a) slightly chase the pipes into the exterior wall by removing some of the cladding

b) lay the pipes directly onto the clad exterior wall

c) do something cunning I haven't thought of

thanks for any help]]> waste pipes inside EWI https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17984&Focus=303716#Comment_303716 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17984&Focus=303716#Comment_303716 Wed, 04 Oct 2023 13:19:47 +0100 djh
It doesn't sound like taking off concrete render will make much difference from a space point of view and it might affect damp penetration until the EWI is in place so I'd be inclined to leave it in place. You could always add EWI around the pipes now rather than in a couple of year's time.]]> waste pipes inside EWI https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17984&Focus=303733#Comment_303733 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17984&Focus=303733#Comment_303733 Thu, 05 Oct 2023 09:15:17 +0100 maxsm waste pipes inside EWI https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17984&Focus=303740#Comment_303740 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17984&Focus=303740#Comment_303740 Thu, 05 Oct 2023 09:42:54 +0100 WillInAberdeen
How about putting the pipe on longer mounts so there is say 250mm gap between the wall and the pipe to run EWI and render through later. It might look a bit strange until the EWI is fitted - you could run a temporary strip of EWI up the wall now to fill it out.]]> waste pipes inside EWI https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17984&Focus=303755#Comment_303755 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17984&Focus=303755#Comment_303755 Thu, 05 Oct 2023 12:18:22 +0100 maxsm
