THMINS Extra Large Grill Mat 100x51 in — Heat & Grease Resistant Silicone-Fiberglass Barrier

THMINS 100x51-in Extra Large Under Grill Mat is a heavy-duty, high-temperature protective barrier that shields decks, patios and flooring from embers, grease and heat while collecting spills for easy cleanup.

Designed for backyard cooks and mobile entertainers, this extra-large mat combines a fiberglass core with a silicone coating on both sides to resist temperatures up to 2000°F and repel oil and water. At 100 by 51 inches and just 0.02 inches thick, it balances expansive coverage with easy folding and storage, making it practical for home grills, smokers, fire pits and indoor fireplaces alike.

How does this mat protect my deck and patio from heat and embers?

The mat’s high-strength fiberglass fabric and double-sided silicone coating create a durable barrier that blocks embers and redirects radiant heat away from underlying surfaces. While no product can make surfaces fireproof, the THMINS mat is engineered to reduce the chance of scorch marks, smoke stains and hot ash damage.

• Fiberglass core resists high temperatures and maintains shape under heat.
• Silicone coating on both sides prevents direct ember contact with flooring.
• Wide 100x51-inch coverage protects large grill footprints and surrounding zones.
• Thin 0.02" profile stays low to the ground while blocking radiant heat.

Is the THMINS grill mat easy to clean after cooking?

Yes — the waterproof, oil-resistant silicone surface resists grease and food stains so messes wipe away quickly. For routine cleanup, a damp cloth or hose-and-soap rinse restores the mat; for heavier buildup, a gentle scrub keeps it looking new without specialized cleaners.

• Silicone finish repels oil and prevents long-term staining.
• Wipe with a damp cloth for light spills, hose off for heavier residue.
• Quick-dry surface reduces mildew risk when used outdoors.

What sizes and uses work best with this mat?

The large 100x51-inch dimensions suit medium to large grills, smokers, and fire pits and provide extra buffer space for chairs, carts and prep areas. Its thin, foldable design also makes it useful indoors beneath fireplaces or ovens where protective layering is needed.

• Coverage ideal for gas grills, charcoal grills, flat tops and smokers.
• Also compatible with fire pits and indoor hearths for added protection.
• Foldable and thin for portable use at tailgates, camping and events.

How portable and durable is the THMINS grill mat?

At only 0.02 inches thick, the mat folds compactly for storage and travel while remaining tough enough to withstand repeated outdoor use. The combination of fiberglass resilience and silicone coating extends service life under normal grilling conditions, and the mat resists tearing and abrasion during handling.

• Ultra-thin profile folds flat for easy stowing in closets or trunks.
• Reinforced fiberglass resists punctures and wear from ash or grit.
• Durable silicone layer preserves integrity across many seasons.
