Air Sealing


Air sealing is a crucial aspect of insulation that involves sealing gaps and cracks in a building’s envelope to prevent air leakage. It ensures energy efficiency, indoor comfort, and structural integrity by minimizing heat loss and air infiltration.


Air sealing refers to the process of identifying and sealing air leaks in a building’s envelope, including walls, windows, doors, and penetrations. It involves using various materials such as caulks, weatherstripping, and sealants to create an airtight barrier.

Key Features or Components:

  • Identification of air leakage points
  • Selection of appropriate sealing materials
  • Proper application techniques
  • Assessment of air sealing effectiveness through blower door tests

Importance in Cleaning Service:

Effective air sealing is essential for maximizing the performance of insulation systems. It helps maintain consistent indoor temperatures, improves indoor air quality, reduces energy consumption, and lowers utility costs.

Inspection Criteria:

During inspections, professionals evaluate the completeness and effectiveness of air sealing measures. They look for signs of air leakage, such as drafts, moisture infiltration, and temperature variations, and assess the integrity of sealing materials.

Common Issues and Failures:

Common issues include improper installation, inadequate sealing, deterioration of sealing materials over time, and failure to address hidden air leakage points. These issues can compromise energy efficiency and indoor comfort.

Maintenance and Repairs:

Regular maintenance involves inspecting air sealing components for damage or deterioration and addressing any issues promptly. Repairs may include reapplication of sealants, replacement of weatherstripping, and reinforcing sealing around windows and doors.

Regulations and Standards:

Building codes and energy efficiency standards often include requirements for air sealing in new construction and renovation projects. Compliance with these regulations ensures that buildings meet performance and efficiency goals.
