Many homeowners don’t realize the same insulation that keeps a house warm in the winter also helps to keep it cool in the summer.

Have you ever wondered why some people have such cozy homes no matter what time of year it is?

It’s not so much a mystery, as it is superior insulation. To create a house that doesn’t feel like a sauna during the summer with an air conditioner that’s constantly running, homeowners need an insulation that creates an air barrier – like foam insulation.

“Many homeowners don’t realize the same insulation that keeps a house warm in the winter, also helps to keep it cool in the summer,” said Eric Garcia, RetroFoam of Michigan general manager.

Keeping a home cool in the summer is done by using a window air conditioner unit or a central air unit. These are the only machines in the home that create cold air, as everything else radiates heat. Insulation plays a big role in maintaining a constant comfortable temperature.

Foam insulation creates an air barrier that keeps your cool air inside, while keeping the hot summer air outside. If the home doesn’t have an adequate insulation, then there is no barrier to keep the heat outside.

“Think of foam insulation like one of those foam cups you get at the gas station,” said Garcia. “The same cup keeps your coffee warm and your soda cold.”

When injection foam insulation and spray foam insulation are installed, the materials completely fill the cavities, including any gaps and crevices. This stops any air leakage and movement.

Another added bonus of creating an air barrier in a home is that the AC unit won’t run constantly in an effort to maintain a comfortable temperature. This doesn’t just make the home cool during the summer, as it will also save the homeowner money each month on energy bills.

Traditional insulation materials, like fiberglass and cellulose, don’t protect a home from airflow and leakage like foam insulation does. These materials are a poor choice for insulation if a homeowner wants to keep their home comfortable and more energy efficient.

When it comes to reducing air leakage, foam insulation is the best option as it provides both heat resistance and an air seal.

Since 2002, RetroFoam of Michigan has been insulating thousands of homes across Michigan’s lower peninsula with foam insulation. The company has been recognized the past several years by Consumers Energy for its work to help homeowners reduce their carbon footprint by making their homes more energy efficient.
