Spray Foam Your Home in Summer: Cut Your Energy Cost Significantly

When summer hits New England, so do high electric bills and uncomfortable indoor temperatures. If your home still struggles to stay cool despite cranking up the AC, the problem may not be your HVAC system — it could be your insulation.

At Custom Insulation Company, Inc., we help homeowners take control of their energy use with spray foam insulation — a powerful solution that does more than just insulate. In fact, it’s one of the most effective ways to stay cool and cut costs during the summer.

Air Sealing: The Summer Superpower

Unlike traditional insulation, spray foam expands to fill gaps, cracks, and crevices, creating a tight seal that blocks out hot, humid air. This air sealing effect is key in the summer, where even the smallest leaks can let in heat and force your AC to work overtime.

By keeping the cool air inside and the hot air out, spray foam allows your cooling system to run more efficiently — and your energy bills to drop.

Benefits of air sealing in summer:

• Keeps indoor temps consistent throughout the day
• Reduces humidity inside your home
• Helps HVAC systems run less frequently and last longer

Reduce Solar Gain = Less Overheating

Solar gain — the increase in temperature from sunlight streaming through your roof and walls — can turn attics into ovens. Spray foam insulation minimizes solar heat gain, especially in attics, crawl spaces, and exterior walls.

By reflecting and resisting heat transfer, spray foam helps:

• Lower attic temperatures by up to 30°F
• Prevent that “heat radiating from the ceiling” effect
• Protect stored items and ductwork in attic spaces

Lower Bills, Higher Comfort

Most of our customers report a 20-40% reduction in cooling costs after installing spray foam insulation. It’s not just about comfort — it’s a long-term investment that pays for itself through energy savings.
