This article is the second in a series looking at thermal upgrades to single-leaf walls of existing houses. It compares a range of ways of upgrading masonry single-leaf walls, particularly the ubiquitous hollow block wall, and the impact of those decisions on moisture content, wind- and airtightness, cost and heating. Future articles will look at various drylining approaches for a range of walls including brick walls of various widths.
