Flash and Fill Insulation Strategy

Materials/Tools Needed

  • Batt insulation
  • Spray polyurethane foam (large amounts required; use of a spray foam insulation contractor is recommended)
  • Blown-in or batt attic insulation
  • Pre-formed insulation baffles

Homeowner Tip

Consider replacing existing pot lights to IC/AT-rated LED pot lights to maximize the thermal effectiveness of the attic insulation.
