System Onduline HR
Technical Characteristics
 |
WATERPROOF Absolutely waterproof under all climatic conditions. ASTM D1499, ASTM E96 and DIN52103 |
 |
THERMAL CONDUCTIVITY The thermal conductivity value of Onduline HR is l= 0.105 kcal/mh°C ASTM C177-76 and DIN52123 |
|
 |
LIGHT WEIGHT With an overall weight of 4 kg/sqm, it is highly advantageous with regardto easy application and earthquake safety. |
 |

|
 |
RESISTANCE TO UV RAYS No surface deformation takes place under effects of ultraviolet rays. BS2011 |
 |
BIOLOGICAL CHARACTERISTICS Onduline HR sheets do not decompose nor detoriate by adverse effects of any biological factors such as mold or fungi. |
|
 |
BENDING UNDER VERTICAL LOAD Capable of carrying a homogenously distributed load of up to 350 kg per square meter at a 45 cm purlin distance within the maximum deflection tolerance of l/200 ASTM D1502-60 and BS4154 |
 |
CHEMICAL CHARACTERISTICS Various salts, acids and alkalis do not cause any changes in the performance of Onduline HR. |
|
 |
RESISTANCE TO HIGH AND LOW TEMPERATURE No visible changes occur in the material to a temperature range between -35°C to +105 °C. No cracks or scaling actually take place. The change in dimension due to temperature difference of 50°C is less than or equal to 0.1%. DIN52612 |
