Your Attic and Energy Efficiency

IDT Energy , ,

Air leaks can often be traced to your attic- resulting in a house that’s too warm in the summer and too cold in the winter. The Residential Energy Services Network offers several tips for insulating your attic:

  • Seal holes or gaps around chimneys or furnace flues to prevent air leaks.
  • Use metal flashing for larger gaps and high temperature caulk for smaller ones.
  • Identify and seal all air leaks before adding additional insulation.
  • Seal small gaps around plumbing stacks and electrical wiring.
  • Use caulk for small gaps and spray foam for gaps up to 3 inches in diameter.
  • Use a combination of foam board and foam spray for gaps larger than 3 inches in diameter.
  • Use weatherizing materials or a pre-made attic cover to insulate your attic hatch or door.
  • Make sure attic soffit and gable vents aren’t blocked to ensure free airflow.
