Gyproc – Building Ireland’s Future Since 1936
Gyproc is Ireland’s leading manufacturer of plaster, plasterboard, and drylining systems, proudly serving the Irish construction industry for nearly a century. Our story began in 1936, when Gypsum Industries was founded in Kingscourt, Co. Cavan, marking the start of local plaster manufacturing in Ireland.
A Legacy of Innovation and Leadership
From our early days milling gypsum in the 1930s to the opening of Ireland’s first plasterboard plant in 1947, Gyproc has consistently led the way in construction innovation. Over the decades, we’ve expanded our operations, opened new mines, and invested in cutting-edge facilities to meet the evolving needs of Irish builders and homeowners.
In 2005, Gyproc became part of the Saint-Gobain Group, a global leader in sustainable building solutions. This partnership has strengthened our commitment to delivering high-performance, environmentally responsible products.
