My kids were hitting the ceiling today with a pool noodle and I am now scared that they have exposed themselves to asbestos. I also scraped the ceiling with the metal part of my measuring tape just now when I was trying to measure the tile. I am worried sick!The house was built in the late 60s but I don't know when the basement was finished or how old the tiles are. They appear to be 22 inches x 22 inches. Does anyone have any idea is these look like asbestos tiles? Also does anyone know what type of asbestos are in these types of tiles?
