Radiant Barriers
Radiant Barrier Insulation in the Finger Lakes & Upstate NY
Keep Your Home Cooler, Reduce AC Costs & Improve Year-round Comfort
Radiant heat from the sun can turn your attic into a 120 degree oven — forcing your air conditioner to work overtime and driving up your energy bills. A properly installed radiant barrier from AB Insulation reflects this heat away from your home, dramatically improving comfort and reducing cooling costs.
​
Our radiant barrier systems are engineered for performance, installed by certified technicians, and designed to work seamlessly with your attic insulation for maximum efficiency.
What Is a Radiant Barrier?
A radiant barrier is a reflective insulation material — typically a foil-faced product — installed in your attic to reflect radiant heat rather than absorb it. While traditional insulation slows heat transfer, radiant barriers bounce heat away, keeping your attic significantly cooler.
Radiant barriers can:
-
Reflect up to 97% of radiant heat
-
Reduce attic temperatures by 20–30°F
-
Lower AC usage and cooling costs
-
Improve comfort in every room of the home
This technology works much like the reflective windshield shades used in cars — but on a much larger, more effective scale.
Why Your Attic Gets So Hot
If you’ve ever opened your car door after it sat in the sun, you’ve felt the power of radiant heat. The same thing happens in your attic:
-
Sunlight hits your roof
-
Radiant energy transfers into the attic
-
Temperatures climb to 120°F or higher
-
Your AC runs longer and harder to compensate
A radiant barrier stops this heat before it enters your living space.
How Radiant Barriers Work
Radiant barriers are installed along the underside of your roof or over existing insulation. Their reflective surface:
-
Blocks radiant heat from entering the attic
-
Reflects heat outward during summer
-
Reflects indoor heat back downward during winter
-
Works year-round to improve energy efficiency
When combined with proper attic insulation and air sealing, radiant barriers create a powerful thermal defense system.
Benefits of Radiant Barrier InsulationÂ
Homeowners in Upstate NY can expect:
✔ Lower Cooling Costs
Radiant barriers can reduce AC usage by 10% or more, especially in homes with ductwork in the attic.
✔ A Cooler, More Comfortable Home
Lower attic temperatures mean less heat radiating into your living space.
✔ Improved HVAC Performance
Your AC doesn’t have to fight against extreme attic heat.
✔ YearRound Energy Savings
Reflective surfaces help retain heat in winter and block heat in summer.
✔ Works With Existing Insulation
Radiant barriers enhance — not replace — your current insulation system.
Choosing the Right Contractor Matters — A LOT
Radiant barriers only perform as promised when they are installed correctly. Poor installation can:
-
Trap moisture
-
Reduce attic ventilation
-
Create condensation issues

Shorten the lifespan of your insulation system
This is why choosing a qualified contractor is absolutely essential.

Frequently Asked Questions & Answers
​
Do radiant barriers work in New York’s climate?
Yes. While radiant barriers are extremely effective in hot climates, homes in Upstate NY still benefit from reduced attic temperatures, lower AC usage, and improved winter heat retention.
How much can a radiant barrier save on energy bills?
Most homeowners see 10% or more savings on cooling costs. Homes with attic ductwork often see even greater savings.
Can a radiant barrier be installed over existing insulation?
Absolutely. Radiant barriers are designed to work with your current insulation, not replace it.
Will a radiant barrier help in winter?
Yes. The reflective surface helps keep heat inside your home by reflecting it downward, improving winter efficiency.
Is a radiant barrier the same as insulation?
Not exactly. Traditional insulation slows heat transfer; radiant barriers reflect heat. Together, they create a highperformance thermal system.
How long does installation take?
Most radiant barrier installations can be completed in one day, depending on attic size and accessibility.
Why is it important to hire a certified installer?
Improper installation can reduce effectiveness, cause moisture issues, or interfere with ventilation. Certified technicians — like those at AB Insulation — ensure the system performs exactly as intended.
Does a radiant barrier affect attic ventilation?
When installed correctly — which AB Insulation guarantees — radiant barriers work seamlessly with attic ventilation systems.
