The Protebox mat covers 60 by 40 inches and offers high-temperature resistance up to 2000°F thanks to fiberglass with silicone coating on both sides. It effectively contains embers and spills under grills, minimizing deck damage. The design emphasizes easy maintenance: its surface repels oil and can be cleaned with soap and a hose or wiped down.
UBeesize Large Under Grill Mat

The UBeesize mat measures 65” by 48” and features a double-sided silicone coating with fiberglass construction for heat resistance up to 2000°F. It is fireproof, waterproof, and oil-resistant. The mat cleans easily with soap and water, folds for storage, and often includes a storage bag for convenient outdoor use.

The Demiwise mat measures 76 by 48 inches, offering extra-large coverage suitable for large grills and multiple setups. It provides strong protection against spills, grease, and heat.

The mat is designed for durability and easy cleaning, helping to maintain outdoor spaces after grilling.
Buying Guide
Key considerations when selecting a deck protector for grills include size fit, heat tolerance, material composition, and maintenance needs. A larger mat provides more coverage but may be harder to store; ensure the mat fits your grill footprint and any surrounding furniture. Heat resistance matters, especially for charcoal grills and open flames; seek mats rated up to at least 500°F for routine grilling and up to 2000°F for embers and high-heat sessions. Material quality affects durability and cleaning ease—fiberglass with silicone coatings offer strong protection and wipe-clean convenience, while PVC options may be sufficient for light use but less heat tolerant. Non-slip backing minimizes movement on slick surfaces to prevent accidents. Finally, consider storage convenience: some mats fold, roll, or come with carrying bags for easy seasonal use.
For buyers prioritizing maximum coverage, large mats like 76” x 48” or 75” x 40” provide extensive protection for expansive grilling setups or outdoor kitchens. If you grill on wooden decks, look for materials with robust water repellents and stain resistance to maintain deck aesthetics. On the other hand, smaller or mid-sized mats can be ideal for compact patios or grill stations where space is at a premium. Always measure your space and grill footprint before purchase to ensure a snug, effective fit that stays in place during cooking and cleanup.
