Its many attributes include:

  • · Highest R-value per inch of thickness
  • · Moisture resistant, water repellent panel
  • · Resistant to solvents used in construction adhesives
  • · Excellent dimensional stability
  • · Surface temperature range from -40 °C to +80 °C
  • · Long Term R-value (only roof insulation with third party certification)
  • · Recycled content
  • · Zero ozone depletion potential
  • · Virtually no global warming potential
  • · Nationwide availability
  • · PIR (Polyisocyanurate) foam has the highest insulation capacity of all known insulation materials (i.e. polystyrene, glass wools, etc.)
  • · The material is totally harmless to humans and environment.
  • · The application is quick and easy. The material can be cut easily to any size.
  • · It has good resistant against shocks and beats up to 10 t/m2.
  • · The insulation can be installed in any weather.
  • · Low moisture pick-up: (0.32% after emersion in water for 96 hrs).
  • · Total Protection of the waterproof membrane from temperature extremes, UV radiation, mechanical damage and damage due to interstitial
  • · Maintains roof structure temperature close to that of internal temperature of the building.
  • · PIR Foam is resistant to weak acids and alkalis, oils and fats and petrol.
  • · The PIR foam sticks to almost all materials such as wood, stone, brick, aluminum and plastic; all surfaces no matter how large or small or difficult to
       reach; horizontal, vertical, or diagonal.
