When it comes to creating a comfortable and energy-efficient home, sealing it against air infiltration is a crucial step. A reliable insulation company understands the significance of this process and employs various techniques to ensure that your home remains cozy in winter, cool in summer, and energy-efficient year-round. In this article, we will explore the ways in which insulation professionals seal homes to combat air infiltration.

Comprehensive Home Energy Audits:

Before diving into the insulation process, reputable companies conduct thorough energy audits to identify areas of concern.

Utilizing advanced tools like thermal imaging cameras, professionals pinpoint sources of air leakage, such as gaps around doors, windows, and utility penetrations.

Weather Stripping and Caulking:

One of the primary methods used to seal a home is the application of weather stripping and caulking.

Weather stripping is applied around windows and doors to create a tight seal, preventing drafts and air leakage.

Caulking is used to seal gaps and cracks in walls, ceilings, and around fixtures, ensuring a continuous barrier against air infiltration.

Insulating Attic Spaces:

Attics are notorious for being a major source of heat loss in homes. Insulation companies pay special attention to insulating this space effectively.

Insulation materials, such as fiberglass or cellulose, are installed to create a thermal barrier, reducing the transfer of heat between the interior and exterior of the home.

Sealing Ductwork:

Leaky ductwork can significantly contribute to air infiltration. Insulation professionals inspect, repair, and seal ducts to ensure that conditioned air is efficiently delivered to every room.

Duct sealing involves using mastic or foil tape to cover any gaps or joints in the ductwork, preventing air leakage and improving the overall efficiency of the HVAC system.

Spray Foam Insulation:

Spray foam insulation is a versatile solution that expands to fill gaps and cracks, providing an airtight seal.

Insulation companies often use spray foam to insulate wall cavities and other hard-to-reach areas, creating a seamless barrier against air infiltration.

Insulating Crawl Spaces and Basements:

Crawl spaces and basements are common areas for air infiltration. Insulation professionals use various materials, such as foam board insulation or spray foam, to seal these spaces and prevent drafts.

Window Upgrades:

Upgrading windows to energy-efficient models is a significant step in sealing a home against air infiltration.

Double-pane or triple-pane windows with low-emissivity coatings and insulated frames can greatly reduce heat transfer and drafts.
