Air sealing and insulation are two distinct but complementary techniques used in building construction to improve energy efficiency and occupant comfort. Here’s a concise comparison of the two:

Air Sealing

• It focuses on preventing uncontrolled air leakage through gaps, cracks, and openings in a building’s envelope.
• Involves sealing areas such as windows, doors, electrical outlets, plumbing penetrations, and attic access points.
• Reduces drafts, eliminates cold or hot spots, and improves indoor air quality.
• Helps maintain a consistent temperature inside the building by minimizing heat transfer due to air infiltration.

Insulation

• Aims to minimize heat transfer between the interior and exterior of a building.
• Typically installed in walls, roofs, floors, and attics to create a thermal barrier.
• Reduces the amount of heat that escapes during winter and enters during summer.
• Common insulation materials include fiberglass, cellulose, spray foam, and rigid foam boards.
• Enhances energy efficiency by reducing the need for heating and cooling, leading to lower utility bills.

While air sealing and insulation contribute to energy efficiency, they address different aspects of heat transfer. Air sealing focuses on eliminating air leaks, which can account for significant heat loss or gain, while insulation provides a physical barrier that restricts the movement of heat. It’s important to integrate both techniques for optimal efficiency, as air leaks can compromise insulation performance if not addressed.
