Summer turns up the heat, which means your energy bills are sure to follow. If you’re tired of running the AC nonstop and paying excessive energy bills without much relief, you could benefit from better insulation. Spray foam is the best option out there, but why? Let’s break it down.

Spray Foam Blocks Heat Gain

Spray foam insulation creates a tight thermal barrier that resists heat transfer better than traditional materials. Closed-cell spray foam delivers an R-value of R-6 to R-7 per inch—almost twice that of fiberglass or cellulose—making it ideal for keeping heat out during the summer. Plus, it expands on contact, sealing up gaps that other materials leave behind.

Spray Foam Seals Air Leaks

Summer heat loves to sneak in through the attic floor, around exhaust vents, and through exterior walls. Spray foam insulation eliminates these pesky leaks and prevents hot spots by creating an airtight seal. Unlike fiberglass or cellulose, spray foam doesn’t leave weak points where air can slip through. Even if you choose another insulation type, sealing air leaks with spray foam first is still recommended.

Spray Foam Stops Moisture Intrusion

The Chicago humidity is no joke. Spray foam insulation protects your home against moisture buildup, which means fewer issues with mold growth and musty air. If you choose another insulation material, you’ll need to add a separate vapor barrier to achieve the same results.

Spray Foam Cuts Energy Bills

Many Chicago-area homeowners choose spray foam insulation to lower their utility costs. Your air conditioner doesn’t have to run as often when your home is well-insulated, so you’ll notice a drop in your monthly bills immediately. In this way, your investment pays you back all summer long.

Spray Foam Is Built to Last

Loose-fill insulation can settle, batts can shift, and most traditional materials lose their insulating power when wet. Spray foam avoids all these problems. It holds its shape, stays in place, and performs flawlessly for years—no re-fluffing, re-packing, or replacing needed.

Spray Foam FAQs

Does spray foam insulation help in the summer?

Yes, proper insulation does its job year-round. In the summer, spray foam prevents outdoor heat and humidity from infiltrating your home, keeping indoor temperatures more stable and lowering cooling costs.

Does spray foam help with heat?

Absolutely. Spray foam insulation is one of the most effective ways to reduce heat transfer. The closed-cell variety is particularly effective at blocking heat, allowing your AC to run less.

Why use spray foam insulation instead of something cheaper?

Spray foam is more costly upfront, but it outperforms other types of insulation in every category: thermal resistance, air sealing, durability, and moisture protection. It’s the modern solution for staying cool, saving money, and reducing headaches.
