How Can Insulation Help Save Energy In The Summer?

Summer is a time of the year that most people in Maine look forward to. The warm weather means picnics, swimming, barbecues, and days spent lounging in the sun! 

But it also means higher electricity bills, especially if your house is poorly insulated or sealed. The good news is that properly sealing and insulating your home can save money during the summer while staying cool and comfortable inside. 

This post will explore how sealing and insulation can save you money in the summer and make your home more energy-efficient.

Insulation Reduces Heat Transfer

Insulation can be a game-changer in keeping cool during the summer months — it reduces heat transfer from the outside to the inside of your house. 

When properly insulated, your home provides a barrier that keeps the cool air inside and the hot air outside. This means that your air conditioner doesn’t have to work as hard to maintain a comfortable temperature, which can translate into significant energy savings.

Seal Your House

Sealing your house is another way to save energy in the summer. Air leaks around your home’s doors, windows, and other openings can let warm air in for a while, allowing your cooled air out. By properly sealing your home, you can prevent this from happening. 

Not only will this keep your home cooler, but it will also lower your energy bills. Sealing your home may involve filling gaps or cracks in your walls, ceilings, or attic. 

At Seal It, we offer blower door testing. This simple test tells you how many air leaks are in your home — and the more air leaks, the less cool air stays in your home (making it far less energy efficient). 

Attic Insulation

One area of your home where insulation can be particularly beneficial is the attic. Most attics in Maine lack insulation, meaning they become stifling hot in the summertime — making the top floor of your home feel unbearable. 

Insulating your attic can create a barrier preventing heat from coming through your roof and into your living space. It can also prevent warm air from getting trapped inside your attic and resting heavily on the ceiling, making lower levels warmer. Keeping your attic cool with insulation can help to control temperatures throughout your house.


To sum up, sealing and insulating your home are some of the most effective ways to save money on summer energy bills. Proper insulation and sealing reduce the transfer of heat and prevent air leaks, meaning your air conditioning will not have to work as hard to cool your home. You can also save by insulating your attic, which will reduce heat escaping from your home in the winter or the warm air being trapped in the summer. 

By taking these steps, you can make your home more energy-efficient, increase your comfort during the summer, and save money on your energy bills. Call us at Seat-it for consultation on how we can help improve your insulation and help you save on your energy bill this summer.
