A method of insulating your attic is Owens Corning loosefill insulation. Instead of laying batts or rolls, our AttiCat^® Insulation Blowing Machine conditions the AttiCat^® Expanding Blown-In PINK^® Fiberglas^™ Insulation by fluffing it along the length of the hose, adding millions of the tiny air pockets that give the material its insulating power. Because Fiberglas^™ insulation will not settle, it will maintain the same energy-saving level over time, keeping your home comfortable for years to come.
