Our hearth rug is thick and heavy, unlike other rugs with sharp corners. Our hearth rug has rounded corners, so it conforms to the floor perfectly and doesn't lift. We designed this hearth rug to protect floors from charcoal splatter during a fireplace. The mat is large enough and well-made for indoor and outdoor use, preventing burns and protecting the environment. The fire-retardant hearth rug is available in multiple sizes and is made with non-slip silicone on both sides. This grips the floor firmly and prevents slipping. Make sure the non-slip is in direct contact with the floor. Both sides of the fire-retardant mat are coated with a non-slip, fire-resistant, and waterproof silicone coating. You can clean the fire floor protector by vacuuming, sweeping, shaking, wiping with a damp towel, or rinsing with a hose. It easily folds or rolls up for convenient storage when not in use. Our fiberglass fire-retardant hearth rug is versatile and provides excellent protection for floors, carpets, patios, garage floors, and decks. It's ideal for use under fireplaces, outdoor grills, fire pits, stoves, and outdoor fireplaces.
