Stricter energy targets are pushing air leakage down to ever-lower levels. Carrying out remediation work and retests when a building fails can be a major headache, leading to delays to the project. This BSRIA guide provides architects, main contractors and subcontractors with a broad base knowledge of how to design and building buildings to achieve their airtightness targets. Aimed primarily at commercial buildings, it gives examples of good and bad practice gathered from BSRIA's 30 years of experience in testing.

Common construction types for walls and roofs are covered, in addition to many of the materials used for penetrations through these elements. The publication also gives guidance on airtightness testing methods, test standards, and the Building Regulations requirements and guidance for testing across the UK and Republic of Ireland.

Contents include:

Specifying airtightness
Composite cladding panels
Structural Insulated Panels (SIPs)
Pipework penetrations
Airtightness testing
The inspection approach
Airtightness diagnostics
Regulatory requirements
Test standards
