7 Critical Areas To Insulate In Your Home


Do you worry about the energy, money, and resources you use to heat and cool your home? Most people do, forcing them to look for ways to make their homes more energy-efficient.

7 Critical Areas To Insulate In Your Home

Other than investing in energy-efficient appliances, adequate insulation is an excellent option. The insulation can decrease your energy costs by more than 20%. Here are seven critical areas to insulate in your home.

The Roof

An old, leaky roof can let heat escape in winter and enter your home in the summer. It forces your furnace and air conditioner to work harder, costing you more money in the long run. A well-insulated roof will keep your home comfortable and your energy bills low. You’ll also prevent roof damage from ice dams and leaks. Start with a professional inspection from experts such as Kanga Roof to find and fix any leaks. Take care of any missing shingles, and consider upgrading your roof’s insulation. As you do this, don’t forget the attic. Without adequate insulation, the attic can be one of the most significant sources of heat loss in your home.


A poorly insulated wall can let out as much as 35% of your home’s heating and cooling energy. Take the time to insulate your walls properly, and you’ll see a significant decrease in your energy costs. Check for any cracks or gaps and seal them with caulk or insulation. Note that the insulation in your walls can settle over the years. Check it regularly and add more if necessary. If you live in a colder climate, go for a higher R-value and choose a lower R-value for warmer areas.

Windows and Doors

Old, drafty windows are one of the most significant sources of heat loss in a home, accounting for up to 30% of energy loss. To prevent this, make sure your windows are properly sealed and insulated. If you have single-pane windows, consider replacing them with newer, more energy-efficient models. Another option is covering the windows with plastic film. Gaps and cracks around doors let in drafts, making your home uncomfortable and costing you money. Caulk and seal any cracks or crevices and add insulation to the door itself. You can also hang a door curtain to keep the heat in. Replacing your old doors with newer, more energy-efficient models is another option.

The Basement

The basement is often the forgotten area of the home when it comes to insulation. However, it’s one of the most important areas to insulate. The basement is where a lot of the home’s heating and cooling energy is lost. Properly insulate the basement walls and floors, and install a vapor barrier to prevent moisture damage. Remember to protect the pipes and ductwork to avoid heat loss too.

The Floors

To properly insulate your floors, start by sealing cracks or gaps. You can then add insulation to the floorboards or install a floor insulation mat. Doing this will keep the heat in during winter and out during summer. Don’t forget to insulate floor pipes as well.

Outlets and Light Switches

Gaps around outlets and light switches are another common source of heat loss. To prevent this, seal the gaps with caulk or insulation. Also, add an outlet and switch insulation covers to keep the heat in.

The Ceiling

Warm air rises and collects at the ceiling when you heat the house. Install insulation between the ceiling joists to prevent this warm air from escaping. You can also add a vapor barrier to prevent moisture damage. Without adequate insulation, you’ll also realize the higher points of your home are warmer in summer.

Insulating Your Home Significantly Decreases Energy Costs

As you can see, there are many critical areas in your home that need adequate insulation. By taking the time to insulate these areas, you’ll see a significant decrease in your energy costs. You’ll also be more comfortable and better protect the property from moisture damage. Adequate insulation also prevents pest infestations, keeping your home safer.
