Sag N Bag System

Sag N Bag System

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.

Considerations

  • Insulation: between/over purlins, no banding
  • Appearance: purlins exposed
  • Building type: steeper pitches ok
  • Application: new
  • Meets older codes (IECC 2009, ASHRAE 2010)
