How It Works

FireFoil Wildfire Ember & Fire Shields™ are patent-pending, aluminum-based shields designed to protect your home from the three leading causes of wildfire structure loss:

  • Radiant heat
  • Convective heat
  • Burning embers

Our shields act as a temporary armor layer, reflecting heat and blocking embers long enough for the fire front to pass. FireFoil is reusable, chemical-free, and used by professional firefighters and homeowners alike.

The shields trace their lineage directly to the fire shelters that are mandatory safety equipment for all wildland firefighters facing life-threatening fire entrapment.


How FireFoil Works

FireFoil reflects 96.5% of radiant heat and significantly reduces convective heat exposure, drastically reducing the chance of your home igniting.

Independent testing showed:

  • Wood beneath the shield remained below 188°F after 10 minutes of intense radiant exposure.
  • This is far below the autoignition threshold of 575°F, where wood off-gases and can ignite from a spark.

Our shields importantly provide professional-grade defense against flying embers—which cause 80–90% of home ignitions. These hot firebrands, traveling up to 2 miles, either slide off or burn out harmlessly on FireFoil surfaces.

What are embers, radiant heat and convective heat?

Embers or “firebrands" are small, glowing pieces of burning material that can travel more than 2 miles ahead of the main fire front, easily bypassing even well-maintained defensible space. According to the IBHS, embers are known to cause up to 90% of structure ignitions.

Radiant heat is what you feel when you are sitting in front of a fire in a fireplace. During wildfires, radiant heat can become intense enough to shatter windows, creating openings that allow embers to enter and ignite the interior of a structure.

Convective heat is what you feel when you sit beneath a heating or cooling vent. During wildfires, it preheats structures, drives flames into vulnerable areas, and carries embers.

    Our Products

    We sell shields and rolls. If you'd like to see our entire product line

    • Shields: Large-format configurations measuring up to 20 feet wide by 100 feet long, ideal for rapid deployment of medium to large structures
    • Rolls: Budget-friendly, measuring 5 feet wide by up to 300 feet long, ideal for smaller or more targeted applications

    We offer multiple levels of protective materials, tailored to match the threat level of a wildfire and the importance or vulnerability of the structure being protected.

    At the top of our product line is L140, our most robust and heat-resistant shield, engineered for maximum durability and protection in extreme wildfire conditions. For less intense scenarios, we offer options such as L30, which provides reliable defense at a more accessible price point while still meeting the performance standards required for effective protection.
