InsulBase Polyiso Insulation

InsulBase Polyiso Insulation

InsulBase is a rigid-roof insulation panel composed of a closed-cell polyisocyanurate foam core bonded on each side to glass-reinforced felt (GRF). ReadyFlash® Technology is a standard feature of InsulBase Polyiso that allows the contractor to manipulate flash-off times by choosing which side of the insulation board to apply membrane adhesives. ReadyFlash features a dark glass-reinforced felt (GRF) on one side of the insulation board and a light glass-reinforced felt on the other. 

  • Increases surface temperature of the dark facer up to 25ºF above ambient temperature and provides up to 30% faster adhesive flash-off.
  • Decreases surface temperature of the light facer up to 5ºF below ambient temperature.

Features and Benefits

  • InsulBase polyiso insulation provides the highest R-value per inch of commercially available insulation products 
  • Zero ozone-depleting components, HFC- and HCFC-free formulation
  • Approved for direct application to steel decks
