Fire Ratings For EVG 3D Panel System
Fire-rating is derived from the wire mesh gauge in combination with cement thickness (see chart below). The insulation core Type I polystyrene demonstrated a flame spread index of 25 or less and a smoke developed rating of 450 or less when tested in accordance with ASTM-E84. The modified polystyrene core will not burn and does not contain ozone-damaging chlorofluorocarbons (CFC’s) in the manufacturing process of products.

• 2.5″ polystyrene core with 1.50″ cement each side = 1.5 Hours
• 2.5″ polystyrene core with 2.00″ cement each side = 2.0.Hours
• 2.5″ polystyrene core with 3.1/8″ cement each side = 4.0 Hours

The fire rating increases with greater quantities of cement applied to each side. The polystyrene core will not burn.
