| | | Willstrong* is a composite panel consisting of two aluminium cover sheets of Peraluman alloy-100(AIMg1) EN AW-5005 A according to EN 485-2 and a plastic or high mineral filled core. Willstrong* is produced with various core thickness in a continuous lamination process. All painted panels are supplied with a protective peel-off foil. | | |

| | | Rear ventilated Willstrong* architectural cladding considerably improves sound insulation furniture. For example, the sound insulation of a light-weight concrete wall is double when clad with Willstrong". The loss factor (a measure of the acoustic sound-damping behaviour) of Willstrong0 is approx. 6 times better than that of solid aluminium sheets. | | |

| | | |
| | | The composite structure of Willstrong* ,two aluminium cover sheets and a plastic or mineral filled core.results in an impressive strength-to-weight ratio, even when comparing large panel sizes. Despite its low weight, which makes Willstrong* easy to transport and handle in the factory and on site, its rigidity and high strength make it the most suitable material for exterior wall cladding. As long as properly designed and installed, Willstrong* panels will keep their shape and remain flat for life, even when exposed to extreme temperature changes. | | |
