We are modernising that part of the house and would like to sort this out. We will be removing the big sash window and replacing with two smaller windows (one each side like in a normal house). I guess I could extend the block wall (with stone rather than concrete block) so that it reaches the outer surface of the house and then windows in either side. Then fire can't get round and it would be like a 'normal house'. I don't mind doing that but wondered if there are any other solutions that would still provide adequate firestopping between the two houses maybe just with timber or metal windows side-by-side.

Many thanks for any help.

Whilst you are thinking about fire stops, what about the attic do you have a regulation firewall between the 2 houses up there?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16811&Focus=284857#Comment_284857 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16811&Focus=284857#Comment_284857 Mon, 23 Nov 2020 13:41:45 +0000 JulesB
Will do the last little bit in block and then it'll need a new stone mullion on the end of the wall which will split the current sash window in two and create a proper masonry division between the two houses.

Will be tackling the attic after this. Probably got the same problem but much trickier to access the outside of the window.

Incredibly heavy for the size but seem effective.]]>
