Our foreman has just suggested that if we're going to tile inside we might be better off with an insulated (and moisture resistant) tile backer board rather than insulated plasterboard. At least in the shower and maybe everywhere. Sounds reasonable I think.

I've looked at products available and nothing jumps out at me as "best bet". Anyone here got any recommendations?

If you are tiling fully, why not just use XPS? The tiles have been clinging happily to my XPS for around 30+ years. Oh, and please don't dot and dab! Full perimeter beads and cross-hatchings at least, but full coverage even better.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16208&Focus=275069#Comment_275069 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16208&Focus=275069#Comment_275069 Thu, 15 Aug 2019 15:01:48 +0100 owlman

P.S. Don't tile onto plasterboard, especially stone tiles.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16208&Focus=275077#Comment_275077 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16208&Focus=275077#Comment_275077 Thu, 15 Aug 2019 23:43:49 +0100 Jeff B https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16208&Focus=275079#Comment_275079 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16208&Focus=275079#Comment_275079 Fri, 16 Aug 2019 00:37:08 +0100 CWatters
Wedi board is a foam board with a cement/Fibreglass skin both sides designed for tiling. I used it to make a wash stand covered with travertine. Only issue is that if you ever want to take tiles off i think some of the foam may come off with them?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16208&Focus=275139#Comment_275139 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16208&Focus=275139#Comment_275139 Mon, 19 Aug 2019 10:55:21 +0100 Kenny_M
I used marmox multiboard the last time before tiles went on in a shower, easy to fix with the plastic washers they supply, but I am sure it can probably just be stuck on depending on the substrate. Found it easy to use and no issues so far.

Then I think I will leave the insulated plasterboard on place over the whole room and then put the conventional tile backer over that just where we need to tile. The insulated plasterboard is big sheets so it's quick and easy (though I'll look at full cover with notch trowel - the blockwork should be flat enough) and hardly worth omitting areas.
We have used Marmox multiboard before and I had wondered about using it for the whole room but the smaller sheets are way less convenient. Most of the room will just be a skimmed plaster finish.]]>
