Airtightness in a nutshell
Designers and contractors need to know exactly what is required of them under Part L2 of the Building Regulations, which came into effect at the beginning of April 2002. BRE's guide Achieving airtightness provides this information in a nutshell, describing clearly and succinctly the key issues and the roles and responsibilities of the different parties. Sections include: a brief explanation of what air leakage is; essential steps to achieving airtightness; recommended air leakage standards by building type; airtightness terminology; sources of additional information and how BRE can help you to test for and achieve airtightness.

The guide is free and is available from BRE now. Call 01923 664500 for your copy or e-mail cowlinf@bre.co.uk.


Publications

Airtightness in commercial and public buildings
This new report from BRE addresses the increasing awareness of the importance of airtightness in commercial and public buildings. It supports the requirements on airtightness as specified in Approved Document L2 (2002 edition) of the Building Regulations. It is an outline guide to design, setting out the principles of providing an effective airtightness layer and advising on some common pitfalls. It covers:
• the mechanics that cause air infiltration and the benefits that result from increasing the airtightness of a building
• how to design and specify for airtightness
• site practice for airtight construction and testing a building to ensure that it meets the required standard.

The report costs £50 and is available from the BRE Bookshop.
