HOUSING AND SOUND INSULATION

Sound or noise transmission may be an everyday occurance and, for some occupants, a series of random and uncontrollable events. This can lead to frustration, anger and stress for occupants. In some cases the persons generating this noise are unaware of the repercussions on their neighbours’ quality of life. One method of addressing noise intrusion from the neighbouring dwelling is to improve the sound insulation.
The purpose of this guide is to provide methods and descriptions of how to improve sound insulation between attached dwellings, to assist in deciding on what levels of sound insulation may be required and to inform on key separating wall and floor types and influences of remedial treatments.
The guidance presented in this document is targeted towards general living noise, where the reason that noise is intrusive due to poor sound insulation of the separating wall or floor. Although some of the treatments may be useful in significantly increasing sound insulation in particular dwellings, they are not designed to deal with noise arising from anti-social behaviour.
Scotland contains 10% of the UK’s housing stock and its wealth of architectural styles, construction methods and design features provide an excellent opportunity to review the sound insulation characteristics of a wide range of dwellings. At least four out of five Scottish dwellings share an adjoining wall with another dwelling and as found in flats, almost two out of every five share a separating floor

SCI P255: Comparison of National Application Documents for Eurocode 3: Part 1.1 and Eurocode 4: Part 1.1

This Technical Report presents a review of the various National Application Documents for Eurocode 3: Part 1.1 and Eurocode 4: Part 1.1 relating to steel and composite construction respectively.
The National Application Documents are produced separately by each country to facilitate the use of the Eurocodes on a trial basis. This report compares, on a clause by clause basis, the requirements such as partial factors, member design, connection details etc. Simple tabular summaries, indicating which Clauses have been modified by each country, are also presented.
