Fitting a radiator to a plasterboard wall with no studs?

johnju · 8 Apr 2009

Hi there my problem is that i need to fit a new radiator to a slightly non standard type of wall.

This is a prefabricated type wall which comprises of two sheets of plasterboard held together with what seems like a cardboard honeycomb. There are no studs anywhere across the wall just a wooden frame around the perimiter of the wall.

I would think my best option would be 12mm horizontal battons fixed on the other side of the wall and bolted through but this will look ugly in the next room!

Are there any fixings that could be used, ive toyed with the idea of using these..

any advice gratefully received before i flood the front room

Use these, http://www.screwfix.com/prods/11595/Fixings/Cavity-Fixings/Mungo-Metal-Easi-Driver-39mm-Pack-of-100

Also apply silicon to the brkt when fixing. Thats what I use on hollow walls and never had one move.

I would never use this sort of fixing to take any weight. I've seen plenty of radiators come off walls where these have been used.

If it's not possible to insert battens use http://www.screwfix.com/prods/18266...Hollow-Wall-Anchor-5-x-43mm-6-13mm-Pack-of-10

I always use extra fixings as well if I have to use these.

I use these.

Smaller hole required than the Rawlplug Spring Toggle Fixings, and you do not lose the end if you remove screw.

It is paramount partioning and will only be 9mm board but these worked for me. Make sure the length will not damage the board on other side.

All the fixings posted will work. However, the last ones are the strongest

I fit about 8 rads every day and have used both types, i would reccommend the last type

How about timber 'legs' behind the brackets that will support the weight of the radiator down to the skirting or floor and then the wall only takes horizontal load keeping it upright?

totally agree with david, been using same fittings ( different maker) for 3 years now but using the fixing tool to set them (about £6). 100% success with them.

I've never had any problems with these used with, as Craig says, silicone down the back of the bracket

I have had problems Gas4You. Sometimes they spin and the plaster crumbles.

Had a similar prob with kitchen cabinet recently, used same fixings, had a prob with fitting spinning and digging in on one used a screwdriver to hold the others still.

I would only use the screw in type for small rads anything longer than 1m I would use the interset type as stated by swbjackson, it helps if you have the right tool to fit them - one of these;

No, have never had a problem with these Jacko

, Do use the hollow wall anchors for towel rads though. As Mick says right tool for the job.

Should add I do fit four fixing per brkt and with the silicon the wall will move first
