All produced rolls are carefully tested through our state of the art laboratory to ensure that each batch produced meets the CE & ISO standards in terms of :

Mechanical Properties:     - Tensile Strength (max)   - Elongation @ Break   - Tearing Strength ( Nail-Shank )   - Resistance To Static Loading   - Resistance To Impact

Thermal Properties:     - Flow Resistance at Elevated Temperature   - Flexibility at Low Temperature   - External Fire Performance   - Reaction To Fire   - Water tightness   - Joints Tensile Strength (Shear)   - Thermal Ageing In Air: Flexibility At low Temperature
