Airtightness testing was introduced for dwellings and non-dwellings in Section 6 of the Building Standards for Scotland on 1st October 2010. Mandatory testing will be phased in during 2011.

This guide explains the new Standards and gives practical tips on how to ensure your buildings pass. It is of relevance to anyone involved in the building process needing to know about airtightness, from architect and consulting engineer, to project manager and contractor.

Airtightness is a vital component of sustainable design. A leaky building will suffer poor control, draughty conditions and in all likelihood, excessive energy consumption for heating and cooling. Buildings that are not airtight will cause their mechanical ventilation and air conditioning systems to struggle to maintain comfort conditions.

Airtightness is a legal requirement. Follow the rules explained in this guide and you won't go wrong.
