The Jenkin A-lign® Bevelback Weatherboard Cavity Cladding Solution is a cavity-based external wall cladding solution for residential and light commercial type buildings where domestic construction techniques are used. The solution consists of horizontally fixed Jenkin A-lign® bevelback timber weatherboards installed over Jenkin A-lign® timber battens to form the cavity, flashings and accessories and is finished with two coats of 100% premium acrylic house paint. The solution 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 frame with a nominal 20 mm drained cavity.
