Cold bridge detailing

Ultra-low energy refurbs should come with a health warning - you need lots of stamina to keep plodding on!

The insulation has taken longer than anticipated. This is largely because of the "complicated bits" which arise when trying to achieve a refurb at the passive house end of the spectrum. 

Installing a lesser thickness of insulation would normally be quicker and easier, but putting on 2 layers of boarding in most places and being extremely careful at junctions between wall and roof, window and wall, etc takes more time. 

(The greater the insulation thickness, the more any "thin" areas matter - hence places like our eaves junction have taken a lot of effort to achieve what we hope will be a good result).

This week, the boarding is finished and the render coats are well under-way - the end is in sight!

Already, it feels pleasantly warm inside - even with some windows open and no heating system installed. Of course, it should be warm in the house in July - but it has been a rather cold July so far, and it is noticeable that the house is warmer than it was before the insulation went on.
