Two layers of fibrous board made from flame-proof basalt, which is a volcanic rock, block and disperse the heat. No matter how hot it gets under your fire pit, the temperature under the DeckProtect will not reach a level that could harm your deck or patio.

The frame holding the basalt board is made from heavy-duty aluminum which is completely weather-proof.

Hard rubber feet raise the frame above the surface to allow for air flow and ensure that your deck or patio will not become stained from trapped moisture.
