The 4x8x5/8 D-Blaze Fire Retardant is a type of plywood or sheet material treated with a fire retardant. The "4x8" refers to the dimensions of the sheet (4 feet by 8 feet), and the "5/8" refers to the thickness, which is 5/8 of an inch. D-Blaze is a branded fire retardant treatment that meets building codes and standards for fire protection in construction. This type of material is commonly used in commercial, industrial, and residential construction where fire-rated materials are required by code.
Its fire-retardant properties make it suitable for walls, roofs, and other structural applications where enhanced fire resistance is necessary. It helps to slow down the spread of fire, giving additional time for evacuation and response in case of an emergency.
