Sound Insulation and the Building Regulations

share post tweet

The sound insulation performance requirements as set out in Part E of the Second Schedule to the Building Regulation (1997) are as follows:

E1 (1) A wall which –

(a) separates a dwelling from another dwelling or from another building, or

(b) separates a habitable room within a dwelling from another part of the same building which is not used exclusively with the dwelling, shall have reasonable resistance to airborne sound.

E2 (1) A floor which separates a dwelling from another dwelling, or from another part of the same building which is not used exclusively with the dwelling, shall have reasonable resistance to airborne sound.

E3 (1) A floor above a dwelling which separates it from another dwelling or from another part of the same building which is not used exclusively with the dwelling, shall have reasonable resistance to airborne sound.

The single most important thing to note is the requirement for "reasonable resistance", i.e. the Building Regulations do not contain an absolute performance requirement.
