Deck protectors work by balancing elements that relate to heat transfer and heat insulation. For heat transfer, some fire pit defenders come with a shiny metal such as powder coated steel frame or aluminum that will reflect the heat. For insulation, multilayered metals with air spaces or volcanic rock fiber effectively act as a blockage.
Have you ever left your deck protector on your deck for some time and after a while started noticing stains on your deck? Well, some deck protectors come with drilled with holes on the frame for drainage and to keep moisture from accumulating. They also feature legs  to keep the frame off of the deck which will allow air to flow between the deck and the frame for better cooling of the deck and also ensure no mildew or stains form on the deck.
