Why James Hardie HardiePlank® Works For Trade & Commercial Projects
Timber can move, split, rot, and need regular treatment. HardiePlank fibre cement cladding gives a similar painted wood appearance, but with far less maintenance over its service life. For contractors, this means fewer call-backs. For property owners, it means less repainting, fewer repairs, and a cleaner facade for longer.
A2-s1,d0 Fire Rated Exterior Board
HardiePlank cladding achieves an A2-s1,d0 fire classification.
This gives specifiers, developers, and installers a non-combustible cladding option for projects where safer external wall materials are a key part of the brief.
Cedar Woodgrain Finish
The cedar finish gives HardiePlank boards a natural timber texture without using softwood cladding.
It works well on residential facades, garden buildings, schools, offices, retail units, hospitality spaces, and mixed-use schemes where a warmer exterior finish is needed.
ColourPlus™ Factory Finish
The pre painted HardiePlank surface uses ColourPlus™ technology for stronger UV resistance and colour retention.
The finish helps reduce repainting needs, which is useful on commercial properties, rental stock, and large exterior elevations where access costs can be high.
Built For UK Weather
Rain, frost, wind, hail, and moisture exposure can damage weaker exterior boards over time.
James Hardie fibre cement cladding is made to resist swelling, rot, mould, cracking, and pest damage, helping the building envelope stay tidy and stable across changing seasons.
Complete HardiePlank Cladding System
Colour matched aluminium corner trims help create a neat finish on external and internal corners. They’re made for both HardiePlank lap and Hardie VL systems, giving installers a cleaner result across different elevations.
The vented starter profile supports the base of the cladding system, while the top ventilation profile helps manage airflow at the head of the installation. Both are available for 25mm, 38mm, and 50mm depth options.
James Hardie EPDM joint tape protects battens behind board joints. It gives added weather protection and helps create a more durable installation on exposed facades.
Stainless Steel Cladding Screws
The 4.2 x 40mm Torx timber fixings are designed for HardiePlank and Hardie VL Plank installation. Stainless steel construction helps reduce corrosion risk in outdoor use.
HardieSeal Edge Coating
HardieSeal colour matched acrylic paint is used on cut edges and small repairs, helping maintain a consistent finish across boards, trims, and installation details.

Where HardiePlank Cladding Is Used
Housing Developments
HardiePlank siding is a practical choice for developers and housebuilders needing a consistent, low maintenance external board across multiple plots.
Commercial Buildings
Retail units, offices, hospitality venues, schools, and public-facing buildings benefit from a durable fibre cement facade with reduced maintenance demands.
Renovation & Recladding Projects
HardiePlank is often used to replace tired timber, uPVC, or older cladding systems. It gives a cleaner exterior finish with stronger resistance to weather and wear.
Garden Rooms & Outbuildings
