Ben Adam-Smith speaks to a wide range of experts about houses and house building. In the process, he learns how inadequate much of Britain’s current housing stock is, and discovers that drastic changes are needed to make our homes more resilient, not just for the present day, but also for an increasingly uncertain future.
A key element in assessing a building’s performance, and an excellent guide to overall build quality, is its airtightness. Many people understand the importance of insulation in reducing heat loss but few realise the more significant role that airtightness plays. In this documentary, Ben follows air leakage expert Paul Jennings from ALDAS as he tests different buildings to see how they perform and how they could be improved.
