An old form of thermal insulation?
In our house, completed in 1941, it’s literally millions of tiny loose beads. Making a hell of a mess when opened up from below, for various works.
Thanks, not come across this before but a little googling would have you spot on.Definitely stramit board, compressed straw. Should not have any asbestos concerns because if fire resistance was required borax would’ve been used.
Not that Vermiculite stuff? Don't want to be alarmist but a lot of that was shipped from Montana and was contaminated with asbestos.
Ah, that's good to know.Genuinely thanks for this, I wasn’t aware. Yes, it would be Vermucilte. The power of the internet, checking online, little Vermiculite was imported to the UK from that Libby mine, Montana. You’re quite right, 100’s died in that one town alone from the asbestos, terrible stuff. Banned since 1990.
Vermiculite from any other mine/quarry is completely harmless.
Ah, that's good to know.
I just remembered when we moved down from Glasgow in the 60's, the roof of our house had a layer of the stuff and the old man wanting shot if it.
If you moved down from Glasgow just having a roof was cool wasn’t it ?
We lived in the posh bit
There’s a posh bit ?
Oh yes, it's the bit where you don't get stabbed straight away....as long as you're wearing the right scarf.
Seriously, it's a friendly city and great fun. If you've never been, give it a go.
