Hi,
Insulated under ground floor in 1890 house, from crawl space, by putting space blanket between all joists.
Now the awkward bits; the small gaps between wall and joist (4-6cm) and also the joist structure around fireplace.
I saw a suggestion here to fill the gap between wall and joist with expanding foam. However, expanding foam doesn't work very well when being sprayed upwards, as the can can't be held upright.
Had a go today. Got very little foam out of the can. A lot of it fell out onto ground.
Any ideas how to fill the space from underneath?
Thanks.
