Topping up Existing Insulation

Materials/Tools Needed

  • Spray foam (spray can or two-part) and/or polyurethane sealant
  • Batt insulation
  • Blown-in or batt attic insulation
  • Pre-formed insulation baffles

Homeowner Tip

The attic floor should not be used for storage unless a platform is constructed above the insulation. Any compressed insulation should be re-fluffed to the original depth if the attic floor is walked on.
