Linea™ Weatherboard is a 16mm bevelback fibre cement weatherboard, which is designed to be used as part of an external cladding system for residential and light commercial type buildings where domestic construction techniques are used.
Linea™ Direct Fixed Weatherboard Cladding consists of Linea™ Weatherboards applied direct to the external wall framing over a flexible underlay. Linea™ Weatherboard Cavity Cladding consists of Linea™ Weatherboards fixed over timber battens to form the cavity. Both cladding methods (referenced as the system) incorporate secondary protection behind all internal and external corners, flashings for windows, door and meter box penetrations as well as air seals to all wall penetrations.
Linea™ Weatherboard Cladding is finished with a latex paint system.
