Week 55, Day 4:

• Another attempt at the air tightness testing, more with a view to understanding where the air is leaking and how much is going through the sliding doors than in expecting to pass the test
• By running comparative tests with the doors taped up and then without, it looks like the doors are contributing roughly 0.17 to the overall air leakage
  • That’s for the four Internorm HS330 sliding doors and one badly-adjusted hinged door which has a gap at one corner
• Even with the doors taped up there’s still a significant leak somewhere, which is showing up in one of the bathrooms and also behind the false wall in the Living Room
• The plan now is to hire an uncalibrated Blower Door and use that to apply pressure while eliminating as many leaks as possible, then commissioning another test (which will hopefully be successful)
