From 2003, Approved Document E states that all new UK builds must undergo pre-completion sound insulation testing. New builds must achieve impact sound test results of no more than 62dB L’nTw and airborne sound loss of no less than 45dB DnTw+Ctr. Converted properties must achieve impact results of 64dB L’nTw or lower and airborne sound loss of no less than 43dB DnTw+Ctr. Approved Document E sets out details pertaining to the resistance to the passage of sound.
This Approved Document, as part of UK Building Regulations helps to ensure that newly built or converted houses and residencies, flats and residential spaces and other relevant buildings are constructed to minimum standards that provide ‘reasonable resistance to sound from other parts of the same building and from adjacent buildings.’ All of our tests are fully compliant with Approved Document E and our expert team have been carrying out compliant tests for many years, for thousands of satisfied customers throughout the UK.
