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
condensation.
· 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.
