With temperatures rising and summer just around the corner, it’s about time to turn on the AC.  Have you ever noticed even with your AC on full blast, you can still feel hot in your home?  That may have nothing to do with your HVAC and a lot to do with how well your home is insulated.

So, before investing in AC repairs or a new HVAC system entirely, consider these possibilities for why your home isn’t staying cool.

Poorly Insulated Floors and Walls

Poorly insulated floors and walls are one of the biggest culprits when it comes to air flowing out of your home.  It’s estimated that up to 35% of air leakage from a home occurs through the floors and walls.  Not only does properly insulating floors and walls keep you comfortable, it can also lead to significant decreases in your heating and cooling costs.

Windows and Doors

Windows and doors naturally get worn down by opening and closing, as well as by fluctuations in temperature.  Even a tiny crack in a window or door can lead to major air leakage.  A study referenced in the Washington Post found that a 1/8 inch gap under an exterior door can let as much air in or out of your home as a 2.4-inch-diameter hole punched in the wall.

Inadequate Roof Insulation

The roof is another area of the home that is notorious for allowing air flow in and out.  If you’ve ever been in a poorly-insulated attic on a summer day, it’s easy to understand how a poorly insulated roof can have drastic temperature impacts in your home.  As hot air enters the home, it displaces cold air.  Unless there is a barrier preventing hot air from entering the home, cold air will escape through your roof and other exterior areas of your home.

How Can Spray Foam Insulation Help?

Spray foam insulation creates a barrier between your home and the outside, preventing unwanted air leakage.  Because spray foam is initially applied as a liquid and then expands, small cracks and crevices in your walls and roof can be easily filled.  This makes spray foam insulation superior to traditional insulation types, such as fiberglass or cellulose, which often leave openings that allow air flow.

If you’re having trouble keeping your home cool in the summer, have a professional check the insulation in your home to ensure it’s up to code.
