Kamado Joe · Grill & Oven Mats
Barebones Fire & Grill Mat Mini
Lower PFAS concern; standard fiberglass grill mat with no identified Teflon-family coating.
The Kamado Joe Barebones Fire & Grill Mat Mini is a fiberglass mat used for heat protection under grills. Fiberglass mats typically use silicone bonding rather than Teflon-family coating coatings, placing them at lower risk for PFAS exposure compared to nonstick cookware or water-repellent coating-treated fabrics.

The full breakdown
What it's made of and why it matters
The Barebones Fire & Grill Mat Mini is a fiberglass-reinforced silicone mat designed to protect surfaces under high-heat grilling. Fiberglass provides structural integrity and thermal stability, while silicone binder allows flexibility and non-stick properties without relying on Teflon-type coating (Teflon) or other Teflon-family coating. At typical grill temperatures (below 500°F for the mat itself), silicone does not off-gas hazardous fumes, though fiberglass can shed microfibers if the surface becomes damaged or abraded over time.
The brand's record and disclosure
Kamado Joe has not published detailed material safety data sheets or third-party certifications (e.g., FDA food-contact clearance, CPSC compliance statements) for this specific product in publicly available sources. The brand has maintained a silent stance on PFAS use across its product line, which is typical for cookware and grill accessory manufacturers but limits transparency. No major recalls or safety complaints linked to this mat model have been documented in CPSC or consumer databases as of current public record.
How it compares in its category
Fiberglass-silicone mats occupy the mid-to-premium segment of grill mats; they are more durable and heat-resistant than vinyl or rubber alternatives but shed microfibers more easily if scratched. Many competitors use similar silicone-fiberglass construction without Teflon-type coating, making this product compositionally standard for the category. The 'Mini' size suggests a niche accessory rather than a full-coverage mat, which reduces total fiberglass exposure compared to larger mats.
If you buy it
Keep the mat surface intact by avoiding sharp tools or abrasive contact; inspect regularly for cracks, peeling edges, or loose fibers. Use it on flat, stable surfaces and keep it away from direct flame (fiberglass can char if exposed to 700°F+). Replace the mat if the silicone separates from the fiberglass backing or the surface becomes heavily abraded. Clean with mild soap and water; do not immerse for extended periods, as moisture can weaken the fiberglass-silicone bond over years of use.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Fiberglass microfiber shedding
Silicone-fiberglass mats can release airborne microfibers if the surface is punctured, torn, or abraded. Inhalation risk is low during normal use on intact mats but increases if the mat degrades; ensure good ventilation if damage occurs and dispose of worn mats safely.
Silicone binder thermal stability
High-grade food-contact silicone is thermally stable up to 400-500°F without documented off-gassing. This product is a surface mat (not direct food contact), but sustained exposure above 600°F may degrade the silicone binder; no known toxicity reports for typical grill use exist.
Mold and bacterial growth
Porous fiberglass structure can trap moisture and organic debris if stored damp or not fully dried after cleaning. Visible mold or odor signals need for thorough drying and potential replacement; rinse and air-dry completely after each use in humid climates.
Lead or cadmium in mineral fillers
Industrial silicone and fiberglass are not known to contain lead or cadmium in this application, and Kamado Joe products are not flagged in public contamination records. No independent testing of this specific mat has been published.
VOC off-gassing from silicone curing
New silicone-fiberglass mats may emit slight odor for the first few heating cycles as residual monomers volatilize; this odor is not associated with toxic compounds under standard manufacturing, but airing out the mat before first use is a reasonable precaution.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
