Most fire pit, generate temperatures of at least 1000 degrees F while the surface of composite decks starts degrading and even melting at temperatures of from 250 degrees F. So for this reason, is absolutely necessary to shield your floor surfaces, composite decks and grass from the extreme temperatures generated by fire pits by use of a deck protector. This way you will enjoy the warmth from your fire pit without having to worry about extreme temperatures ruining your precious deck.
Deck protectors work by effectively deflecting heat and are made from a variety of materials that can withstand temperatures of up to 1400 degrees F.
So how do deck protectors work as fire pit heat shields?
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.
