Is Plywood ok for a partition wall?

[Ronski]

I've got an en-suite that we are building, it will quite likely be tiled with Limestone, although we have not made a final decision.

At the moment the room is a bare shell, 2 walls are stud partition walls, my question is what would be the best covering for these walls in relation to tiling onto it?

Wall 1. 3.1m long x 2.3m high

The studs are 90 x 38mm, at about 400mm centres, the other side of the wall has 12mm ply with 12.5mm plasterboard, so the walls pretty sturdy.

Wall 2. 1.45m long x 2.3m high

The studs are 38 x 63mm, at about 400mm centres, the other side is 12.5mm plaster board. This wall will have a shower cubicle on.

I had intended on using 12mm or perhaps 19mm plywood.

What's your recommendations please?

I will be doing all the work/tiling myself.

I don't like ply on walls, plasterboard would be my choice or there is 12.5mm hardie backer which will take 40kg of weight m2

I would use a backer board of some description...not plywood....

1: it is not thermaley stable.
2: It will not support the weight of stone tiles.

Hardi backer 500 from most out lets or Knauf aqua panel from tile giant are great to work with..

wickes also sell the knauf aqua panels..

as above unless your tiles and addy weigh 32kg or less per m2,
then like whitebeam, i would use 12.5mm plasterboard.

Plasterboard, tanked in wet areas I presume guys.

Thanks for all your replies. I'll use a backer board, now just to find who can supply it at the best price - I have accounts with Jewsons and Builders Center, so shall give them a ring.

I've also got one wall which is Thermalite block, I presume it would be better to batten and board this wall, or can I tile straight onto it?

The fourth wall is some sort of block - it's very rough, looks like loads of little balls all stuck together, which I presume would be ok to tile straight onto.

i would dot and dab a 12mm plasterboard onto the thermalite blocks a lot quicker than batten and boarding as to the fourth wall im not too sure mate. hope this helps

Thanks for your reply

I neglected to mention that will be the wall with the bath on it, so with that in mind wouldn't Aquapanel be better?

And also if using Limestone tiles, would plasterboard take the weight?

if you are unsure about the weight being placed upon the plaster board i would recommend that you use hardi on all walls including the bath wall so as to make sure that the weight is not an issue.

depends on what limestone?

i belive applestone is the most heavy, and of course anything 20mm thick is out of the question.

you will need to pick your tiles first, weigh them, and then decide what to clad the walls with!
obviously, the safest bet is wedi,marmox etc. but this can cost a fortune and is not needed if the tiles ar less than 32kg inc adhesive.

platsterboard = £8.98 for 2400x1200.
wedi = £32.99 = 2500x600.

I am fitting 45 mtrs of applestone next week...and i weighed it....23.5kg a mtr plus 3.5kg for adhesive and grout...

Now moleanous limestone is heavy stuff for walls...:20:

my point proven dave, hes gotta get the tiles first!
i hate seeing good money go to waste!

 

[DHTiling]

But personally, whilst the room is stripped out i would backer board it out, then no probs..

The room i am doing next week the customer had the same oppurtunity, BUT plastered the walls instead.....now i am fixing nearly 50 backerboards..stuck and mechanicaly fixed as well.....reminds me..need a new drill..:smilewinkgrin:
