Elevate your builds and create flawless street appeal for years to come with the bold, new vertical cladding solution from James Hardie, Hardie™ Oblique™ Cladding.  With a similar appearance to metal cladding, Hardie™ Oblique™ Cladding is an easy-to-install alternative made from premium fibre cement.  No need for specialist installers, Oblique™ reduces the number of trades on site, saving you time and money.

Hardie™ Oblique™ Cladding is designed to emulate the look of metal cladding

With vertical cladding in hot demand from homeowners, the new Hardie™ Oblique™ Cladding is sure to be a favourite. Delivering a bold, modern look through its wide grooves and angled edges, Oblique™ Cladding is the only Hardie™ exterior cladding product with a slanted groove edge that mixes shadows and highlights to provide interest and depth.

Hardie™ Oblique™ Cladding is available in 200mm and 300mm wide shiplap boards, which can be alternated for a unique design or installed consistently for a traditional look. Similar in appearance to metal cladding, it’s a durable and easy to install premium fibre cement alternative.

To make things even easier, the horizontal Hardie™ Castellated Battens allow ventilation and drainage through the cavity. The 2750mm boards suit common wall heights to help to reduce waste, while the 4200mm lengths give tall walls a continuous look, reducing the need for horizontal joints. The boards are pre-primed and ready to paint.

Hardie™ Oblique™ Cladding is made with Hardie™ premium fibre cement to keep it looking good. It’s also resistant to damage from termites, rot and moisture, and engineered to stand up to coastal and other harsh conditions.

A new, shiplap system

Hardie™ Oblique™ Cladding is a new premium fibre cement cladding system from James Hardie. Unlike other cladding options from their range, Oblique™ is supplied as individual shiplap boards, installed on a castellated batten.

Step by step guide for installing Hardie™ Oblique™ Cladding

Installing Hardie™ Oblique™ Cladding is simple, straightforward and can be done in just four steps. With the help of Hardie’s extensive range of cladding products, customers can rest assured they are getting stylish, durable cladding that’s built to last.

Step 1

Step 1: install the frame, corrosion-resistant flashings and Hardie™ Weather Barrier

Start by installing your frame, ensuring you have a maximum noggin space of 900mm. All noggins must be aligned to provide continuous support to the Hardie™ Castellated Batten. Install the required corrosion-resistant flashings over windows and other openings before installing Hardie™ Weather Barrier.

Step 2

Step 2: fix the Hardie™ PVC Vent Strips before installing the Hardie™ Castellated Battens

Next, install the Hardie™ PVC Vent Strip along the bottom plate. Install Hardie™ Castellated Battens in a vertical orientation on each side of internal and external corners before installing the Hardie™ Castellated Battens over each noggin and top/bottom plated at max. 900mm centres.

Step 3

Step 3: install the Hardie™ Trimline Flashing and Hardie™ Trimline Flashing jointers

The third step is installing the Hardie™ Edge Trim (optional). Install the internal and external corner accessories and the Hardie™ Trimline Flashing followed by Hardie™ Trimline Flashing jointers.

Step 4

Step 4: apply Hardie™ Joint Sealant and fix Hardie™ Oblique™ Cladding to the frame

Finally, apply a continuous bead of Hardie™ Joint Sealant to the underside of the Hardie™ Trimline Flashing and along the corner accessories. Push the first board against the flange and fix to the

frame. Repeat the process for the remaining boards. Paint within three months of installation, or within seven days if located in a coastal area or corrosive environment.
