Flooring first or electrics / insulation?

Steve111222 · 24 Mar 2019

Hi,

I'm in the middle of renovating my property it's got three levels; ground floor, first floor and then loft conversion on the top.

I'm at the stage where the building is water tight and I've got all the partitions up on the three floors.

I am thinking to put the floors in next - Tounge and Groove in the Loft and then WBP Plyboard all on the second floor. The ground floor is concrete/screed.

Would it be an issue if I work from top down - so fix the Loft floor boards down first. Then from the first floor, run the wires for the first floor ceiling, then plasterboard the first floor ceiling and put the wool insulation between at the same times as the ceiling plaster boards? (and repeat for first floor).

Or do people tend to do the electrics and insulation from the top (i.e. run the cables for the First Floor ceiling, use something like chicken mesh and add insulation, then put the Loft Floor in).

I would leave all plastering until later.

Schedule your work, if possible so that 1st fix electrics can be done in 1 hit, same with plumbing.

I would suggest it would be worth discussing with your electrician and plumber before you get too far -they will be able to advise on routing to make yours and their life easier.

I always get our electrician to run cables around the perimeter of each orangery, usually just after floor insulation. Ive seen plenty of electricians run wires diagonally across the concrete slab -pain the backside when laying the insulation

yep sorry i mean 1) put the floors down 2) electric and plumb first fix 3) insulate and board from underneath.

At the moment in the loft and first floor, it is just bare joists and i've put a few plyboard sheets down so we can walk there; electrics and plumbing will be done in one hit, but is it worth me fixing the floor first?

it sounds like probably not until the electric first and plumbing first fix is done?

Floors should be down before stud walls are built. Ceilings should be left exposed for cables/pipes etc.

Definitely fix the floor first. You will need to poke pipes and cables through the floor at various points and it's easier to put a pipe through a hole than to try and drill a hole in a sheet of ply and then get it to fit over a pipe!

Ok thanks all - what about the floor insulation? Should i put the netting and insulation before laying the floor like in the attached picture?
pipes / wires etc will be after that.

You will find that rockwool will hold itself up if you cut it generously oversized and stuff it in. No need for chicken wire.
