Material: fiberglassThickness: 0.4mm~6mmHigh temperature resistance range: -50~550Conventional temperature resistance: -50C-550CUpgrade 3 layers or thicker - The first layer of aluminized fiberglass fabric reflects up to 95% of the fireplace heat. A second layer of thermal insulation helps insulate heat and slow down the spread. The third layer is coated with silicone oil glass fiber to improve the thermal insulation effect and prevent slipping. Portable - Charcoal fires can cause irreparable damage to decks and lawns. Flame retardant, heat resistant fire pit mats are ideal for protecting your patio, lawn, composite deck, grass and decorative stone. The lightweight design allows you to conveniently bring the fire pit mat to parties, picnics, camping and barbecues. FITS Most Round Fire Pits - Whether you have a wood fire, charcoal grill, copper bowl fire, portable propane fire or natural gas fire, this fire retardant pad will keep you safe. However, for best results, all four legs of the fire pit should be on the mat. Reminder - Do not place the heat source directly on the fire-resistant surface, leave at least 10 cm of space between the fire mat and the heat source. Use a stand if you want to use a fire pit pad without legs under the fire pit. Please keep the reflective layer (aluminized layer) facing up. Waterproof and Durable - Our fireproof bowl mats are waterproof and resistant to rain. At the same time, you can easily remove grease, mud and other stains from the fireplace mat with water and a towel. Quality materials ensure a long life so you can enjoy the warmth and comfort of the fireplace on your deck. Shipping Quantity: 1 PieceProduct color: silverProduct size: 24*24cm
