Classic Porthos encloses all the tradition of a solid wood door with frames and rusticated panels. Classic series’ claddings are realized through the use of solid wood frames, transoms and rusticated panels made of water-repellent, multi-layer wood veneer. The paneling has a total thickness of 20 mm and it is applied to the sash with a mechanical anchorage screwed onto a 15/10 steel plate. Classic series can be realized on the external side only.
