all the heavy lifting. We finish with a meticulous clean-up and a final walkthrough to ensure you are completely thrilled with the results.
