Wires and insulation

[con1_uk]

On the floor it is then cheers.

What about my insulation then? Will it be ok to run it to within 3 to 4 inch away and cut around the sockets?

Thanks.

Forgot to ask, will the wires when run on the floor just be loose or should they be fixed to the wall?

Twin and earth is supposed to be fixed, otherwise you might as well use flex. However, it could be argued, in your case, that it is best to leave it unfixed, just in case a long drill bit comes through from below or across the wall. With it being unfixed, it will simply move out of the way as the drill bit touches it. Of course, this is not a situation you should expect. Remember what I said about common sense.

Your plans for the insulation are OK.

Thanks a lot for you answers (And patience)

Last question (I think) whats the best way to fix the rockwool between the studs so it dont fall down?

Thanks.

Use duct tape, stapled/tacked to the back of the studs, to keep it position.

 

[con1_uk]

Probably for the Building forum but is it ok to fix it to the back wall?

Hello again had another thought.

Instead of going with the rock wool solution could I use the stiff board insulation to wedge between the studs can this stuff go near to the cables or does it have the same rules as the rock wool?

With this stuff it will be wedged between with no chance of falling onto the cables and making them too hot so if the cables are run along the floor then the nearest insulation will be on top of the 3 by 2 stud work. Is this a better solution?

Thanks.

Go into any new house and you will find that all the loft lighting circuits are run under the insulation and even shower cables the same.

Pull up your landing and you will find cables lying next to your central heating pipes.

So in reality - it really doesn't matter what you do as no-one else out there seems to care less.

However...

Cables, especially shower or immersion cables should not be buried in insulation. Lighting cables are usually so lightly loaded that it does not matter.

Cables should not be put next to hot pipes as it shortens the life of the PVC insulation.

Go down any high street and you will see cars speeding over zebra crossings and past schools; but that doesn't make it acceptable.

Con,
Its all about ventilation to prevent the cables from overheating. Insulation material of any kind, obviously, does not permit good ventilation. So, if the insulation board is jammed between the studs it should not interfere with air movement just above the floor behind the stud wall.

Do you really think thats the advice you should be giving

It's not advice. It's the way things are done in the real world. Have you ever seen a new house wired in any other way?

Professional electricians and competant tradesmen/diyers on here are only going to tell people the correct way to do something.Which category do you fall into joe-90?

The category that sees the entire electrical trade wiring up houses knowing full well that the cables will be covered by insulation. If it's wrong - why are you doing it?

I don't and I wouldn't

It's beyond our control what people do after the work is finished... When they are clipped to the top of a joist we are doing as much as reasonably possible to reduce the chance of them being covered in insulation - out of curiosity where do you suggest we put the cables?
