Dealing With Furnace Problems

Overheated By High HVAC Bills? Wall Insulation Information Homeowners Need

12 March 2021 by Eliza Chapman

The recent blast of sub-zero weather caused many American families to suffer twice. The first instance of discomfort was, of course, caused by the need to stay warm during the extreme weather event. For many, however, the later massive heating bill was just as painful. 

Homeowners who are unhappy with their current heating bills may want to consider increasing the wall insulation in their homes. If you are unsure about whether your wall insulation should be improved, this information can help. 

Look beyond attic insulation

When homeowners decide to add insulation to their existing homes, they often focus on their attic. While it is true that heat rises and adequate insulation in the attic space is necessary to prevent upward heat loss, wall insulation is also important, especially in windy climates.

Since the area of the exterior walls is typically greater than the area of the roof in most homes, heat loss due to insufficient wall insulation can be a big problem. If the home is an older one, the existing wall insulation is likely to consist of a basic fiberglass batt that may not offer the same R-value as insulation products manufactured today. 

Wall insulation can also deteriorate as it ages, especially if the home has suffered water infiltration, rodent infestation, or other types of damage. When fiberglass insulation becomes compressed or is subjected to moisture, it loses the ability to insulate and provide comfort for the interior spaces of the home. 

Include the walls of the garage and enclosures

Interior comfort can also be improved by adding wall insulation to attached areas of the structure that were not insulated during the initial construction process. Unheated garages, porches that were enclosed after the house was built and mudrooms are some of the areas where adding insulation can be helpful in increasing comfort and heat efficiency in the main living areas of the home. 

Take advantage of modern insulation options

Finished wall surfaces can complicate the addition of wall insulation to an existing home. Homeowners who want to avoid removing exterior siding or interior drywall can choose less invasive insulation options, such as mineral fibers, polystyrene beads, and foaming products. 

Each of these insulation products can be installed by blowing them into place with an air-powered device or a special applicator. Mineral fiber and polystyrene insulation drift and settle into place inside the wall to seal places where air loss is occurring. Foaming insulation products perform a similar function, as they expand during the installation process. 

Your home's location, age, and type of construction will help determine your options for increasing the amount of wall insulation. To learn more, homeowners should reach out to a wall insulation service in their area.
