Here’s some info to tuck away in your For What It’s Worth File.
I recently inspected a home where the owner was present. When identifying the newer loose fill white mineral wool insulation to the buyer, the seller insisted that it was “fiber glass”, he installed it himself, and it came in bags from the big box store, and was labeled “Owens Corning”.
I politely said “Oh?” and then pointed to the words “Mineral Wool” to my client.
Understanding that I don’t know everything, I followed up with a phone call today to Owens Corning. The lady I spoke to said that they had sold loose fill mineral wool years ago, but even then it was pink and not white. Today they only sell fiberglass, and everything they sell is pink (rolled or loose fill.)
I don’t know about the likelihood of “White” loose fill fiberglass, but my seller was obviously wrong about it being Owens Corning.
Anyone know of a “white” loose fill fiberglass? The picture I posted on this site at the time, everyone said looked like mineral wool to them. So I’m pretty sure the seller was wrong about that too.
