I was hoping to find someone else that used owens cornings miraflex insulation in their attic. It was on the market in 1995 and was taken off the market ? I'm having a problem with my ceilings sagging in the early spring and in the early fall. The common factor is the warm days and cold nights. I was hoping that someone out there might know someone that is also having the same problem, that I am..... I'm in need of others who are also having this problem.
