How to Reduce Heat Transfer and Increase Comfort in Your Concrete Basement

Insulating your concrete basement walls is a vital home improvement in order to keep your home comfortable and energy-efficient. Basements built with concrete, stone, concrete block, and other masonry foundation materials have minimal insulating properties and cause approximately 20% of your home’s heat loss. In areas with cold climate, this are can become extremely uncomfortable if not properly insulated. Luckily, there are three ways to insulate your basement and maintain a comfortable environment throughout the year.

The most popular and convenient insulation method is an interior application. This involves installing insulation on the inside of your house, usually during remodeling or repairs. The most common types of insulation are fiberglass batt insulation, foam insulation, and blown-in insulation. Each type of insulation has its own R-Value, or thermal resistance, which should be considered when making a decision on the type of insulation to use. It is recommended to wear protective clothing, such as a long-sleeved shirt, long pants, light work gloves, respirator mask, and safety goggles when working with insulation.

Once the basement is dry and all defects and crack have been fixed, begin by stuffing the insulation in the gaps and crevices of the basement. After the cavities have been filled, use the staple gun to keep the insulation in place. Fiberglass batt insulation may be the easiest and cheapest insulation method, but take caution when handling the material. Each insulation type should be compared to determine which is most practical and applicable to your needs. All gaps and cracks should be filled, including all areas around windows and doors. Check all areas to confirm that no gaps exist where heat could escape.

Before beginning the project, it is important to check your local building codes and regulations to ensure the insulation will meet fire codes. Consulting a professional is advised if you’re uncertain about any interior features that may make the project more difficult. Once you have consulted all relevant professionals, purchasing, cutting, and installing the insulation should be simple enough for a novice.

Insulating your basement will not only keep your home comfortable and energy-efficient, it can also save you money on energy costs. With proper insulation, your basement can become a great place for relaxation, entertaining and storage. With a little research and the right materials, you can make your concrete basement walls insulated and ready for use.
