Ulltraclad® Vertical Weatherboard Cavity System


The Ulltraclad® Vertical Weatherboard Cavity System is a cavity-based, interlocking powder coated aluminium weatherboard system. It is designed to be used as an external wall cladding system for residential and light commercial type buildings where domestic construction techniques are used.

The system includes vertically fixed Ulltraclad® weatherboards, cavity battens, internal and external corner mouldings, starter strips, board jointers, board locators, joinery flashings and accessories.

The system incorporates a primary and secondary means of weather resistance (first and second line of defence) against water penetration by separating the cladding from the external wall framing with a nominal 20 mm cavity.
