Why is Air Tightness So Important?
Air tightness is an important element of building regulations in the UK. Testing air tightness in new properties, as per Part L of UK Building Regulations can make a big difference to the energy efficiency of properties as well as how comfortable and well-heated they are for occupants. Better standards of air tightness will mean that there is less air leakage occurring, which in turn will make for a more robust building envelope and better heat retention and energy efficiency.
