Air Tightness Testing.
The air tightness of new houses and flats has a significant effect on energy efficiency and comfort for occupants. Building Regulations set a maximum level of air permeability that must not be exceeded. Technical Standard L lists ways of proving compliance with this requirement, which includes Air Tightness Testing.
AFM can advise on potential leakage issues before testing and can respond quickly to requests for testing. Pre-completion Air Tightness testing in new dwellings is undertaken to confirm that air leakage into or out of new dwellings does not create excess energy use.
