The intention was to have only a PVC floor installed. Since it is a house from the 70s' with wooden floor on recommendation further looked. Finally ended up at Compofloor. During my conversation with Perry I immediately felt good about it. The renovation floor could be installed very quickly. Paul and Appie have done this job (26 m2) within 5 hours. This is now flat and airtight. The wiring of the floor heating has also been taken into account during assembly work. Thank you men.
