James Hardie Cladding
Our non-combustible fibre cement sheathing offers a next generation in weather defence air barriers for new build construction. With superior fire resistance, water-tightness and structural racking strength, HardieWindbreaker™ sheathing helps your project stand the test of time.
HardieWindbreaker™ board can be applied to the outer studs, joists, and rafters of a building to strengthen the structure and serve as a base for an exterior ventilated rain screen cladding system. It can used as part of either a steel or timber frame structure.
Our sheathing provides superior weather-tightness as our water-repellent sealant stops moisture getting in; whilst the board’s breathability allows moisture vapour to get out. The boards help to equalise the air pressure inside the outer wall cavity, allowing your building to stand up to extra high wind zones.
With its inherent properties of fire, rot, moisture and water resistance, fibre cement is the perfect material to render a structure weather-tight, enabling internal trades to begin work in a dry, comfortable environment. Our easy to install boards speed up the installation process, meaning buildings can be occupancy-ready in a surprisingly short schedule.
Our boards will not warp or shrink when exposed to adverse climates, and offer a guaranteed 12 months' exposure during construction.
