Part E – Your Guide to the New Acoustics Regulations 2003


The New Approved Document E, 2003 Edition was implemented on 1st July 2003.

This will apply to houses, flats, schools, hotel and hostel types of accommodation constructed as new build or formed by material change of use.

For new houses & flats only, pre completion testing has been postponed until 1st January 2004.

This solutions guide provides examples of constructions including Rockwool and Rockfon products that meet the requirements of the New Approved Document E (ADE).

The guide should be used in conjunction with Approved Document E, and due attention be paid to the flanking noise and other requirements outlined therein.

In all cases, good design and installation practice should be followed. It is imperative that measures to eliminate or minimise flanking sound transmission are considered at the design stage and that products are installed correctly by the builder.

Failure to do so may lead to limitation of acoustic performance and the requirements of the Building Regulations not being met.

The New Approved Document E provides advice with respect to flanking details, and the appropriate Rockwool gap filling, joint sealing, fire stopping and cavity closing products to achieve compliance are detailed within this guide.

It is anticipated that Approved Document E will be amended from 1st January 2004 to allow Robust Standard Details (RSD’S) to be used for new build wall and floor applications.

The House Builders Federation has commissioned a programme of field testing to establish a set of robust constructions. Rockwool Limited is actively involved in this programme. Compliance with the proposed RSD’s will negate the requirement for pre-completion testing of new build constructions. The Proposed RSD’s are based upon meeting sound test values in excess of those required by Approved Document E. This guide will highlight proposals for RSD’s involving Rockwool products.
