stud wall + building regs

[jeepster]

hi, extension shell buildt, on the first floor we will be constructing a stud wall to seperate 2 rooms. we have put triple joist down to take the weight of the wall, we were going to put the first floor chipboard floor down after putting up the ceiling in the room below.(making it easier to fit the soundproofing)

joiner says we cant do that as we have to contstruct the wall on to the floor, so have to put the floor down, then build the wall on the floor.

does anyone know if that is correct.

It makes no difference if the partition is built off the joists or the floor deck.

In practical terms, it is easier to lay the floor deck before the ceiling though

It'll be a lot more hassle to replace the boards should they ever need replacing if they get wet though.

Put the sole plate down before anything else goes in, then you can butt the floor up to that, then proceed with the rest of the wall.

If the wall is being built as a frame that's then hoiked into place, then just build it on top of the length you put down initially. Will cost you more in materials though, a few metres of 4x2

The only problem that may arise is if the width of the wall is the same as the three studs, therefore leaving the flooring hanging in the air where it meets the wall. Therefore just add infill sections up against the sides of the triple studs to support the edge of the floor. You needn't even use full length section for this, offcuts will do as long as they are flush with the joist tops and evenly spaced.

It's no big drama, about 1 hours work max.
