Sean HoodI keep posting my #retrofit stuff to bsky as that seems to be where the other #passivehouse people are but ought to post them here also:
Got my work cut out for the weekend. Bedroom bay window is a stud wall filled with brick off cuts. To be insulated with 160mm of the finest German made woodfibre. New book for if I get bored too. More details in alt text.
Current U-value is ~2.1W/(m²K), will be ~0.22W/(m²K)
From the thermal image, can see how bad the problem is. The detail is showing a horizontal midsection slice, it's also more complex as this is a curved wall. I hope to also insulate the part of the wall between the floor joists too.
