Is this plasterboard?

Post by Another » Fri Jan 25, 2019 5:01 pm

Hi all

Bit of a silly one. I never do DIY but I’ve put a large hole in one of the external walls of my flat.

Can anyone please confirm that this is simply double plasterboard and not something else like AIB? My block of flats looks to be built around the 70-80’s.

Looks to be a plaster skin, two plasterboard and then a timber frame with a yellowish insulation (image https://m.imgur.com/gallery/immXeMR ), then a reddish brick (which I’m thinking are engineering bricks as the other side is the stairwell.

Thanks!

Your image link does not work.
Fret not, a forum is a collection of opinions. Above, are mine.

Which is correct? Metre or Meter? Click the link to find out more.

Working on anything electrical? have you got a multi meter? why not? Would you hit a nail with a shoe?

Sorry not sure why the link didn’t work

To note. I used these to cut the hole https://www.screwfix.com/p/bosch-self-c ... -pcs/5393v which is why I think the papery stuff looks fibery. I’m a computer guy so have no idea with this stuff which is why it’s got me concerned

That's certainly double skin PB with a layer on insulation beyond. On materials installed pre-1999 (when a blanket ban on the use of asbestos and asbestos-containing materials in construction came in), without testing, you cannot ever be certain that there is no asbestos in the boards (and there were in the past insulated PB boards that contained asbestos - mainly used on local authority builds, I believe). The problem is that asbestos fibres are so small (finer than a human hair and very short) that they cannot be resolved by the human eye. It is highly likely that this is just ordinary PB, though

As Job and Knock says looks like double plasterboard, there are suggestions that plasterboard contained asbestos but I have never heard of any testing positive certainly in the UK.
HSE do not flag it up as a risk which I would expect if the rumours were true. I might be suspicious of fire doors that have a "plaster" core though. Double plasterboard was used as an alternative to asbestos for integral garage ceilings as it is pretty fire resistant in it's self.
