A Scottish tanner’s son, an agency and a sample of slate.

James Hardie is a building-materials group best known for fibre cement siding and cladding. Its story starts not in building but in leather. The Australian Dictionary of Biography, in an entry by John Lack published in 2005, says that James (Jim) Hardie was born in Linlithgow, Scotland, the son of a master tanner, and learned the trade in his father’s firm before leaving for Australia. He arrived in Melbourne early in 1887 and set up an office importing and supplying machinery and chemicals to the city’s tanneries. The company itself counts its history from 1888: its centenary history, written by B. Carroll, is titled ‘A Very Good Business’: One Hundred Years of James Hardie Industries Limited 1888–1988.

The Australian Dictionary of Biography describes a careful, well-connected trader. Hardie served as honorary secretary of the master tanners’ association of Victoria, which met in his Flinders Lane office, and in 1892 he recruited Andrew Reid, a Linlithgow acquaintance, as his salesman. Reid became a junior partner in 1896, owned a half share from 1899 and set up the firm’s Sydney office in 1900. In 1902 the business was described as importers, shippers, and leather and bark factors.

The turn towards building came from a trip abroad. According to the same entry, Hardie toured Britain, Europe and North America in 1903 and came back with new agencies and with a trial shipment of a new roofing and lining slate made by the French Fibro-Ciment company. The sheeting, made from cement and asbestos, proved popular, and Hardie & Co. soon became its agent for Australasia and the Pacific. Among its early Melbourne customers was the Victorian Railways, which used the sheeting for linesmen’s huts and for the roof of the new Spencer Street station.

Hardie sold his interest in the firm to Reid in 1912. Reid began Australian manufacture of a sheeting called Fibrolite in 1917 and, when he floated a public company in 1920, kept the founder’s name. After Reid, his sons Andrew Thyne Reid and (Sir) John Reid ran the business.

Listing, relocation and a new set of brands.

English Wikipedia, citing a report in Sydney’s The Sun of June 1952, says the company was listed on the Sydney Stock Exchange in 1951. Through the middle of the century it made asbestos-cement sheet and related building products; citing Gideon Haigh’s 2006 book Asbestos House, Wikipedia says James Hardie ceased all asbestos manufacturing in March 1987. The same article, citing the company’s archived investor history, says it had developed an asbestos-free fibre cement technology in the mid-1980s, and it describes fibre cement as a material made largely of Portland cement, sand and wood fibres.

The corporate address has moved twice. English Wikipedia, citing the company’s own record of its 2001 corporate restructure, says James Hardie relocated its headquarters to the Netherlands in December 2001; citing the Irish Independent of June 2009, it says the company moved its corporate domicile to Ireland in 2010. James Hardie Industries plc describes itself as a limited liability company incorporated in Ireland with its registered office in Dublin, and Wikipedia, citing the company’s careers site, places its management in a corporate office in Chicago. Its shares trade in Sydney and New York under the symbol JHX.

The biggest change to its brand family came in 2025. In a release dated 1 July 2025, James Hardie announced that it had completed its acquisition of The AZEK Company, the American maker of composite and PVC decking, railing and trim. The release said the combined portfolio included Hardie, TimberTech, AZEK Exteriors, Versatex, StruXure, Ultralox and Intex, and that Aaron Erter and Rachel Wilson would continue as chief executive and chief financial officer. Its company description in the same release adds fermacell, a fibre gypsum brand sold in Europe, and says the portfolio is marketed across North America, Europe and the Asia-Pacific region. The same release recorded that the company’s American Depositary Share programme had ended on 1 July 2025 and that its ordinary shares now traded directly on the New York Stock Exchange.

Where the products are made is described only broadly in the sources: English Wikipedia, citing the company’s careers site, says James Hardie operates more than a dozen manufacturing plants around the world, alongside the Chicago office.

Design and documentation.

The brands in this group make the outside of a house: the shingles and membranes on its roof, the boards and panels on its walls and the decking and railings around it. Roofing, siding and decking names sit at many different points in the building trade, from businesses that grew out of a single product or family firm to names that now belong to much larger groups selling a whole range of exterior materials.

Most homeowners meet these brands only a few times, and often through someone else: a contractor, a dealer, a sample board or a colour card. A brand’s identity is therefore carried less by a single product than by its name, its product families, its colour ranges and the programmes it runs for the people who install its materials. Ownership can change several times while the name on the bundle stays the same.

Each guide separates what independent sources record from what the company says about itself — its founding, its owners over time, where its products are made and how its names and product lines have changed — and marks plainly what rests only on the company’s own word.

A founder’s name, shortened to a product brand.

On its American website the company talks less about James Hardie the man than about Hardie the product brand. Its product menus are organised by siding type, from plank lap siding and panel siding to Hardie® Artisan® siding, shake and shingle styles and Hardie® Architectural Panel, with trim, soffit and backer board alongside. Colour sits in its own section, with a Statement Collection® of finishes and a reference to ColorPlus® Technology, and homeowners are invited to order colour samples or try a visualiser called Hardie™ Designer.

The company also runs a contractor programme, the James Hardie™ ALLIANCE, which its site promotes to professionals alongside builder and contractor toolkits, a dealer locator and installation guides. Since the AZEK acquisition, the site’s brands page has used the line “Resilient Beauty™” and presents Hardie®, TimberTech® and AZEK® together as “the James Hardie family of brands”, with a gallery of homes that combine siding, decking and railing from the three names. The company’s purpose statement, quoted by Aaron Erter in the July 2025 release, is “Building a Better Future for All™”.

The name has had a public life beyond building sites. English Wikipedia, citing The Canberra Times of March 1988, says James Hardie was the naming-rights sponsor of the Bathurst 500 and 1000 motor race from 1968 until 1987, and that it was shirt sponsor of the Parramatta Eels rugby league club from 1981 until 1995, returning as sponsor in 2025. The State Library of Queensland, in a blog post of April 2021, records that in 1988 the company gave the Australian Library of Art to the library as a bicentennial gift, a collection that became the James Hardie Library of Australian Fine Arts.

The Australian Dictionary of Biography notes that none of Jim Hardie’s children had children of their own, “but his name survived”: Reid kept it when he floated the company in 1920. The family homes in Melbourne, the same entry says, were named Lithgae or Lithca, after Linlithgow.

For a design guide, James Hardie shows how a founder’s surname can be cut down to a product brand and then stretched to cover other companies’ names, from an importer’s office in Melbourne to siding in North America and decking from TimberTech. Compare it with AZEK and TimberTech, the decking and trim brands it has owned since 2025. For this guide we use teal, cedar and cement grey with a sans, an unofficial interpretation; no product or logo is reproduced.
