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.
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:
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:
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.
Don’t let another summer drain your wallet or your AC. Let Custom Insulation Company, Inc. show you how spray foam insulation can transform your home into a cooler, more efficient space.
