The photo on the right is your typical wood framed home burning to the ground. If you look close you can see the wood studs!
The above home was built in Malibu, California with the Tridipanel System including floors, walls, ceilings and roof structure. The owner's previous home at this location was burned to the ground. The solution to this problem was solved by using Tridipanels.
Fire Ratings For Tridipanel
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 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.
