JELMO®-Train is a light okoumé-plywood especially developed for railcar building, whose fire-resistance is achieved through the impregnation of the veneer with special salts. JELMO®-Train guarantees a burnback time of 30 minutes according pre EN 45545 and therefore fulfills the bulkhead function. In the JELMO®-Train light version ceiba-wood is used, thus making it possible to save up to 45% weight in comparison to conventional plywoods.

JELMO®-SHIP is a light oukumé-plywood especially developed, whose fire-resistance is achieved through the impregnation of the veneer with special salts. In the JELMO®-Train light version Ceiba-wood is used, thus making it possible to save up to 45% weight in comparison to standard plywood. JELMO®-SHIP is the first plywood with the “steering wheel certification” which was issued by Germanischer Lloyd. In practice, JELMO®-SHIP has proven itself remarkably as a flooring element, wall or ceiling paneling, partition wall, for built-in cabinets and furniture as well as upholstery.
