Unravelling airtightness

Cowlin, F.

Unravelling airtightness - 2002 - Building Control (135) November 2002, 4-5(2) .

Overview of what is required under the new Building Regulations Approved Document L2 (2002 Edition) which came into force on 1 April 2002. These mean new buildings with excessive air leakage will no longer be acceptable. All new commercial and public buildings over 1 000sq m must be designed, constructed and tested for airtightness. Itemises what to look for when inspecting a new building, and gives guidance on the design of air barriers. Concludes that at present over 50% of buildings would fail to comply with Part L, but suggests total compliance can be achieved by bearing in mind the issue of airtightness at all stages of the building process.
