GRENA

GRENA, a.s. is a Czech manufacturing company with a history dating back to 1941, based in Veselí nad Lužnicí in the South Bohemian region. A proud member of JFD Group, alongside JF Dřevovýroba and JAVAB, the company has grown from its early roots in flax processing into a modern, dynamic manufacturer. A new generation of ambitious, forward-thinking leaders joined in the 1990s, and the ideas they brought continue to shape the company’s growth today.

GRENA operates through two divisions, both with strong potential for innovation. The first specializes in fireproof, fire-resistant, non-combustible and insulating vermiculite boards and shaped parts, used in building construction, shipbuilding, fireplace and stove construction, door manufacturing and many other industries, and exported to more than 30 countries worldwide. The second focuses on surface finishing, including laminating, veneering and high-gloss acrylics, and has been producing kitchen doors for 20 years.

Quality and reputation are central to how GRENA works. The company holds ISO 9001:2015 certification, proudly carries the Genuine Czech trademark, and is an active member of the Guild of Stoves of the Czech Republic, the Professional Chamber of Fire Protection and the South Bohemian Chamber of Commerce.
