Created from the same glass fiber reinforced concrete as the Cosmopolitan Fire Tables, this protective cover is designed to fit over the Fire Table opening protecting the burner assembly against wind and rain. Glass Fiber Reinforced Concrete (GFRC) is specially formulated using Portland cement, glass fibers, aggregates, and polymers to give a higher strength with a fraction of the weight of pre-cast concrete. GFRC cannot rust like steel and is weather resistant, fire retardant, and impermeable to give years of enjoyment with cast-in color and low maintenance. They also provide additional surface area for the table top when the burner is not in use. Get more use out of your Fire Table with the protective cover.
