EXTHA, created in 1984, is a group which is specialised passive fire protection. We are designers, manufacturers and appliers of firewall products that are used in buildings, tunnels and refineries. Our market knowledge, our professionalism and the establishment of several EXTHA agencies all over the French territory, have enabled our company to become leader in terms of installation of fire resistant ducting, with one of the widest range of products in the current market.

Our technical solutions have been chosen to equip large private and public projects in France and abroad.

Thanks to our early research and development policy, we have a range of products tested and approved by the European legislation.
