Premium Material: The KINGXBAR ember mat is made of three heat-resistant fabrics: a flame-retardant cotton layer, fire-resistant aluminum foil, and silicone-coated fiberglass fabric, which has a heat resistance of up to 1800 degrees. You will find that it reflects heat so well that it is cool to the touch without burning. Protect Your Lawn: Thanks to the advanced aluminum foil layer, the KINGXBAR fire pit mat reflects 96% of radiant heat to protect the grass from dying from heat. Whether your surface is wood, composite, stone, or concrete, our fire pit mat will protect your patio from burns, heat damage, heat deformation, grease spills, cement stains, and more. Versatile Heat Protection: 91 cm fireproof mats have a versatile round shape designed as an underlay for larger propane fire pits, campfires, burn barrels, fire rings, charcoal grills, smokers, or outdoor chimeneas, etc. It is perfect for most home-use fire pits. Use 2 or more fire pit mats for a larger size. Warning: Ensure there must be at least 10 cm of space between the heat source and the mat for proper heat protection. The fire pit mat is NOT recommended to come into direct contact with the fire pit. Size: 91 cm Weight: 680 g Packing list: 1 x Fire Pit Mat
