Best Dry Lining Box
 

Hi all

A colleague is batoning and insulating a cold wall, with 12mm plasterboard
to cover.

I have suggested that he makes sure batons are installed close to the
proposed double socket location and that he uses a dry lining box.

As this will be for a socket (which take more hammer than switches
obviously), can you guys recommend the most sturdy box please?
There seem to be various types on the market, some of which look well waffey
to me!

Thanks

Phil

It's not the boxes that give out but the plasterboard. Most seem to have
the same size sideflaps so little to choose there in terms of load
spreading. To my mind they'd be better if they had extra flaps top and
bottom on the double boxes as they're nearly always going to be socket
boxes.

Having said that, I fitted a double socket in an existing plasterboard
wall the other day using one and was surprised at how solid it felt.

If it was me, I'd simply set a 35mm metal back box into the existing
wall so that it'll sit flush with (or slightly behind) the front face of
the plasterboard when it's fitted.

Where are we going and why am I in this handbasket?

Thanks Scott

That was my first thought - I like metal boxes screwed to something solid!
But that would cause a cold bridge to the solid/cold/damp outside wall.

I screw wood battens (1 x 1/2" or so) to the back of the plasterboard and
fix a metal box to those. Handy in a partition wall. It sounds quite long
winded but doesn't actually add much time to the installation. Of course I
realise a pro sparks wouldn't have the time for this.

So do it but the times I've used a drylining box on plasterboard the
fix is firm enough but I've always tried to as close to a stud as
possible rather than in the middle of span. The noise as the whole
wall acts a sound board as you plug/unplug/switch is another matter.

But that would cause a cold bridge to the solid/cold/damp outside
wall.

I'm wondereding how the spark is going to deal with fixing boxes to
plasterboard with 50mm of kingspan bonded on the back and running
cables to them behind the 8x4 sheets...

This is a DIY job.
My colleague intends to fit batons to wall and infill with kingspan.
Then cover over with kingspan over top of batons.
Then plasterboard over.
The cables will come up through the floor behind plasterboard in channel cut
in top layer of kingspan.

;-) Put it this way - it makes the box to plasterboard fixing as strong as
the plasterboard. It also allows easy and perfect lining up of two or more
boxes close by. You do usually need to drill extra holes in the boxes,
though. To pick up near the middle of the batten.
