What is an Air Tightness Test?
Air permeability (or airtightness) refers to a building’s ability to retain warm, conditioned air to prevent the entry of cold air from the outside.
The building regulations Part L set a standard target for new dwellings to achieve, with the absolute maximum being a rate of 10m3/(h.m2) of air loss at a pressure of 50pa.
Not only is it a requirement for sign-off, but air leakage can account for a large proportion of heat loss. Therefore, your Facility Managers must ensure your property is as airtight as possible; this will assist in reducing the overall energy costs and help you achieve a better EPC rating.
When is Air Testing Required?
- The formal air tightness test is required upon completion of your build and is a prerequisite to successful EPC lodgement
- Although the formal test is only needed at the end of construction, it is vital to keep airtightness in mind throughout the project
- For this reason, we offer design advice and informal on-site testing so that you can gauge your progress every step of the way
