HardieWindbreaker™ sheathing board is a non combustible, next generation weather defence air barrier by James Hardie.
With superior fire resistance, water-tightness and breathability, HardieWindbreaker sheathing helps new builds 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 weatherproof ventilated rainscreen cladding system. It can used as part of either steel or timber frame structure.
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.
fermacell® Powerpanel H₂O
A cement-bonded lightweight concrete construction board with a laminated structure, reinforced on both sides with an alkali-resistant glass fibre mesh. It offers many advantages for wall and ceiling constructions exposed to high levels of moisture.
The Powerpanel H2O is also suitable as an external render board application.
When cutting fermacell® Powerpanel H2O boards, no harmful dust is released. Special safety measures are not required.
The visible surface of the panel consists of a formwork-smooth exposed concrete surface, the reverse side is slightly undulated or sanded for calibration and they are cement grey in colour.
In addition to fermacell® products for exterior walls and ventilated facades, James Hardie also offers fade and weather-resistant cladding for long lasting beauty made of fibre cement.
James Hardie fibre cement is thinner and lighter-weight, yet stronger and easier to handle than most alternative building materials, ensuring your build moves along faster - with less hold ups and complications.
