Gypsum industry news

US: Saint-Gobain subsidiary CertainTeed Interior Products Group has successfully doubled the production capacity of its Palatka, Florida, gypsum wallboard plant. The producer says that the expansion has created 110 new jobs at the plant and made it the largest in the world. The project received US$7m in total funding and tax credits from state and county governments.

President and CEO Mark Rayfield called the Palatka plant ‘A vital part of our operations.’

Canada: Saint-Gobain Canada has scaled up its Kootenay West, British Columbia, gypsum mine to full production capacity of 400,000t/yr. The mine supplies gypsum wallboard subsidiary CertainTeed Canada's Calgary and Vancouver plants. It has an anticipated operational lifespan of 40 years and employs 30 people. The mine will replace the role of the Windermere gypsum mine in Saint-Gobain Canada’s gypsum wallboard operations. The Windermere mine will continue to operate for another 15 years, supplying customers in the agriculture and cement sectors. The company first broke ground on the new mine at Kootenay West in 2019.

CertainTeed Canada has initiated permitting for the construction of a rail loadout at the Kootenay West mine. When commissioned, the facility will reduce the total annual distance of gypsum transported between Kootenay West and the company’s gypsum wallboard plants by 94% from 4.5 million kilometres to 250,000km.

CEO Jean-Claude Lasserre said "It is with great pride that we officially launch full operations of our Kootenay West gypsum mine in British Columbia, a strategic expansion of our presence in Canada, strengthening our operations to continue meeting the construction market demand.”

US: Saint-Gobain North America has launched a new programme of partnerships with high schools in US host communities called Sustaining Futures, Raising Communities. The producer will supply partner schools with a curriculum of classes on manufacturing, with accompanying visits to its plants.

The launch follows earlier pilots at schools in Granville, North Carolina, and Shakopee, Minnesota. It will expand to include 10 additional sites in the 2025 – 2026 school year, followed by further planned expansions throughout the US and Canada.

Saint-Gobain North America and CertainTeed President and CEO Mark Rayfield said "Our Sustaining Futures, Raising Communities programme is a win-win for students, the manufacturing industry and local economies. In the manufacturing industry anyone can have a long and successful career, and by bringing manufacturing directly to high schools, we aim to show students the rewarding role they can play in building the future of the industry."

Canada: France-based Saint-Gobain has inaugurated its CertainTeed gypsum wallboard plant in Sainte-Catherine, near Montreal. The unit is fully electrified and powered by hydroelectricity. The company says that the site is the first zero-carbon (scope 1 and 2) wallboard plant in North America and the largest in the world to be fully powered by electricity. The launch of a new production line at the existing plant, along with equipment modernisation, has enabled a 40% increase in production capacity while reducing energy consumption by 30% and CO₂ emissions by approximately 44,000t/yr.

Mark Rayfield, CEO Saint-Gobain North America said “This ambitious project strengthens our leadership position in light construction in Canada and meets the strong local demand for sustainable solutions. It accelerates our growth in the country, where we have tripled in size in three years.”

The upgraded wallboard plant is the group’s second after the one in Fredrikstad, Norway that was inaugurated in 2023.

Canada: Saint-Gobain subsidiary CertainTeed has concluded a year-long trial to increase the efficiency of CertainTeed 5/8 Type X gypsum wallboard production at its Winnipeg plant through recipe optimisation and technology upgrades. The producer adjusted its water-to-stucco ratio and replaced the line’s existing magnetic flow meters with Coriolis flow meters. It cut water usage by 1.09 million litres (3%), energy consumption by 25,000MWhr and CO₂ emissions by 5.6t year-on-year, while also increasing productivity by 5% year-on-year.

The producer now plans to roll out other water management initiatives based on the case study of the Winnipeg plant across its plants in Calgary, Montreal, Toronto and Vancouver.

US: The Gypsum Association has appointed Christian Chinsio as its new Director of Codes, Standards and Research. Chinsio has 28 years’ experience in management and technical roles in the building materials industry. He is Technical Development Manager at CertainTeed Gypsum, with responsibility over product rationalisation, competitive testing and quality improvements across plants nationwide. He previously represented CertainTeed Gypsum on the Gypsum Association's Building Code and Technical Committee. Other prior management roles include positions at Continental Building Products and Lafarge North America.

Gypsum Association Executive Director Steve Meima said "Christian's 28 years of building products manufacturing experience, the past 25 being specific to gypsum panel and gypsum products manufacturing, is sure to serve well the interests of our members and the technical information needs of architectural, engineering and construction professionals."

US: Workers have walked out of Saint-Gobain CertainTeed’s Blue Diamond gypsum plant in Nevada after rejecting the company's final contract offer. The International Brotherhood of Teamsters has reported that 70 of the plant’s employees will participate in the action in protest against the contract offer, which fell ‘way short of acceptable.’

North America: Saint-Gobain North America has won a Silver Stevie Award in the Large Manufacturing Company of the Year category for its circularity initiatives, rapid growth and commitment to US industrial development. 3BL News has reported that the company will claim the prize at the 23rd annual American Business Awards ceremony in New York City later in 2025.

The recognition comes as Saint-Gobain celebrates its 360-year anniversary. It has invested a combined US$400m in plant expansions and upgrades scheduled to come online in 2025, including building North America’s first carbon-neutral gypsum wallboard plant at its Montreal facility in Quebec, Canada.

Canada: CertainTeed Canada will begin to sell its new CarbonLow range of reduced-CO₂ gypsum wallboard in 2025. The range includes Easi-Lite, Type X and M2Tech boards and GlasRoc sheathing. The products offer 60% lower emissions cradle-to-gate than the company’s ‘traditional’ gypsum wallboard.

Canada: CertainTeed Canada has received environmental assessment approval from the Nova Scotia Department of Environment and Climate Change for its Antrim Gypsum Project in Halifax County, Nova Scotia. It can now move to the project’s permitting phase and toward construction beginning in 2026.

The subsidiary of France-based Saint-Gobain intends to establish operations in Nova Scotia, where eastern North America’s only known major source of gypsum is located. The company will then strengthen its ability to supply its wallboard plants in eastern Canada and the US with locally mined gypsum.

CertainTeed Canada also recently completed construction on its Kootenay West Mine in British Columbia, which is now operational at full capacity with plans to develop a new railway to connect better to other units in western Canada. The company is also reopening its Amaranth Mine in Manitoba to serve central Canada. These efforts are in addition to a partnership with New West Gypsum to recycle and reuse wallboard in production in Alberta, British Columbia, Manitoba, Ontario and Quebec, which has led to over 1Mt of wallboard being recycled and reused at the Vancouver plant alone.
