Hi Folks,

What sort of wall is behind the insulation??

If its brick/block i would use some brick screws http://www.shaftesburyfixings.co.uk/Concrete-Masonry-Screws.html You could also look at using a few frame fixers into the masonary.

If its a stud wall you'll need to find the studs and fix the brackets to these with long screws. There is quite a bit of weight in radiators so use a few fixings on each bracket.

Drill a 8mm hole use brown rawlplugs and use 5*100mm screws

The trick is not to pull the bracket through the plasterboard when tightening up the screw so a long washer is needed to give the bracket a solid surface to fix against
Usually a half inch copper pipe is cut to the distance between the surface of the plasterboard and the solid wall at the fixing holes Then a 110mm concrete screw is used to pull the whole lot together. Alternatively an express nail is driven in flush with the surface of the plaster board at the fixing points and a brown wall plug stick is driven in to the hole then screw home the bracket.

had the same problem as yourself,

got some of these from the builders providers

think they were 8mm x 90mm or 100mm

Bond the brackets with tech 7, fixings are becoming a thing of the past.

Stick them to the plaster/cardboard :eek:

I'm all for using Tek7, but the weight of the Rad + water would be very big. The last rad I fitted was 1M long double and weighted about 20Kg empty.

Let's hope the skim is well stuck to the slab
Tec 7 is great stuff in fairness but it's feck all use when your rads on the floor with a heap of paint and skim coat stuck to the brackets.
Put some make or shape of fixing in it.

Ye have no faith lads in the stuff, I know plumbers that bond wall mounted sinks and toilets with it, lots of carpenters bond in door frames, skirting and architrave with it. I was talking to a kitchen fitter a few weeks ago and he was fitting a kitchen in an old stone house and he couldn't get grounds so used tech 7 solid as a rock.

Tec7 is great tac and has got me out of many a hobble over the years but it's ony as good as the surface it's adhered to
Great for skirtings and the like but anything that's wall mounted fix it I'd sleep better at night knowing the next phone call from a client I get
Isn't going to be a telling off or an insurance issue

There's too many what ifs. What if the skim doesn't cling? What if you cling a toilets to a piece of a slab in the wall and someone sits on it and pull it off? That's madness. I'm all for skirtings but I'd scatter a few nails in it to hold it while the tec7 goes off. As for door frames again I wouldn't accept someone doing that in my house, some clowns put in door frames with expanding foam too that drives me mad!!

Did you ever see a door frame fall out that was secured with foam?

Fall out on the floor no because the architrave won't allow it, come loose and move everytime you pull the door yes I have.

You, my dear man, are a delusional nutcase, plain & simple.

No, but you're advocating it as a viable option and potentially putting this suggestion as a solution for many novice DIYers around these parts. It certainly is not.

8mm or 10mm express nails 100 or 120mm long into de block. Use the length of wall plug that you can cut and cut some off and hammer into end of express nail. Rad will never budge
