Hi JIM.

thanks... there's lots of nasty stuff in concrete,
I didn't realise plasterboard could be hazardous (or is is just dusty)

glass fibre as in insulation? - they're making insulation with "bio
soluble glass fibre" now... dunno exactly what that means, but it doesn't
seem to create as much itch as the old stuff did, or maybe I'm just more
careful...
