How Does Insulation Work in the Summer?: A Complete Guide

With summer temperatures bringing sweltering heat, efficient insulation can prevent your home from overheating. While winters are long and cold, summer can bring tremendously high humidity and temperatures. It takes a lot to cool your home during the summer, so insulation is a significant investment when dealing with conditions that could arise from air leaks.

To trap cool air in your home and lower energy costs, it’s essential to have efficient insulation, so whether in your attic or crawl space, this is one area you don’t want to skimp out on. Below, we’ve constructed a guide that covers why your home gets hot during the summer, signs of insulation problems, how insulation can help your HVAC system, and the best insulation to keep your home cool.

Why Does My Home Get Hot During the Summer?

Many homeowners view insulation as a way to keep them warm in the winter, and while this is accurate, it’s also an effective way to keep you cool in the summer. Attic insulation can act as a buffer, helping to keep cool air in your home and maintaining a consistent temperature. If you’re heating your home during the winter, insulation will let you keep the warm air indoors, preventing the colder air from coming in.

During the warmer months, the reverse is true. If you’re running your air conditioning during the summer heat, insulation keeps your cool air indoors and the hot outdoor air at bay. Poor attic insulation makes it much easier for cool air to escape and outdoor air to get in, so your home won’t stay cool for long.

Insulation is a must to rectify this issue. Insulation instantly improves the temperatures inside your home, creating a more comfortable environment for you and your loved ones.

5 Signs of Insulation Problems in the Summer

5 Signs of Insulation Problems in the Summer

Whether your insulation problems are from poor insulation or not, here are some likely signs of insulation problems during the summer.

 

  1. Hot Attic – If the second floor of your home and attic are hotter during the summer, this is a sign of poor insulation. While science proves that hot air rises, it enters your home because of inadequate insulation, allowing hot air to rise slowly.
  2. High Humidity Levels – Does your home resemble a sauna during the summer? If this is the case, the humidity levels are likely to blame, so let’s dive into the science. Hot air is less dense than cold air, so it’s easier for moisture to travel with it. If hot air leaks into your home through poor insulation, it’s bringing in moisture, thus making your home hot during the summer.
  3. High Energy Costs—If your monthly energy costs are through the roof during the summer, it’s likely because you have poor insulation. When this happens, your HVAC system is running constantly, trying to keep up to maintain a consistent temperature, which impacts energy costs.
  4. Allergens Move In—It’s that time of year when you notice pollen buildup on the ground and in your car. As hot air leaks into your home, allergens tag along, not making your home’s indoor air quality as healthy as you’d like.
  5. Unwanted Odors—Like humidity levels, hot air is much lighter, and moisture and gases travel with it. One of those gasses is unpleasant odors, such as exhaust or mildew, mainly from outdoors. These unpleasant odors can permeate your insulation, leaving your home smelly. 

Will Insulation Help My HVAC System in the Summer?

Will Insulation Help My HVAC System in the Summe

tatistics from the Environmental Protection Agency suggest that homeowners can save up to 15% on heating and cooling costs by investing in efficient insulation. Here are some benefits of efficient insulation that can help your HVAC system during the summer.

 

  • Keeps cool air indoors—Insulation also prevents cool air from escaping from the lower levels of your home.
  • Maximizes AC efficiency—When hot air stays outdoors, keeping the cool air inside, your AC can operate efficiently without working overtime to cool your home.
  • Lowers heat gains—Insulation can’t protect your roof from the sun but can ensure that heat doesn’t transfer to the rest of your home.
  • Lower energy cost—IF you use your AC less, you’ll lower your monthly energy costs.

An excellent insulation installation is vital, but it also helps homeowners understand the basics so they’re always aware of how improving their insulation can benefit them.
