I-Series™ innovatively combines Infinity™ decking technology with the I-beam shape, to create the strongest, most durable semi-solid composite board available. This design significantly reduces the risk of profile bending. The stress profile is triangular and near zero at the neutral axis, increasing load capacity. The open sub-surface design promotes ventilation and prevents moisture build up, avoiding the moisture-related issues facing older hollow models. It also reduces surface heat retention by encouraging air flow and ventilation. I-Series™ boards can span up to 600 mm centre to centre, an unprecedented feat until now. It’s lighter weight, easier to transport to and on site, and requires less substructure material and fasteners than traditional timber or composite profiles. To top it all off, I-Series™ production has nearly zero waste, making this new composite as eco-friendly as it is consumer-friendly.
