Will Insulation Keep My Home Cool?

With summer in full swing in Louisville, you may be wondering what else you can do to keep your home cool without continually cranking up the air conditioning. Simply relying on your AC will put excessive wear and tear on your unit in addition to causing your electric bill to skyrocket. The solution to keeping your home cool during the summer, apart from air conditioning, is insulation and air sealing.

Benefits of Insulation During the Summer

You may have heard that insulation is like “a sweater for your home.” While that is the case, it’s actually much more than that. Insulation does in fact keep your home warm during the winter, but it’s also vital to keeping your house cool during the summer.

How does that work? Well, insulation, in conjunction with air sealing, works to inhibit heat flow. Since the natural inclination of heat is to go from a warmer area to a cooler area, heat will try to invade your home during the summer, and escape during the winter. Insulation and air sealing reduce this from happening.

How exactly will insulation work together with your AC to keep your home cool during this hot, humid Kentucky summer? We’re glad you asked!

Insulation: Keeping the Heat Out

As you’ve already learned, heat likes to move from warmer places to colder ones. So that actually means that your indoor air-conditioned air isn’t exiting your home, it means that hot, humid outdoor air is entering.

Your home’s building envelope is the boundary between indoor and outdoor space. The walls, ceilings, floors, doors and windows are part of the building envelope, and they act to keep the air inside, also referred to as the “pressure boundary”. The insulation materials inside the walls, ceilings, windows, doors, etc. are what make up the “thermal boundary”, and they work to resist the transfer of heat across the building envelope.

The pressure and thermal boundaries are reliant on each other to function properly, and you cannot have a comfortable, efficient house unless they are working properly together.

So How Do I Keep the Heat Out?

You need to air seal all the little holes, cracks, and gaps you can find first, then have a quality insulation product installed by a well-trained company.

Insulating and air sealing your home’s building envelope properly will work to keep hot, steamy summer air out of your house, keeping you cool and comfortable.

Preventing AC Burnout

If you don’t have insulation, if it’s of poor quality or if your home isn’t air sealed, you are probably constantly lowering the thermostat on your AC. Presumably, it’s not helping much.

Putting so much stress on your air conditioner can shorten its lifespan and influence the indoor air quality (IAQ) of your home. With your air conditioner constantly running at full blast, the filter is likely to build up with dust, allergens and other unpleasant particulates. Without cleaning or replacing your air conditioner’s filter regularly, your IAQ will soon become poor, and eventually even dangerous.

Lowering Your Energy Bills

Proper insulation and air sealing will prevent you from having to rely as heavily on your air conditioning unit. By running your AC less (or at least on a less powerful setting) your energy usage will greatly decrease. Using less energy to power your air conditioning results in lower energy bills and helps you save money while having a cooler, more comfortable home.

Increased Comfort in the Winter

In addition to increasing the comfort of your home during the summer, insulation and air-sealing will ensure you experience similar benefits during the winter. You’ll have a warmer, cozier home during the cooler months and will undoubtedly spend significantly less money on your heating costs.
