It can be difficult fixing to a wall that has been lined with insulation. Quite a
few people have asked me recently how to fix to a wall that has insulation
between the plasterboard and the actual wall itself. So this can be a real
problem because you can't get a good fixing through the actual insulation.
Then I came up with this idea to use a space plug.These are used extensively by
kitchen fitters etc and there is a guy in my forum Rob from Colour Republic who
uses these quite a lot on kitchen installations and also on bathroom
installations. I do have to thank him because I have watched quite a few posts
of him using these and that is probably what led me to the idea of using these
for this application. So the problem is if you put a screw through that
insulation you can't get a good fixing because it will start to damage the
plaster board and it will also pull the insulation in. This is just an
example block you would not normally get Jablite insulation in between the plaster
board and the block. It will normally be Celotex or something similar like that.
So I've rigged this up purely to demonstrate how to use the space plugs
in this application. So I'm going to put whatever I'm fixing onto the plasterboard
and we're just using this piece of water in this example and then going to
spot through the first hole. I'm now going to take a 38 millimeter hole saw which is
the exact correct size for the space plug and I'm just going to drill a hole
until I reach the masonry. I'm going to cut out the insulation and the plasterboard.
So you can see we have got a clean hole and we've also got a mark in the center
there where we need to drill for the wall plug. So I'm now going to take the drill bit put
that in the hole until it reaches the masonry and then I'm going to take
the plug and I'm going to take some insulation tape and pit that on there so
we know that we're drilling to the correct depth. I'm going to ensure that
that is centered into the pilot hole we've already drilled before drilling
the hole to the correct depth.
Now I'm going to clean out some of the dust obviously if you've got a vacuum
cleaner a vacuum cleaner will be ideal for cleaning that out.
I am now going to take the plug and I'll just push that in, I'm not actually
screwing that in so we can remove it, this is just to get the plug in the masonry
then we can insert the space plug.
It's actually sticking out a bit that so I will just wind it in a bit so it is flush with the surface.
That is now perfectly flush. We can now take the material that we're fixing
place the screw through it, put that straight through the center of the space plug
until it touches the plug in the material behind and then we can tighten that up.
So we can now level that up before spotting through the next fixing hole.
So that is a really good way of fixing to a wall that has insulation in between the
plaster board and the external blocks of the wall.
