Wood-plastic-composites (WPC) represent a new generation of bio-based materials which meanwhile raised the interest if the building industry. So far, decking and cladding is made from it. Investigations of the composite`s performance under wind suction demand an application-oriented approach. By today, façade planners could not satisfyingly estimate a WPC`s structural resistance relative to so far well-established plastics-based cladding. Furthermore, WPC cladding manufacturers hardly provide applicable product attributes which determine a bending rupture or failure of fixations as main consequence of extensive wind suction. This study examined three plastics-based façade product categories with regard to their wind resistance under varying fixation distances. Wind suction was simulated using foil bags which were filled by air pressure at the rear side of the cladding. Panel deformations were measured along the applied pressure. Local failure around a fixation device was investigated by microscopy analysis. It was found that punching of fixations through the panel material was the only occurring failure mode and a panel`s resistance correlated negatively with the applied fixation distance. As far as the investigated product categories were concerned, pure PVC panels showed poor wind resistance followed by WPC and resin-based chipboard cladding. Moreover, microscopy analysis of the rupture pattern revealed that increasing walls thickness und the use of round predrilled wholes instead of long holes could improve a façade`s resistance. As a consequence of the results it can be theorized that the calculation of the fastener’s resistance is the major proof when selection one of the investigated products categories for a building project.
