The Sag N Bag System is a double-layer insulation system that uses faced blanket insulation and unfaced insulation to provide superior thermal performance and energy efficiency.
Set-Up And Operation
First layer of faced insulation is installed perpendicular to and over the purlins, with the overall extra length to sag down evenly in between the purlins.
Top layer is installed parallel to and between the purlins on top of the “sagged” faced insulation.
