Strawboard Wall fixing

[efiste2]

The bloke that I work with is a fully certified spark in his life outside of work, and he was describing a job he has looked at that has what he only described as strawboard interior walls. not being a spark myself I have never come across this type of wall, the closet I have seen to it (as he describes its) is what came of my flat roof when it was renewed, ie a compacted straw filler between two sheets of board.

Anyway he reckons there is some sort of special fixing stuff that allows you to fix backboxes etc etc to this "straw" type wall but he cannot recall what it was called and nor does his regular wholesaler. I thought he meant gripfill of NO-Nails but he thinks not.
Anyway I said id ask you more experienced chaps on here if you have ever heard of this "special" stuff that allows you to fix to this "strawboard"

It would probably be productive to talk to/look at the websites of makers of the boards, to see if they have info on how to install backboxes etc.

I don't think it's made any more. When I've come across it on refurbs the builders have said it was briefly popular in the (I think) '70s but didn't last long. And I doubt the manufacturers would have cared twopence about the likes of us getting cables and back boxes into their product anyway. I've seen straw used more recently as wall filler, but that's been on eco-friendly one-off builds and not using these straw-sandwich boards.

I remember that horse shyt used to stick to straw quite well, never tried it on backboxes though!

It's still pretty easy to find - for example click here . It's not 'loose straw',or anything like it - it's essentially a variation on the theme of chipboard or MDF, made from a different material.

a compacted straw filler between two sheets of board.

If it's the stuff I'm thinking off, the wall is about two or three inches thick, and it's plasterboard either side. If so, you should be able to cut a hole in the plasterboard, rake out some straw, and fit a dry line box to the plasterboard, which simply clips to the plasterboard.

I seem to remember once you cut into the board, the straw can start to expand, so you need to fit the box sooner rather than later.

Apologies if I am thinking of something different to what you have.

The strawboard I've seen is not such that you very easily be able to 'rake out some straw', any more than you would be able to 'rake out some woodchips' from chipboard. In fact, the stuff I've seen looks (and behaves) very much like chipboard (including the relatively hard facings). However, like you, I don't know whether what I've seen corresponds to what the OP is dealing with.

The stuff I thought it may be is a bit similar to egg box walls.

Ah. In that case, we're definitely talking about different things!
