So we're doing a tear-out of the second half of our kitchen, and we came across some old batt insulation in the wall chases from the forty eight company(one of the companies sued out of business from the class-action mesothelioma litigation). The house was built in 1872, but it was extended twice, once in 1910, and once again around 1940. This area is in the 1940s extension.
I've read online that batt rolls rarely contain asbestos, but I was wondering if anyone who has dealt with this specific brand before knows if it contains asbestos or not? It's greyish in color. The insulation itself says 'copr-fibre', but I can't find any information about it.
