A specially engineered dual-layer thermal barrier made, from flame-proof volcanic rock (basalt) fiber, blocks transmission of the heat. Temperatures under DeckProtect are comfortably within the safety zone and way below the range that can cause damage to decking. The aluminum tray holds the barrier sections firmly in place.
A half inch of space below the tray allows air flow to keep moisture from accumulating on your deck. This avoids mildew and staining of decking boards.
The tray with heavy gauge 1/16” thick aluminum is built to last indefinitely. The basalt thermal barrier can absorb rainwater that then drains out through a network of holes in the bottom of the tray.
Hard rubber feet keep the aluminum tray 1’2” above the deck and are strong enough to support the weight of your fire pit as well as a stack of hardwood logs.
Fire Pit Heat RadiationThere are several variables affecting the intensity of the heat reaching the surface of your deck, including ambient temperature, size of the fire, duration of the burn, and height of the fire pit. Even whether or not there is a little breeze can affect the temperature under the fire pit. In some cases the damage to your decking may be minimal; in other cases, the damage could be substantial.
The vinyl or polyethylene shell surface of composite decking starts to degrade and melt at temperatures between 250 degrees F and 350 degrees F. It can soften at temperatures as low as 176 degrees Fahrenheit.
