Polyureas have excellent resistance to heat distortion and sagging. At the same time, polyurea maintains its flexibility and high impact resistance. Polyurea will out perform most other polymer resins and Vinyl PVC coated decking when exposed to high levels of UV rays over long periods of time. The resulting low smoke and flame spread is due to polyureas molecular structure. When exposed to constant flame for 20-30 seconds, polyurea will self-extinguish. The Polyurea coating makes Versadeck decking a fire resistant aluminum decking product. Polyurea and PVC Vinyl coated steel and aluminum decking are both considered to be Fire Resistant - Polyurea will hold up longer when exposed to UV rays because polyurea contains no solvents and zero VOC's in comparison to vinyl or PVC coated steel or aluminum decking.
