Have you ever walked into your home on a hot July afternoon and thought, “Why is it hotter inside than outside?”
If that sounds familiar—you’re not alone. Every summer, we hear from New Jersey and Westchester homeowners who are frustrated with high cooling bills and rooms that just won’t stay cool. You crank the A/C, shut all the blinds, and still… the heat wins.
At Metro NY Insulation, we get it. Did you know spray foam insulation stops summer heat before it ever enters your home.
Let’s break down exactly how it works.
Why Spray Foam Insulation Stops Summer Heat
Most insulation just slows the transfer of heat. But spray foam insulation?
It goes a step further by blocking airflow and sealing your home completely.
Here’s why that matters during summer:
Seals Air Leaks: Spray foam insulation expands to fill every crack and gap—especially in attics, crawl spaces, and rim joists. That means hot summer air stays out, and your cool, conditioned air stays inside.
Creates a Thermal Barrier: Instead of gaps or compressed batts, spray foam forms a continuous, airtight shield that resists radiant heat from the sun.
Reduces A/C Load: When your home is sealed tight, your air conditioner doesn’t have to fight to keep up. That means lower cooling costs and better temperature control all season long.
When it comes to spray foam insulation, summer heat doesn’t stand a chance.

Real Story: From Sweltering to Satisfied
One customer in Bergen County told us their upstairs bedrooms were unbearable every July.
We installed closed-cell spray foam insulation in the attic and sealed the rim joists. Their exact words?
“It felt like night and day. Our bedrooms used to hit 85°, but now they stay cool and comfortable—even in the middle of the day.”
It’s one of the biggest summer upgrades you can make.
Spray Foam Insulation = Real Energy Savings
Let’s talk dollars and cents.
The Department of Energy estimates that up to 30% of a home’s cooling energy is lost through air leaks and poorly insulated spaces.
With spray foam insulation, summer heat is locked out—so your cooling system works less and lasts longer. That means lower energy bills, fewer breakdowns, and more peace of mind.
Even better?
If you live in New York, you may qualify for state energy rebates that help cover the cost of spray foam upgrades.
We’re a top-rated BPI-accredited, NYSERDA-participating contractor, and we’ll handle the rebate paperwork so you don’t have to.
