Thick plasterboard wall?

[rick]

Not stricly an electrical question so apologies if this is the wrong place to ask...

Has anyone ever come accross a dividing wall which appears to be solid/thick plasterboard? Drilling in for fixing trying to feel for the cavity and drill bit emerged in room next door. Wall seems to be plasterboard like substance around 2-2.5" thick.

I've not come accross anything like it before, interested to know if anyone else has.

Thanks

There a few 60s estates around here that have something similar, 2 plasterboard skins with a core of compressed straw. These are nightmare to chop out for boxes and also to get fixings in.

Think it was called "STRAMETT BOARD" or something similar, giving my age away again

I've come across the very thin "eggbox" walls before but never anything that thin.

My old house was like that, built in the late 80's 2 pieces of plasterboard stuck together that was it. No stud. You could hear everything through all the walls and could only have sockets on the party walls

My brother's house was built around 10 years ago and his party wall is double plasterboard. Not sure if this is standard practice, but I think the builder was on the take.

You can get a double plasterboard with corregated paper/card filler in the middle, not seen it for yrs but that may be a reflection on the fact I don't do installation work anymore.

re thread title. do not enter this wall for the chase. it's suitable only for the jeremy kyle show.

Gypson blocks ? found in older houses usually finished wall is around 2 to 3 inch thick. If you need a good fixing in this type drill the hole hoover out the dust spray in a little water put in a dab of expanding foam and push in wall plug and allow to set.

how do you put in a dab of foam without rendering the rest of the can useless, as the nozzle solidifies?

I'm sure it's called paramount partition wallboard. Or as has been said "eggbox wall. It was constructed with 2 sheets of half inch plasterboard held together with a grid type construction about one and a half inch squares and one inch deep. They used 0ne inch square timber to hold it together and a piece of one inch square timber top and bottom to make it sturdy. Before Dry lining boxes came out they used to get the position of switchboxes and knock a piece of noggin in from the edge during first fix. I think it is why dry lining boxes were designed.

allow the foam set in the straw and then poke it out with a wire do it often now try it.

Use a foam gun and gun grade foam much more usable than those one shot amateur foam cans

There's a very big estate of nearly 300 timber frame bungalows a few miles from me where all the internal walls are paramount boarding, the metal switch and socket boxes are held in by 4 inch nails through the sides of the boxes and wedged behind the plasterboard, I've replaced dozens of them with dry liners.
