Pro Tip
Some insurance companies in high-risk wildfire zones routinely knock 10-30% off premiums when you switch to Class A metal siding. One customer in Boulder paid for his entire re-side job with three years of savings.
Why American Homes Need Real Fireproof Siding Now
Wildfires no longer stay “out west.” In 2024 alone, states from Oregon to New Jersey watched flames jump highways and torch entire neighborhoods. Traditional vinyl siding melts at 165°F and feeds the fire. Wood shakes turn into kindling. Fiber cement cracks and still allows flame spread under the right (wrong) conditions.
Steel refuses to play that game. Zero fuel, zero flame spread, zero melted mess dripping down your walls. Builders in California now face mandates for non-combustible exteriors in many zones, while the rest of the country catches up fast because insurance companies draw hard lines.
What Class A Fire Rating Really Means (and Why Most “Fire-Resistant” Claims Are Marketing Fluff)
A true Class A rating comes from ASTM E108 or UL 790 testing. Technicians set the roof (or wall assembly) on fire with flaming brands, then crank gas burners to 1400°F for hours. Class A means flame spread stays under 6 feet and no flying embers ignite the material.
Steel panels from BarrierBoss earn the only rating that matters: non-combustible under ASTM E136. Translation: the siding itself will not burn, period. Many competitors slap “Class A” on fiber cement or treated wood that still allows flame spread in real-world winds. Steel laughs at those conditions.
Did You Know?
The 2018 Camp Fire in Paradise, California destroyed over 18,000 structures. Investigators found metal-roofed homes with steel siding survived at ten times the rate of everything else, even when wooden homes ten feet away turned to ash.

FAQs About Fireproof Metal Siding
Does metal siding get hotter than other materials in summer?
No evidence shows lived-in homes with proper ventilation notice any difference. Light colors reflect heat anyway.
Will it dent if my kid nails it with a baseball?
26-gauge steel handles everyday life. You only need 24-gauge if you coach Little League in the backyard.
Can I install it over existing siding?
Yes in most cases. Furring strips create a rain screen and flat surface.
Does BarrierBoss ship to Alaska and Hawaii?
BarrierBoss ships to the lower 48, but we have these States in our sights!
How long does the finish last?
BarrierBoss finishes carry 30-year warranties against fading and chalking.
