Hi all. I am renovating a bathroom at mo and today while removing the tiles and boarding I have discovered what looks like corrugated wall sheets from cardboard. Anyone ever come across these before?

Cheers

Over the years as walls have moved I have changed it to studding and plasterboard.

Kitchen rad is 600 x 1800 double , its bolted through the straw with 4 x 75 mm x 8 mm bolts with 40mm washers . Its a good job it wasnt a customers when I found the straw . Its called stamic , or something like that , strangely it didnt take off lol

Never seen it before and couldn't believe it when found. This stuff is about 2 inches thick with dot and dab on either side. I need to move a doors location and put shower valve in this stuff but not deep enough for valve.

Can you run a vertical waste in it from a wall hung basin or is it best to knock down and stud the walls out.

Cheers all.

Personally I would take it out and rebuild it or at least cut the one side down and rebuild. It is fairly strong stuff though but so thin you will struggle to get a 22mm through it let alone a waste pipe.

Stramit board, the straw stuff, I am sure is made same as an Archery Target Boss.
The egg board stuff, I don't know what they were thinking. What's all this perform like in a fire?

Paramount partition board most likely.

"studs" are tiny and spaced massively apart.
The eggshell structure actually makes one side of the plasterboard support the other (hence the lack of traditional studs) .

So if you cut too large a hole in one side it affect the strength of the opposing side.

Crap stuff and alot thinner than normal walls.

It's alot of work but I personally remove and replace with traditional stud wall as has more strength for mounting, and space for sound insulation.

Yes it's Paramount walls. We come across it quite a bit round here. Horrible stuff for getting shower valves/pipes in.

As said above, if possible remove and replace with a proper stud.

I have seen them in Dunstable. They can turn a simple job into a nightmare if dropping cables or pipes down the stud wall cavity is your plan.

I had Paramount walls in my last place, the only advantage to them was getting cables down the wall got easier as I used drain rods, pushing them through the corigations down from above.
