Air sealing the attic helps improve energy efficiency by preventing warm air from escaping in winter and cool air from escaping in summer. It also reduces the risk of moisture problems and enhances the overall performance of insulation, making your home more comfortable and cost-effective.
Air sealing techniques involve identifying and sealing gaps, cracks, and openings that allow air to leak in or out. Common techniques include:
- Weatherstripping: Applying strips around doors and windows to seal gaps.
- Caulking: Using a sealant to fill cracks and gaps in walls, windows, and other openings.
- Foam Sealant: Spraying expandable foam to fill larger gaps and penetrations.
- Attic Hatch Sealing: Ensuring the attic access hatch is properly sealed with weatherstripping.
- Ventilation Sealing: Sealing around vents and exhaust fans to prevent air infiltration.
- Electrical and Plumbing Penetrations: Sealing openings around wiring and plumbing where they enter the home.
Proper air sealing helps maintain a controlled indoor environment and improves energy efficiency.
