Blower Door Testing
Measure how much uncontrolled air moves through a building enclosure and find opportunities to improve airtightness.
ABOUT THE SERVICE
Clear information for better project decisions.
A blower door test uses a calibrated fan to create a controlled pressure difference across the building enclosure. The measured airflow provides an indication of overall airtightness and can help locate leakage or verify performance at different stages of a project.
What this service includes
- Preparation of the building for the test
- Installation and operation of calibrated testing equipment
- Airtightness measurements under controlled pressure
- A summary of the test result and relevant observations
Who this service is for
- Homeowners investigating drafts or air leakage
- Builders checking airtightness during construction
- Renovation projects evaluating enclosure improvements
- Projects that need measured airtightness information
