Uncontrolled ventilation from buildings can account for up to 40% of a building's heating energy losses
Our ATTMA Certified testing experts can perform air permeability tests to provide test certificates for new builds and diagnosis reports for retrofit
Why use a blower door test?
There are two types of uncontrolled ventilation losses that come from building:
Infiltration Losses
These occur when the wind blows
Buoyancy losses
These occur even when there's no wind, if warm air can escape from the top of the building, cold air will be drawn into the building.
The cost of a test varies depending on whether the building is a new-build, or a retrofit, whether there are existing drawings of the building and whether you want the optional leak detection service.

Note: Existing Whole House Retrofit clients can expect cheaper testing costs if delivered as part of a retrofit project
