The Problem

YOUR ATTIC IS
COSTING YOU MONEY

On a 95°F summer day, your roof deck can hit 165°F. That heat pours straight into your attic — and then into your home. Your AC fights it nonstop. And you pay for every degree.

🌡

Roof heat is invisible — but costly

Up to 40% of unwanted heat gain in a home comes through the roof as infrared energy. It doesn't matter how much wall insulation you have — attic heat travels right past it.

Your AC is working twice as hard

The hotter your attic, the harder your air conditioner runs. Studies show that attic heat alone can add 25–40% to your cooling load — that's hundreds of dollars a year.

😓

Rooms never feel quite comfortable

Top-floor rooms run 5–10°F hotter than the rest of the house. Your system cools to the thermostat — but heat pouring in from above makes it feel like it never quite gets there.

🔧

HVAC wears out faster

Every extra hour your system runs is wear on the compressor, motor, and refrigerant. Shorter runtime means less maintenance, fewer breakdowns, and a longer equipment life.

The Solution

ONE BARRIER.
ALL THE DIFFERENCE.

ThermalGuard's reflective foil barrier installs in your attic rafters and bounces heat back before it ever enters your home. Simple physics. Measurable results.

1

Roof heat hits the foil surface

When infrared radiation from your scorching roof deck reaches ThermalGuard's aluminized surface, up to 97% of it is reflected back — not absorbed, not transferred.

2

Attic temperature drops dramatically

With heat blocked at the source, your attic can run 20–30°F cooler on hot days. That's the difference between a 140°F oven and a manageable 110°F space.

3

Your AC runs less — your bill falls

A cooler attic means less heat bleeding into your living space. Your thermostat reaches setpoint faster, your compressor cycles less, and your energy bill shrinks.

4

Works with what you already have

ThermalGuard doesn't replace your existing insulation — it supercharges it. Adding a heat barrier on top of R-30 insulation outperforms R-60 alone in hot climates.

Energy savings estimates based on Department of Energy and Florida Solar Energy Center studies on reflective heat barriers in Climate Zones 1–3. Individual results vary based on home size, insulation level, HVAC efficiency, and local utility rates.

Home Comfort

FEEL THE DIFFERENCE
IN EVERY ROOM

Savings on your bill is just the beginning. The real reward is a home that actually feels comfortable — every floor, every room, every day of summer.

🛏

UPSTAIRS BEDROOMS

Top-floor rooms run 5–10°F cooler after installation. No more stifling bedrooms, no more fighting over the thermostat, no more sleeping with fans pointed at your face.

8°FCooler upper floors on average
❄️

CONSISTENT TEMPS

Hot spots and cold spots come from uneven heat load. ThermalGuard levels the playing field — your AC reaches setpoint across the whole house, not just near the vents.

QUIETER AC SYSTEM

When your AC runs less, you hear it less. Shorter, less frequent cycles mean a quieter home — and a system that isn't racing to keep up with constant heat infiltration.

30%Fewer AC cycles per day

LOWER HUMIDITY

Heat and humidity travel together. A cooler attic means your AC doesn't have to remove as much moisture from the air — giving you drier, more comfortable air all season.

YEAR-ROUND BENEFIT

In winter, double-sided ThermalGuard reflects heat back down into your living space — reducing heating costs too. One installation works every season.

OUR WORD FOR IT

Over 50,000 homes equipped. Here's what customers say after their first full summer with ThermalGuard.

★★★★★

"I was skeptical. Foil in the attic sounded like snake oil. Then my July electric bill came in — $74 less than last year, same thermostat setting. By end of summer I'd saved over $200. I'm a believer."

Marcus T.
Phoenix, AZ · 2,100 sq ft home
★★★★★

"The upstairs bedrooms used to be 10 degrees hotter than downstairs. After ThermalGuard, my kids actually sleep in their rooms again. It's transformed the house."

Jennifer R.
Tampa, FL · 1,650 sq ft home
★★★★★

"Installed it myself in about 4 hours. The staple gun was the hardest part. My energy monitor showed the AC cycling less within the first week. Incredible value."

Common Questions

YOU'VE GOT
QUESTIONS.

It works — and the physics are simple. Heat travels through air as infrared radiation. Aluminum reflects infrared. ThermalGuard is 97% pure aluminum laminate. The Department of Energy, NASA research, and independent Florida Solar Energy Center studies all confirm that reflective heat barriers reduce attic heat gain by 25–40% in hot climates. It's not magic — it's material science.
Yes — and here's why: insulation slows conductive heat transfer. ThermalGuard blocks infrared heat transfer. They address completely different heat pathways. Research shows that adding a reflective barrier to existing R-30 insulation outperforms upgrading to R-60 alone in hot climates. They work together, not instead of each other.
Not with our perforated foil — and that's why we sell perforated, not solid. The micro-perforations allow vapor to pass through freely, preventing any moisture buildup. Solid foil barriers can create moisture issues; ours are specifically engineered to prevent them. As long as your attic is properly ventilated (soffit and ridge vents clear), you'll have zero moisture concerns.
Most homeowners in warm climates see full ROI within 5–7 years. At 20–25% savings on a typical $320/month electric bill, you're saving $64–$80 every single month. In peak heat climates like Phoenix, Houston, and Tampa, many customers fully recoup their investment in the first summer alone. After that, every dollar saved is pure return — for the next 23+ years of the product's warranted life.
No — our double-sided TG Double-Sided product reflects heat in both directions. In winter, it reflects heat back down into your living space instead of letting it escape through the roof. This provides meaningful heating savings in addition to the primary cooling benefit. Single-sided products are optimized for warm climates where cooling costs dominate.
