How to insulate your attic

Materials checklist

  • Silicone, acrylic latex caulk and/or low expanding foam for air sealing
  • High-temperature (heat-resistant) caulk for sealing around flues and chimneys
  • Foam board insulation to cover soffits, open walls, and larger holes. Alternatively, you can use drywall or pieces of plywood
  • Roll of 14-inch aluminum flashing to keep insulation away from the flue pipe
  • Weather-stripping for attic hatch

Important Considerations

  • The attic must be accessible and easy to move around in
  • Use proper safety equipment (dust masks, gloves, long sleeves, safety glasses, lights)
  • Attics can get dangerously hot on sunny days, especially in the summer. Make sure there is a friend or family member that can help if needed
  • Call a professional if you see any of these:
    • Damp conditions indicating a moisture or ventilation problem
    • Old (knob and tube) or faulty electrical wiring
    • Vermiculite insulation—usually appears as gray, silvery chips
