This month we look at 'airtight' vs 'breathable' building. Is it possible to achieve both within the same build? 

We pipe water inside buildings, so what happens when we turn it into steam?

A look at how a peel and stick weathertightness membrane performs in a fire when used as a temporary cladding.

Why strapping and lining masonry walls on the inside is not a good idea, not for renovation, not for new builds. 

How can we safely add insulation to existing walls without risking trapped moisture and compromising durability?
