Scranton, private equity and a family of building brands.

AZEK began as a product brand inside a Pennsylvania building-materials group before it gave its name to the group itself. For most of its history the parent company was CPG International, headquartered in Scranton, Pennsylvania. A CPG International release announcing a deal for TimberTech in 2012 described the company as the parent of AZEK Building Products and as a maker of low-maintenance building products designed to replace wood, metal and other traditional materials in residential, commercial and industrial construction.

The same release lists the brands CPG then sold: AZEK Trim and Moulding, AZEK Deck and AZEK Rail, alongside commercial and industrial names such as Santana Products, Comtec Industries, Capitol, TuffTec, Hiny Hider and Celtec. AZEK was the brand homeowners and builders saw on exterior trim, decking, railing and porch boards; the other names served schools, offices and industrial buyers.

Ownership in this period ran through private equity. PE Professional reported in August 2013 that AEA Investors had first invested in the company in May 2005, and that CPG was still majority owned by AEA when it agreed a new sale. On 19 August 2013 CPG International announced a definitive agreement to be acquired by funds managed by Ares Management and the Ontario Teachers’ Pension Plan. The Ontario Teachers’ release said Ares and Teachers’ would hold equal economic interests, with senior management keeping a minority stake, and named the brands under which CPG sold its products as AZEK, TimberTech, VYCOM and Scranton Products.

By then the business had added the decking name that would sit beside AZEK for the next decade. In the 2012 release CPG announced a definitive agreement to acquire TimberTech, then a subsidiary of the Crane Group, a family-owned company founded by Robert S. Crane Sr. in 1947. Chief executive Eric K. Jungbluth said that “the ultimate goal is for our AZEK business and TimberTech to join forces.”

A rename, a listing and a new owner.

The TimberTech deal had a family history behind it. In the 2012 release Mike Crane, president of The Crane Group Companies, said the Crane Group had once held a majority interest in CPG, and described the sale as keeping TimberTech “in the family.” Tanny Crane, president of the Crane Group, called it a difficult decision for the company and the family. Jungbluth described the deal as “a merger of equals,” saying that AZEK had led the conversion from wood exterior trim and decking to cellular PVC while TimberTech had been a force in composite decking.

The product name moved up to the company in 2018. Building Products Digest reported on 31 January 2018 that CPG International LLC, then based in Skokie, Illinois, had renamed itself The AZEK Company, reflecting the growth of its deck and railing division. The report quoted chief executive Jesse Singh, who said the company would keep engineering premium building products and acquiring new offerings “that envelop the house.”

Two years later the renamed company went public. A release datelined Chicago on 11 June 2020 announced that The AZEK Company Inc., formerly CPG Newco LLC, had priced its initial public offering, with its shares expected to begin trading on the New York Stock Exchange on 12 June 2020 under the ticker symbol AZEK. The ticker and the company name now matched the brand on the boards.

The portfolio was reshaped again in 2025. PE Professional reported in June 2025 that Sky Island Capital had acquired Scranton Products, the maker of plastic bathroom partitions and lockers, from The AZEK Company; the report traces that business to Santana Products, founded in 1978. Then, on 1 July 2025, James Hardie announced from Sydney and Chicago that it had completed its acquisition of The AZEK Company, and that AZEK stock had ceased trading on the NYSE. James Hardie listed its exterior brands as Hardie, TimberTech, AZEK Exteriors, Versatex, StruXure, Ultralox and Intex, and named Jon Skelly president of AZEK Residential and Sam Toole chief marketing officer for AZEK brands.

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.

One brand, several jobs.

The most interesting thing about AZEK’s identity is how many jobs the one word has done. In the 2012 TimberTech release it is a product family, written with a registered mark and paired with a plain descriptor: AZEK Trim and Moulding, AZEK Deck, AZEK Rail. It also named a business unit, AZEK Building Products, that sat under a parent with a different name.

In 2018 the word became the company. CPG International, a name built from initials, gave way to The AZEK Company, and the brand that customers had seen on trim and decking now stood over the whole group, including its TimberTech decking and its commercial lines. Building Products Digest tied the change to the growth of the deck and railing division, so the new name pointed to the part of the business closest to the homeowner.

In 2020 the word did a third job, as a stock ticker. The IPO release set out the new legal name, The AZEK Company Inc., and the ticker AZEK on the New York Stock Exchange, so investors, contractors and homeowners now met the same four letters.

After 2025 the arrangement shifted again. Inside James Hardie, AZEK sits within a family of exterior brands, and the acquisition release uses it in several forms: AZEK Exteriors as a product brand alongside Hardie and TimberTech, AZEK Residential as a business with its own president, and “AZEK brands” as the portfolio overseen by a dedicated chief marketing officer. The name that once climbed from a trim board to a company has moved back into a portfolio, while keeping its own leadership.

The word is set in capitals by the companies that have owned it, and James Hardie’s 2025 release keeps that form.

For a design guide, AZEK shows how a product brand can be promoted to a company name, take on a stock ticker and then return to a portfolio without losing its identity. Compare it with TimberTech, its decking sibling since 2012, and James Hardie, its owner since 2025. For this guide we use slate navy, driftwood and trim white with a sans, an unofficial interpretation; no product or logo is reproduced.
