Some fire pits will cause only minor damage to composite or wood decking, and some will cause major damage depending upon the type of fire pit and various factors such as weather, type of fire, etc. There are several solutions available online for protecting your deck from the heat that can radiate from a fire pit. Some are bad idea and will simply not do the job. Some will protect your deck under some fire pits and some conditions. DeckProtect was designed by thermal engineers to protect any type of decking under any type of fire pit.
How DeckProtect Works
Two layers of tiles made from basalt fiber are set in a study aluminum frame. Basalt is the technical term for a type of volcanic rock. The basalt is melted at extremely high temperature and then formed into a filament fiber. The basalt fiber is pressed into a board that is 3/8″ thick. The board is then cut into tiles to fit snugly in two layers in the aluminum frame. Before inserting the tiles, the frame is powder coated with one of our four colors: polished aluminum, black, copper, or dark bronze (shown above). In addition to being an effective insulation material, the basalt board is fire-proof. Hard rubber feet raise the frame a half inch above the deck to provide air flow. That air space not only keeps the frame above the deck, it also keeps the deck from trapping moisture, staining, or developing mold or mildew. No other system provides the same total protection for any type of decking.
