Forest based composites for façades and interior partitions to improve indoor air quality in new builds and restoration


Conenor history goes back to late 1980’s when a Finnish inventor Kari Kirjavainen made one of his technical inventions; the conical extruder, an entirely new and different rotory extrusion technology to extend the limits of conventional screw extruders.

In 1995 he started company Conenor Ltd together with Uponor Group for managing the industrial developments of CONEX with help of Maillefer Extrusions in two parallel Tekes co-financed projects, one for pipe application and the other for cable coating, at the premises of VTT at the city of Tampere.  He is nowadays retired from the company operations.

Besides of CONEX, a plastic film orientation technique and unique transverse direction stretcher (TDO) named TRIAXCELLhave been invented and developed by Conenor. The company has divested this technology and focused since exclusively in extruded composites.
