How Home Insulation Works in the Summer

Although insulation’s claim to fame is keeping your home warm during the winter time, what some people don’t know is that insulation is rather beneficial during the summer season as well. The same principles that help our house stay warm in the winter are also what helps our houses stay cool in the summer.

Attic Insulation

During hot summer days, the sun’s rays radiate into our houses the strongest and heat up our roof and walls. This sweltering heat enters the home and causes things to become quite warm and uncomfortable.

The temperature in our houses, particularly in the attic, can rise up to nearly 170 degrees on a hot day. As a solution to beat the heat, homeowners will then run the air conditioning system all day to cool their house down. And we all know that air conditioning entails cost.

So, a better solution to this problem would be to reduce the heat load and block the heat from entering your home.

Installing insulation can effectively prevent your home from overheating. This will also prevent you from spending so much money on energy costs in keeping your house temperature regulated for your comfort.

When your house is properly insulated, it will stay cooler longer into the day. Also, the air conditioning will run much less often. So, energy consumption will be much lower.

To under­stand how and why insu­la­tion works well in both warm and cold weather, let’s take a look at how insu­la­tion actu­ally works.

How Does Insulation Work?

Insulation is a thermally resistant barrier that prevents heat flow. It limits the movement of thermal energy around the house. Basically, it works by blocking the heat from coming into the house during summer and keeps the heat within the house during winter.

Insulation makes it possible to have a cooler home in the summer and a warmer home in the winter. And consequently, lower energy bills!

Insulation types like fiberglass and exterior wall insulation block heat flow by holding small air bubbles within the material. It prevents heat from transferring across the insulation materials forming the barrier.

Insulation

The air pockets have good insulation properties because the air is unable to move around.

It doesn’t mat­ter if it is warmer out­side than inside, or colder out­side because the warm air is not going to travel across that bar­rier. However, fiberglass insulation, for instance, isn’t always leak-proof. So, air could still get in or out.

On the other hand, foil insulation can also provide insulation by using a different mechanism.

The reflective surface of the soil functions as an insulation by deflecting the heat back to the source and preventing it from getting into the rest of your home. Ideally, it is useful for spaces outside the home, such as the loft or rooftop, or in combination with bulk insulation.

So, What’s The Best Insulation For My Home This Summer?

Each type of insulation functions to achieve a level of energy efficiency by helping to slow the movement of the airflow and retain heat. Some are more effective than others, depending on your space and needs.

There are plenty of options in the market so that you can make the best choice for your home, such as:

How Do I Prevent My Home From Overheating in the Summer?

Experts recommend air sealing and insulation. Air sealing ensures that hot or cold air does not go in and out of your home, keeping the temperature in your home regulated.

Increasing insulation is recommended in a variety of places, such as:

  • Areas that lack insulation
  • Areas with poorly installed insulation
  • Areas without thick enough insulation
  • Exterior walls or floors over unheated spaces

What Are The Different Types Of Home Insulation?

  • Roof Insulation

It helps to maintain a cool atmosphere in your home regardless of the season, especially if the air conditioning unit is in the attic or if your attic serves your storage purposes.

  • Ceiling Insulation

Adding or enhancing insulation in the ceiling provides temperature and sound control.

It helps in keeping the temperature throughout your home at a comfortable level.

Insulating and sealing the attic properly is one of the best ways to ensure that hot or cold air won’t get in your house. When the air inside your home gets heated, it rises and escapes through the gaps in the attic. So, insulating your attic can also save you a lot of money on energy bills any season.

  • Duct Insulation

Insulating and sealing ductwork also helps in controlling the temperature and minimizing energy consumption. In most houses, uninsulated ducts are in the basement, attic, or crawl spaces.

  • Crawl Space Insulation

When crawl spaces are not properly sealed and insulated, damp air finds its way into your home. Over time, this can create a damp environment that ruins air quality and brings discomfort. It also encourages mold growth or wood rot due to moisture entry.

  • Some Notes On Home Insulation

Fiberglass Insulation

Insulating the key areas of your home creates a barrier that prevents heat from entering your house on a hot, humid day. But homeowners should also realize that it is also important to air seal their homes as well for achieving optimal energy efficiency in their home.

All areas must be properly insulated, even the attic, to improve the energy performance of your home. Because when one part of the home is changed or improved, the effects can be noticed throughout.

Insulation Is More Than a One Season Solution to Your Home Comfort

It requires a lot of energy (and money!) to heat or cool your home. This is why insulation is a good investment in dealing with the conditions that could arise from a leaky home.

Whether it’s summer or winter, insulation works well in both seasons in keeping your home’s temperature regulated for your comfort. Insulation helps you achieve energy efficiency and comfortable house temperature.
