airtightness / blower-door
What your airtightness number actually means
Airtightness is more than a score. Here’s how to interpret it and how to use it to make real improvements.
Diagnostics
Airtightness Testing
Blower door testing to quantify leakage and support airtightness decisions across Alberta.
A blower door test gives you a measured leakage result under controlled pressure conditions. That is useful when you want a number, but it is even more useful when you want a clearer next step.
Useful for
- comfort investigations
- envelope corrections
- airtightness target planning
- documentation packages
What we provide
- a result summary
- notes on the test context and assumptions
- actionable findings when diagnostic modes are used
Good timing
- before finishes close access points
- when drafts or comfort complaints need evidence
- when attached-building context affects interpretation
FAQ
Can airtightness be improved after finishes?
Often yes, but it is usually easier before the work is buried.
Do attached buildings test the same as detached homes?
No. Geometry and adjacency change how the result should be read.
