Vermiculite loft insulation

[Pickwickpick]

Not sure if this is right section of forum to post this, but I was up in customer's loft today and there was what looked like vermiculite (like sutff I use for gardening) up there as insulation. Was this a commonly done thing? Have never come across before now.

It definitely has been used. Seen it a couple of times and not for a while. Was some asbestos issue with it iirc...

Yes, my roofspace was originally done with it until replaced with fibreglass and I remember shovelling and brushing it up to put in bags to use for it for insulation mix around solid fuel built in boilers.
One point made to me about it is, - if you had a leak in roofspace, - the vermiculite would soak all the water up until it becomes very heavy and pull the ceilings down.

Can be handy stuff...insulating the void between liner and chimney for a solid fuel stove.

Just been doing a bit of googling after you mentioning this. Looks like I might have opened a whole can of worms here (as often seems to be the case!). Sounds like with pre 1990s, which this probably is, there could be either asbestos contamination from the mines, and/or added asbestos fibres for insulation purposes

Looks like I now need to do some research into how/where to get this tested!

Don't think it's a very high level asbestos hazard, I remember pushing it around to access bits and peices and, strangely - playing with it - if you get hold of a lump and squeeze it, it's got a really interesting wierd spongy texture, it's a bit like popping bubble wrap... I've never worried about it as a hazard tho. If you're going back up into that customers loft space - dyodd

Yeh I love vermiculite, fascinating stuff, use to use it to grow mushrooms back when I had a bit more spare time.

What's dyodd?

Check it out for yourself. Do your own due diligence.
