Is there any danger of bad fumes/gasses being released from polyisocyanurate or polystyrene rigid foam insulation? I'm planning on insulating my bedroom from the inside (ie: putting the insulation between the studs), and I'm wondering if I need to worry about fumes over the years.
My guess is there's no issue, as people use this stuff all the time, and my vapour barrier will prevent any air movement anyway. Still, it was brought up by a hardware store I called, so I'd like some sanity-checking opinions.
Edit: Since I've been able to find precious little information on insulating the inside of exterior walls with rigid insulation, I've decided to go with Roxul (fibreglass-ish) insulation instead.
To answer my question though, I've asked people IRL, and they pretty much scoffed at the idea that rigid foam insulation gives off fumes.
