James Hardie 300mm Smooth PVC HardiePlank™ Jointer

The James Hardie 300mm Smooth PVC HardiePlank Jointer is a fibre cement building board from Builders Warehouse, built for tradies, builders and confident DIYers who need dependable performance on site. A fibre cement building product engineered for strength, moisture resistance and dimensional stability in wet-area and exterior applications. It’s the kind of product that does its job quietly — reliable, consistent, and ready to go straight from the pallet.

A ready to paint, smooth PVC extrusion used to join HardiePlank™ weatherboard cladding. The ideal accessory to conceal board edges at joints, thus allowing for an improved aesthetic finish. Sizing follows standard Australian building trade conventions, so it’s easy to plan quantities against a typical job. In practical terms, that means the James Hardie 300mm Smooth PVC HardiePlank Jointer holds up to real Australian site conditions without the early failures cheaper alternatives can show.

It’s commonly specified for flooring substrate in wet or exterior areas and exterior cladding and eaves lining, where moisture and impact resistant and paint or tile-ready surface matter most. Builders and renovators choose the James Hardie 300mm Smooth PVC HardiePlank Jointer because it’s won’t rot, warp or attract termites, and because it fits straight into standard trade workflows without extra prep or special handling. If you’re pricing a job that includes the James Hardie 300mm Smooth PVC HardiePlank Jointer, it’s worth ordering slightly more than the bare minimum to allow for cuts, waste and any last-minute changes on site.
