A practical guide to building airtight dwellings

Share this Post:

This guide from the United Kingdom, which has been jointly produced by the NHBC Foundation and the Zero Carbon Hub, brings together the experiences of those who have already got to grips with airtightness for the benefit of designers and builders who have not. It identifies the common air leakage paths in typical constructions and provides practical advice on how these can be addressed. It stresses the importance of designing in an air barrier and ensuring that its integrity is maintained throughout the construction phase.
