Air Sealing

Seal the Leaks. Save Energy. Improve Comfort.

Air leaks are one of the biggest causes of energy loss in homes—often more impactful than insulation alone. At Atlantic Insulation, Inc., our professional air sealing services close the hidden gaps and cracks that allow conditioned air to escape and outdoor air to sneak in.

The result is a more comfortable home, lower energy bills, and improved indoor air quality year-round.

Why Air Sealing Is So Important

Even well-insulated homes can suffer from poor performance if air leaks are left untreated. Small openings around framing, wiring, plumbing, and attic access points can add up to significant energy loss.

Proper air sealing helps to:

• Reduce heating and cooling costs by minimizing wasted energy
• Eliminate drafts and hot or cold spots
• Improve comfort in every season
• Reduce moisture intrusion and help prevent mold and rot
• Improve indoor air quality by limiting outdoor pollutants
• Increase the effectiveness of insulation systems

Air sealing is especially important in attics, crawlspaces, rim joists, and older homes.
