Airtightness update 1

Section showing cold air in the cavity
We have an internal cavity wall, due the house having two bedrooms added at the back. I failed to have it filled when we were bashing the house around, but it showed up as the source of a major air leak in our airtightness test. So today we had the cavity filled with polystyrene beads. The sections shows how cold air can infiltrate the house - even without air movement there could be convected heat loss, so we hope this will make a significant difference.(the cavity does connect top to bottom, but this section is through a door)

The boys wer pretty tidy
