Hi there. I've been lurking here for a long time as a guest. I've picked up a lot of useful info, but now I need to share something...
Our house was built around 1915-1916. It has cavity walls with double brick outer leaf and single brick inner. There is a horizontal bitumen damp course, but the cavitys around the window openings are just closed with brickwork. Penetrating damp isn't an issue, but I'd like to do something about heat loss. It's a cold hungry old house and the only way gas prices are going to go is up.
I've done an exploratory on one of the window openings. It'll be comparatively easy to knock out the brick closers, make good and leave an open cavity. I was thinking of then closing the cavity with a thermal break closer from Screwfix, maybe bonding it in with expanding foam.
I really want to know if there is a beter product and or method to achieve this. Has anyone done it, or does anyone want to tell me my house will fall down?
