Building envelope airtightness testing (blower door test)

Building envelope airtightness testing (blower door test)

We test the airtightness of building envelopes with the blower door test, the standard method for measuring how well a building is sealed.
The test reveals unwanted air leaks, which cause energy losses and lower a building's energy efficiency.
Our service pinpoints the problems so owners can take the right steps to improve the seal and cut energy losses.
