Building Stud Walls Off Floor

[wcavanagh]

Interesting one here. We have removed all suspender timber floors, and concreted in an old 1900 cottage.

The plan with the floor is next a layer of kingspan, then wet UFH pipes, then a pumped self level screed.

At the moment it is all open plan, all walls have been removed, so my plan was I need to install the the Stud walls to define the rooms, prior to fitting UFH pipes, etc. Do I just screw the bottom CLS to the concrete, and build the stud wall up. Then lay insulation, and UFH pipework, and let them pump the screed in, this will cover the bottom CLS. Or do I build up the CLS to the 100mm depth so the screed just goes upto it?

Any advice would be great.

Lay your floor then do your walls, mark on the existing walls the position of the stud walls so you don't hit the ufh pipes.

Morning,

Thank you, seems very risky to me, I have many walls to build and not are all off an existing external wall.

You don't want to build walls off floating floors.

Lay courses of brickwork up to floor height, and then construct the studwork off that.

Now thats a good idea never thought of that.

Uhmm this is how it's done around here, a screed floor wound move, it's only a none load bearing internal wall.

You should have a ufh plan so you'll know where the edges of the pipes are, plus you always have a good bit of clearance around the perimeter.
You can always mark it on the ceiling.
Saves a good number of thermal bridges , less material and labour costs etc.

Do you live in Tombstone or some other wild west town? Ye Har

Load bearing wall or not, a stud wall will be loading the screed and insualtion, which is bad practice.

I have ordered bricks so will go with this plan, no issues with thermal bridge as I have put 100mm insulation under the concrete slab anyway.
