A Defined Airtightness Step for Your Build
Kootenay Airseal gives builders a clear, measurable way to handle airtightness for their projects. Instead of relying solely on extensive manual sealing and hoping targets are met, we complete the air sealing process within your construction schedule and provide documented results for your records.
This creates a defined performance step that supports:
Meeting required airtightness targets under the BC Energy Step Code
Reducing last-minute corrections before inspection
Minimizing the risk of failed blower door testing
Keeping the project moving toward occupancy without added disruption
A Controlled Approach to Air Sealing
Aeroseal is an interior-applied air sealing system designed to reduce air leakage in a measurable way.
Seals from the inside
Targets both visible and hidden gaps
Monitors air leakage reduction in real time

At thinkBright Homes, we’re committed to building and retrofitting homes that are healthier, more comfortable, and built to perform for generations. Partnering with Kootenay AirSeal to integrate AeroSeal envelope technology into our custom homes and deep energy retrofits has helped us significantly reduce air leakage and elevate overall building performance. Because we design homes as integrated systems, airtightness is critical. AeroSeal allows us to achieve measurable improvements in envelope performance, resulting in more stable indoor temperatures, improved indoor air quality, and lower energy use. The process supports our building-science approach by reducing guesswork, improving consistency, and helping us meet the high standards we set for comfort, durability, and energy efficiency. Working with Kootenay AirSeal helps us build resilient, low-carbon homes that tread lightly on the planet while providing long-term value and real-world comfort for our clients.
Paul & Meredith – thinBright Homes – Invermere, BC
“Our multi-stage, medium-density housing project included a complex mix of units for both purchase and rental. The funding model required the rental units to meet higher Step Code levels. Kootenay AirSeal played a crucial role in helping us achieve these targets by applying AeroBarrier and eliminating much of the guesswork from the process. On a busy site with dozens of subcontractors, it’s nearly impossible to track every single building envelope penetration. Kootenay AirSeal’s combination of traditional air sealing and their patented technology took care of both large gaps and small leakage. Their process removed stress, uncertainty, and manual oversight from a critical part of the build.”
Trevor, Project Manager – Generation Homes – Invermere, BC
“We build custom homes in the FortisBC gas service area of the Kootenay Boundary Region, and we work closely with our Energy Advisor to apply for Fortis grants tied to achieving Step 4 and 5 of the BC Step Code. Thanks to Kootenay AirSeal’s patented AeroBarrier technology, we’ve successfully reached these Step Code targets—qualifying for grants of $15,000 and $20,000 per home. These rebates more than cover the cost of Kootenay AirSeal’s services and actually put money back in our pocket as builders. That translates to real cost savings per square foot. Even better, we can reinvest those savings into additional high-efficiency upgrades, such as heat pumps and emerging new technologies in water heating systems. Kootenay AirSeal eliminates the guesswork of meeting high performance standards and makes it easier—and more affordable—to build better homes.”
Dan, Builder – Rossland, BC
“The final blower door test landed this home at Step 5. What Kootenay AirSeal offers is a no-brainer for any builder aiming for Step Code 4 or 5. The cost for their service was equivalent to what I would have paid just for air sealing materials—not including the labour hours we would’ve spent. In fact, we COULD have spent more and still not achieved step 5. This is money well spent for results you can count on.”
Trevor, Builder-Kimberley, BC
Preparing for Today’s Step Code and What’s Next
The BC Energy Step Code continues to advance toward higher performance standards. Airtightness is a required component of compliance and verified through testing.
Planning for airtightness early helps reduce uncertainty later in the build process.
