Summer is fast approaching and you’re probably starting to think about how you can keep your home cool and comfortable once the heat sets in. You might have air conditioning, mini split heat pumps, and ceiling fans on your list, but there’s another important element you need to consider, and that’s attic insulation. 

Attic insulation helps with cooling and is just as important in the summer as it is in the winter. Keep reading to learn more about how attic insulation helps in the summer and why you should make sure your whole home’s insulation is in good shape during the warmer months. 

How Does Attic Insulation Work?

Attic insulation works by slowing down the transfer of heat into and out of your home via your attic. 

In the winter, heat is constantly rising up into your attic, and trying to move outside where it’s colder. This is because heat naturally moves from warmer areas to colder ones. Attic insulation makes it harder for the heat to escape so your home stays warm when it’s cold outside. 

The same thing happens in the summer but in reverse—heat from the sun radiates down onto your roof and conducts into your attic as it tries to move toward the cooler temperature inside your home. Attic insulation prevents that heat from passing through your attic floor and into the living spaces below. 

Air Sealing Makes Your Attic Insulation More Effective 

Attic insulation makes a huge difference in home comfort and energy efficiency. But attic insulation can only stop conductive heat transfer; it cannot block heat that’s carried by air. In order for your attic insulation to work properly and protect your home against summer heat gain, you need to air seal it, too. 

Air sealing stops the free flow of air between your conditioned living spaces and your unconditioned attic. In the summer, it blocks hot air from flowing down into your home from your attic. 

To air seal an attic, spray foam is used to close up any openings that are letting air—and the heat it carries—pass through. Air sealing also stops air from traveling through your insulation, which can improve its performance and help it last longer.
