Does Attic Insulation Help In Summer?

Attic insulation is well known for its ability to keep our homes warm during the winter, but did you know that insulation can keep your house cool during the summer, too? 

Installing new attic insulation will make it easier for your home to block out the summer heat, leading to better comfort and lower energy bills. Keep reading to learn more about how insulation works and how it helps in the summer. 

Heat Always Moves Towards the Cold 

Heat will move from warmer areas to colder ones, and the greater the difference in temperature, the faster it will move. 

When you run your air conditioner during the summer, the temperature inside your home drops significantly below the temperature outside. As a result, heat from outside your home will try to make its way in. The hotter it gets outside, the faster this will happen. 

Insulation Keeps the Summer Heat Out 

It’s virtually impossible to keep your home cool in the summer when you have a constant onslaught of heat coming in. That’s why you need good insulation. 

Insulation creates a barrier that slows down heat movement. During the winter, it holds heat inside your home, and during the summer, it blocks it out. 

While it’s important to insulate many areas in your home, including your walls and your basement or crawl space, attic insulation is especially important during the summer. This is because the sun is beating down on your roof all day long during the summer, heating it up. That heat conducts directly into your attic and down into the cooler living spaces below. New attic insulation will help in the summer by slowing down this process, keeping your entire house cooler and improving its energy efficiency. 

Spray Foam Insulation Blocks Heat, Air & Moisture 

Spray foam insulation is one of the best types of attic insulation because it acts as a moisture and air barrier as well as an insulator. When properly installed by a professional spray foam insulation contractor, spray foam insulation will keep your attic cool and dry during the summer, leading to benefits like: 

  • Energy savings 

  • Improved comfort 

  • Lower humidity levels 

  • Less risk of mold growth
