SANCTUARY Blow-In or Spray-Applied Insulation


As the first all-in-one fiber insulation, SANCTUARY by Greenfiber can be loose-filled, dense-packed or spray-applied into attics, walls, floors and ceilings to significantly improve comfort, safety and well-being. SANCTUARY is engineered to fill every gap and hard-to-reach place without time-consuming cutting and fitting, reducing air infiltration and creating a tight thermal envelope for fewer callbacks. Capable of reducing sound power by 60% and heating and cooling costs by up to 20%, it's made from recycled plant fibers which keep carbon locked in for the life of your home, lowering homeowner’s carbon footprint and reducing global warming.
