Exterior Walls Insulation is the process of insulating the walls of a building from the outside. This type of insulation can be done using a variety of materials, including fiberglass, cellulose, and spray foam. The insulation is installed by drilling small holes into the exterior of the building and blowing the insulation into the wall cavity.
There are several reasons why exterior walls insulation is important. Firstly, it can help to reduce energy costs by improving the building's thermal efficiency. This is particularly important in colder climates where the heating costs can be high. Additionally, exterior walls insulation can also help to improve indoor comfort levels by reducing drafts and cold spots. This type of insulation is typically installed during new construction, but it can also be added to an existing building as a retrofit measure. Overall, exterior walls insulation can provide many benefits, including improved energy efficiency, increased comfort, and reduced environmental impact.
