Sound Control in Buildings: A Guide to Part E of the Building Regulations
M. W. Simons, J. R. Waters
ISBN: 978-1-4051-1883-5
Paperback
184 pages
January 2004, Wiley-Blackwell
Description
Unwanted noise can be a significant nuisance in buildings, particularly dwellings. Part E of the Building Regulations for England and Wales has therefore introduced substantially improved standards for noise control and stringent new requirements for the testing of completed buildings.
This new book explains the regulations in detail and provides recommendations for good design and construction. It explains those aspects of sound transmission necessary for an understanding of Part E of the Regulations.
Table of contents:
Introduction and background to the regulations; Sound absorption and room acoustics; The principles of airborne sound insulation; The principles of impact sound insulation; Part 2 Approved document E performance requirements; Measurement procedures; Separating walls and their flanking constructions - new buildings; Separating floors and their flanking constructions - new buildings; Dwelling houses and flats formed by material change of use; Internal walls and floors for new buildings; Rooms for residential purposes; Reverberation in common parts of buildings.
Hallmark features:
* Unwanted noise a major problem for domestic property
* Tough new requirements for sound control introduced by new Building Regulations from July 2003
* New testing requirements may mean expensive remedial work for dwellings not up to standard
* This book explains the new regulations in detail and recommends good design and construction methods to ensure compliance
Reviews:
'An excellent accompaniment to professional accoustic consultants and an excellent basis of knowledge for house building industry professionals.'
Building Engineer, June 2004

WinZip 15 introduces a powerful new architecture for increased zipping performance, a streamlined user interface with an innovative, new desktop gadget that makes WinZip even easier to use, major file sharing enhancements, and much more. With this unparalleled functionality and usability, no wonder WinZip is far and away the world’s #1 utility for file compression, encryption, sharing, and data backup.
Performance Architecture
To expand on WinZip’s state-of-the art technology, WinZip 15 incorporates a new architecture designed to enable significant advancements in zipping performance. Enhancements will plug into this framework, dramatically increasing the speed of compression and encryption operations and considerably reducing the time it takes to zip large files and/or large groups of files.
Usability Breakthrough
In addition to evolutions in user interface design, WinZip 15 introduces a revolution in file compression and file sharing with its groundbreaking desktop gadget. This innovative tool is your express portal for key zipping tasks. Now you can zip, unzip, and email files without opening the WinZip application—simply drag files onto the appropriate WinZip Desktop Gadget tab for instant compression, decompression and email capabilities.
Enhanced File Sharing
With a few easy clicks, WinZip 15 lets you zip and encrypt a set of files as an email attachment, compose an accompanying message, and send the email instantly—all directly from the WinZip window, without opening your email application! The result? You save time and unnecessary steps while ensuring that the files you share are smaller, safer, and more manageable.

BS 8204-1 gives recommendations for the design and laying of concrete bases and cementitious levelling screeds to receive in situ floorings. It also gives recommendations for constituent materials, design, work on site, inspection and testing of concrete bases that are to receive in situ wearing screeds.
BS 8204-1 covers the following types of materials:
a) Concrete (see BS 8204-2)
b) Polymer modified cement (see BS 8204-3)
c) Terrazzo (see BS 8204-4)
d) Mastic asphalt (see BS 8204-5)
e) Synthetic resin (see BS 8204-6)
f) Magnesium oxychloride
g) Pumpable self-smoothing screeds (see BS 8204-7)
BS 8204-1includes information on bases and levelling screeds that are to receive flexible floor coverings such as:
h) Textiles
i) Linoleum
j) Polyvinyl chloride
k) Rubber
l) Cork
It also includes rigid floorings such as:
m) Wood block and strip
n) Laminate floor coverings
o) Ceramic tiles
p) Natural stone.
BS 8204-1 applies to ground-supported and suspended concrete floor bases. It includes the use of concrete and levelling screeds made with lightweight aggregates conforming to BS EN 13055-1. Recommended methods for the assessment of levels and surface regularity and for the determination of in situ crushing resistance (soundness) are also given in this standard.
BS 8204-1 does not provide guidance on the structural design or related construction of concrete ground-supported floors or suspended slabs. Information on these aspects is given in BS 8110-1. The specification of concrete for base slabs is given in BS 8500-2. The recommendations in this code of practice relate to those other aspects of design and construction of concrete slabs that affect the performance of the overlying levelling or wearing screed.
This standard has been amended to include updates made to other cement and aggregate standards.

EN 13986:2004 Wood-based panels for use in construction - Characteristics, evaluation
This document defines wood-based panels for use in construction and specifies the relevant characteristics and the appropriate test methods to determine these characteristics for wood-based panels, unfaced, overlaid, veneered or coated:
В· for internal use as structural components in dry conditions ) ;
В· for internal (or protected external) use as structural components in humid conditions ) ;
В· for external use as structural components ) ;
В· for internal use as non-structural components in dry conditions1);
В· for internal (or protected external) uses as non structural components in humid conditions2);
В· for external use as non-structural components3);
В· for use as structural floor decking on joists in dry1) or humid2) or exterior3) conditions;
В· for use as structural roof decking on joists in dry1) or humid2) or exterior3) conditions;
В· for use as structural wall sheathing on studs in dry1) or humid2) or exterior3) conditions.
It provides for the evaluation of conformity and the requirements for marking these products.
This standard covers wood-based panels in the form of solid wood panels, LVL ) , plywood, OSB, particleboards (chipboards) either resin- or cement-bonded, wet process fibreboards (hardboards, medium boards, softboards) and dry process fibreboards (MDF) for use in construction. They may contain chemical agents to improve their reaction to fire and their resistance to biological attack, e.g. by fungi and insects.
This document is not intended to be applicable to wood-based panels for use in non-constructional applications.
