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.
