Can I use kingspan or the like, which has got wet due to storage outside?
Im either hoping to use it to insulate a concrete floor, or as insulation in a vaulted roof.
It will have been dried out by the time its installed.
Or is it going in the skip?!
Cheers

They say you shouldnt use wet kingspan, i guess they would say that. I would think used under a base any damp would dry out as the base does

you need to use 2 DPMs when using kingspan or celotex under concrete oversites
apparently concrete can rot it long term

there's no way I'd bin kingspan even if it's wet because it's too expensive.

Yeah, its what i have managed to accumulate of various jobs. I was hoping to use it in my own extension which im going to start next year.
Like you say, its expensive, so unless I hear otherwise, i will dry it out and use it.
LLL, im aware of the 2 dpm's, been doing that on various jobs for a while. Thats another expense, pricey stuff too!

JD i cant imagine it getting sopping wet like fibreglass
just maybe a bit damp
and as pablo says too expensive to chuck
i think the top dpm can be 500 gauge but we just use 1200 for both as its on site
