ThermoSpan EPS

ThermoSpan EPS is a polystyrene cored insulated panel, consisting of a 0.59mm profiled roofing sheet bonded to an EPS core with a ceiling panel sheet bonded to the underside. ThermoSpan EPS does have fire retardant properties but is not fire rated. ThermoSpan can be used in residential and commercial applications as load bearing and non-load bearing wall and roofing panels.

ThermoSpan panels are available in a limited colour range from the Colorsteel® range of roof colours, and in the following thicknesses (mm): 50, 75, 100,150, 200, 250, 300. 

Key Features
  • Flame Retardant additive to EPS core
  • Long spans
  • NZ manufactured — longer sheet lengths
  • Thermally efficient
