External Sheathing

With superior fire resistance, water-tightness and structural racking strength, HardieWindbreaker™ sheathing helps new builds stand the test of time.

• A quicker build: early close-in avoids weather delays, removing the need to reschedule trades and reducing unplanned equipment hire costs. Our boards will not warp or shrink when exposed to adverse climates and offer a guaranteed 12 months exposure during construction.
• A simpler build: offers a complete solution for external wall racking strength and structural connectivity. Lightweight, easy to cut, flexible to handle and fix.
• A more weather-tight building: provides superior weather-tightness as our water-repellent sealant stops moisture getting in; the board’s breathability allows moisture vapour to get out.
• A stronger building: made from engineered fibre cement, adding strength to your building.
• A quieter building: better soundproofing helps to absorb unwanted noise.
• Made for extra high wind zones: our boards help to equalise the air pressure inside the outer wall cavity, allowing your building to stand up to extra high wind zones.
• Guaranteed & tested for peace of mind: made from advanced material fibre cement, the boards won’t crack, warp, swell or rot, and come with a full 15-year James Hardie warranty.
