Wall Insulation

Wall insulation refers to the process of adding material to the walls of a building to reduce heat transfer and increase energy efficiency. The insulation material is installed between the exterior wall and the interior wall, or in the wall cavity itself. This helps to keep heat inside during the winter and outside during the summer, reducing the amount of energy required to maintain a comfortable temperature within the building.

The process of wall insulation involves several steps. First, the walls must be evaluated to determine the type and amount of insulation required. The insulation material must then be selected and installed according to the specifications of the building and the desired level of energy efficiency.

The insulation material can be made from a variety of materials, including fiberglass, cellulose, foam, and mineral wool. These materials are available in batts, rolls, loose-fill, or spray foam form. The insulation material is placed between the exterior and interior walls, or in the wall cavity, to create a barrier against heat transfer.

Once the insulation material is installed, it must be covered with a vapor barrier to prevent moisture from entering the wall cavity. This helps to prevent mold and mildew growth, which can be harmful to both the building and its occupants.

Summary

In summary, wall insulation is the process of adding insulation material to the walls of a building to reduce heat transfer and increase energy efficiency. The insulation material is selected and installed based on the building’s specifications and desired energy efficiency level. A vapor barrier is also installed to prevent moisture from entering the wall cavity.
