Southwest Radon offers a service in providing professional airtightness solutions and the installation of airtightness products to maximise the airtightness of your building. The Building Regulations 2011 TGD L Dwellings indicates that reasonable provision for airtightness is to achieve a pressure test result of no worse than 7m3 /(h.m2 )@50Pa. Current good practice for energy efficient dwellings includes achieving airtightness of better than 5m3 /(h.m2 )@50Pa and best practice is less than 3m3 /(h.m2 )@50Pa. The airtightness appropriate for a particular dwelling design will depend upon the Building Energy Rating the builder is aiming to achieve. Care should be taken to ensure compliance with the ventilation requirements and permanent air supply of Part F and of Part J of the Building Regulations respectively. The airtightness appropriate for a particular project will depend on the building energy rating the builder/homeowner/architect is aiming to achieve. The airtightness of a dwelling, or its air permeability, is expressed in terms of air leakage in cubic meters per hour per square metre of the dwelling envelope area when the building is subjected to a differential pressure of 50 Pascals (m3 /(h.m2 )@50Pa).
