We hear about better building performance through air tightness all the time. You’ve probably heard you can test for it with a blower door. But if that’s what you want, how do you get it? Here’s some guidance on how to specify for air tightness and a test to prove it. 

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? 

In this article, I’m tackling real-estate adverts, renovation by paint, and discussing one area of cost for whole-house renovation and the connection between health and wealth.

Common themes with comfortable high performance houses are insulation, airtightness, ventilation and heating. 

Protecting structure from moisture before, during and after construction is a code minimum requirement of B2 durability.

How do I get my design to meet expectations of comfort?
