We just had fiberglass batt insulation installed in the crawl space under our house. There is a strong odor coming from the crawl space that was not there this morning before the work was done.
I've never smelled anything like it and it is hard to describe. It's sickly sweet and also reminescent of something charred or slightly burned. It is what I might imagine burned cotton candy would smell like, maybe, but with other overtones as well. It's quite unpleasant.
I realize this isn't a lot to go on, but does anybody have an idea of what the odor might be, and if it is harmful? I would not have expected fiberglass insulation to have any odor at all.
I've emailed the contractor and asked for MSDS but probably won't get a response until tomorrow or Monday.
