Common Summer Energy Wasters and How Spray Foam Insulation Can Fix Them

When summer hits, your cooling system goes into overdrive and so does your energy bill. But what many homeowners don’t realize is that the real culprit behind high energy costs might not be your AC at all. Leaks, gaps, and outdated insulation are silently draining your home’s energy and comfort. Fortunately, spray foam insulation is a powerful solution that can seal your home and save you money.

1. Air Leaks Around Windows and Doors

Small cracks and gaps around windows and doors may seem harmless, but they’re major energy wasters. In the summer, hot air seeps in and your cooled air escapes forcing your AC to work overtime.

 

How Spray Foam Helps:
Spray foam expands to fill every gap, creating an airtight seal that traditional weather stripping or caulking can't match.

2. Attic Heat Transfer

An under-insulated attic becomes a heat trap in summer. That trapped heat radiates down into your home, making it harder to keep your space cool.

 

How Spray Foam Helps:
By applying spray foam to the roofline or attic floor, you block radiant heat, dramatically reducing attic temperatures and cooling costs.

3. Poorly Insulated Walls

In many older homes, walls lack proper insulation or any insulation at all. This allows heat to move freely between inside and outside, reducing your home’s overall efficiency.

 

How Spray Foam Helps:
Spray foam insulation is ideal for retrofitting wall cavities, offering both high R-values and a tight seal to prevent air movement and thermal bridging.

4. Basement and Crawl Space Gaps

Don’t overlook your foundation. Gaps and leaks in basements or crawl spaces allow hot, humid air to infiltrate your home and can lead to uneven temperatures and higher energy use.

 

How Spray Foam Helps:
Spray foam insulation in your basement rim joists or crawl space walls helps condition these forgotten zones keeping your entire home cooler and drier.

5. Leaky Ductwork

Even if your attic or walls are well-insulated, leaky ducts can waste up to 30% of your cooled air before it even reaches your living space.

 

How Spray Foam Helps:
While not applied directly to ducts, spray foam creates a more controlled building envelope reducing temperature extremes and easing the load on your HVAC system.

Seal the Gaps, Save Big

Energy waste isn’t always obvious, but it adds up quickly especially in the heat of summer. Spray foam insulation is one of the most effective ways to seal your home, reduce energy bills, and keep your indoor climate consistently comfortable. Whether it’s in the attic, walls, or basement, the airtight, high-performance nature of spray foam makes it a smart investment for long-term savings.
