NIUNIU Product Description Material: fiberglass Size: 14 inches Thickness: 0.4mm~6mm High temperature resistance range: -50~550 Conventional temperature resistance: -50C-550C Color: silver Quantity: 1 Package Contents: 1 Set * Fireproof Floor Mat 1. Upgrade 3 layers and 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 silicon glass fiber, which improves the thermal insulation effect and is non-slip. 2. 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. 3. 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 rest on the mat. 4. Warm reminder - do not place the heat source directly on the refractory surface, there should be at least 10 cm distance between the fireproof 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. 5. Waterproof and Durable - Our fireproof bowl mats are waterproof and can resist rainwater. At the same time, you can easily remove grease, mud and other stains from the fireplace mat with water and a towel. Materials ensure a long life, allowing you to enjoy the warmth and comfort of a fireplace on your deck.
