How to achieve good levels of airtightness in masonry homes

Publisher:MPA The Concrete Centre

This guide gives an introduction to the topics of airtightness and air leakage and discusses the basic principles of airtightness. It also illustrates a number of areas within masonry construction that may contribute to air leakage and identifies ways in which air permeability of less than 5 m3/(h.m2) @ 50Pa could be consistently achieved in typical UK volume housing.
