Features of Duct-Automatic

Chemical resistance of rigid polyurethane foam (PUR/PIR)

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.
