Tiling on a cardboard wall!?

[LEH]

Pleased to see this come up again as I have the same walls and have been debating what to do. I read somewhere in previous discussions on the forum that you could overboard with marmox boards using adhesive and plasterboard fixings. I think marmox do long boards too so you would at least have fixings into the timber batten at the top and bottom of each board? What kind of weight you would put on this of course I'm not sure, probably only ceramic?

My worry with ripping off the whole side is that you're weakening the wall significantly during the process - how do you make sure you don't damage the remaining wall?

I'm a DIYer so not speaking from any position of experience, but I would be interested to hear your thoughts so I can decide between the two options!

Only you will know this as you will be working on it. Obviously if you have things bolted to the other side you will gave issues. If not then with care and a gentle hand it will come away just fine.

Sorry to pull this thread up again, but did you do any reinforcement of the joist(s) below the wall? As I understand it, stud partitions should normally have doubled-up joists under them, but because these Paramount walls are lightweight, there was often only a single joist under them? Presumably once you re-stud them they're quite a bit heavier thanks to the timber...?

I think that would only apply if they are structural stud walls . In building my house within the last five years we were not advised by the structural engineer or building control to do this .

"With timber or metal frame walls it is normally acceptable to support them on the existing floor joists (not the floor boards), either by providing a double floor joist underneath, if they run parallel, or across the existing joists if the floor joists run at 90° to the wall."

"Floor joists must also be doubled up and bolted together under timber partition walls, and in bathrooms due to the weight of a filled bath additional joists must be provided under the bath"

Are what got me worried.
