After establishing in last month's post that vapour convection is the major contributor to Leaky Building 2.0, we will now explain how to measure installed performance by using a Blower Door.

Following on from last month's topic — thermal bridging — I want to continue with more applied building science, focusing this time on moisture transport.

My new blog on EBOSS is intended to give you an understanding of applied building science relating to moisture control. Every month I will address a variety of building physics facts and discuss their relevance to the New Zealand climate and construction industry.
