Our group
Founded in 1997, Masterplast is the largest Hungarian-owned building materials manufacturer in the Central European region — with production of its own and the stable backing of a listing on the Budapest Stock Exchange. That stability rests on continuous development, a customer-focused outlook and carefully tended partnerships.
Manufacturing and trade
Our vertically integrated manufacturing model makes the entire product portfolio from capacity of our own — from EPS and XPS insulation through roof underlays, nonwoven fleece and fiberglass mesh to glass wool. Production of our own and a focused trading strategy keep the supply chain stable and quality under continuous control.

Our Sárszentmihály site is home to our headquarters, the centre of our domestic and international trade, and our European-quality nonwoven fleece manufacturing.
