"For the interior, we needed a door with an unlined frame as tall as the room height, i.e. from floor to ceiling, over 2.6 m high. There was nothing to discourage us from working together; on the contrary, we were looking forward to it. We really liked the meeting with Mr. Colon in the JAP showroom. His technical erudition and the products themselves. We got a quality door with a clean design and were surprised by the excellent acoustic properties."
