Upgrade 3 layers and thicker - The first layer of aluminized fiberglass fabric reflects up to 95% of the heat from the fireplace. The second layer of heat insulating cotton helps isolate heat and slow down the transmission. The third layer of silicone-coated fiberglass improves the thermal insulation effect and is non-slip. 2. Portable - Charcoal fires can cause irreparable damage to the deck and lawn. A fire retardant, heat resistant fire pit mat is perfect 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. 3. Fit for 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 mat is here to keep you safe. However, for the best results, all four legs of the fire pit should be on the mat. 4.Warm tips - DO NOT place the heat source directly on the fire-resistant surface, there should be at least 10 cm of space between the fire mat and the heat source. If you want to use the fire pit mat without legs under the fire pit, please use a stand. Please keep the reflective layer (aluminized layer) facing up. 5.Waterproof and Durable - Our fire bowl mat is waterproof to withstand the rain. In the meantime, you can also easily remove grease, mud and other stains from the fireplace mat with water and a towel. The high quality materials ensure a long service life, so you can enjoy the warmth and comfort of the fireplace on the deck.
