The three materials turn up on the same sites and do not play the same part. Here is the comparison as we make it when a client hesitates.
| Material | In a damp room | Sound insulation | Maintenance | Deep scratch |
|---|
| WPC | Made for it: leaf and frame do not take up water | Low | None | Permanent: cannot be sanded |
| PVC | Water-resistant | Low | None | Permanent |
| MDF, melamine, CPL, veneer | Wrong choice: the bottom of the leaf swells, the edge banding lifts | Good to very good | Light | Repairable, depending on the finish |
| Solid timber | Moves with humidity: gaps and warping | Very good | Regular | Repairable by sanding |
Between WPC and PVC the difference never shows in a photo: it is density. A PVC leaf is hollow and light; it sounds hollow, marks on impact and holds a lock less well. WPC has a denser composite core, machines cleanly in the workshop for a lock or a ventilation grille, and takes better to a door that gets slammed several times a day.
MDF is not a rival to WPC, it is its complement. In a bedroom or a living room, a solid-core MDF door is clearly quieter and nicer to the touch — that is what we recommend. In a bathroom, it is WPC. On a villa, mixing the two is the rule, not the exception.
