With the introduction of Building Regulations 2003, Document E which limits to a maximum of 64 decibels of impact noise for flats, sound insulation has become an important issue when undertaking a refurbishment or complying with the lease requirements. Sound proofing has become of vital importance ever since homeowners have been successful in modifying leases from carpets only surfaces to wooden floors ones.
There are two basic types of sound pollution that can be diminished through soundproofing, acoustic (airborne noise) and impact.
Acoustic insulation helps protect you and your neighbours, from the airborne sound of voices, music and similar noises travelling through the shallow void space between your floor and your neighbours ceiling.
Impact sound sources produce noise by direct physical excitation of a part of a building, for example footsteps on a floor, the source induces vibration of a solid construction which in turn creates air vibrations. Impact sound insulation is concerned with resisting this impact sound upon separating floors.
A timber floor transmits approximately 75 decibels of impact noise, hence the need for an impact sound reducing product. The good news is that engineered wood, have a relatively resilient core material, which is generally a good absorber of impact noise.
Walking on Wood uses several approved impact soundproofing products, but recommends Accorub® because it offers excellent quality relative to its cost, consistently reducing impact sound to approximately 42 decibels – well below the regulations.
Depending on the existing construction and floor finish will help determine which materials and systems you should use, below are some examples to help you decide which one suits your requirements. For further information’s come and visit us at our showrooms in central London.
