Fire Resistance

Tridipanel has the following fire-resistance ratings, (Ratings are valid for fire exposure from either side) Fire-rating is derived from the wire mesh gauge in combination with concrete thickness. See chart below. The insulation core Type I polystyrene foam 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 does not contain ozone-damaging chlorofluorocarbons (CFC's) in the manufacturing process or products. 2.5" EXP-Core with 1.50" Shotcrete each side = 1.5 Hours 2.5" EXP-Core with 2.00" Shotcrete each side = 2.0 Hours 2.5" EXP-Core with 3.1/8" Shotcrete each side = 4.0 Hours The fire rating increases with greater quantities of cement applied to each side. Polystyrene core will not burn.
