We use field testing to validate our assumptions. We have all the tools to quantitatively measure the building’s performance, or qualitatively assess the state of construction.
Blower Door Testing For Building Airtightness
Mid-Construction Airtightness Testing
Having a blower door test done before all finished surfaces are installed gives builders a chance to address any areas of air leakage while they are still accessible. It also ensures that projects aiming for a highly airtight envelope are on track to meet their goals.
Thermal Bridging / Air Leakage Identification via Thermal IR Camera
Thermal cameras allow you to capture a snapshot of the thermal radiance of different elements of a building. At 3West, we are trained to use thermal cameras to spot air leakage paths and thermal bridges during mid-construction or post-construction.
Smoke pencils are used to visualize air flows and leakage paths between the interior and exterior environments. Conduct a qualitative assessment of the integrity of the building’s air barrier. For exterior air barriers, large scale smoke machines may be used to indicate leaky connections.
