Projoint NAN is a natural aluminium expansion joint with an interchangeable elastic vinyl resin insert, available in either grey or stone grey. The special structure of the Projoint NAN joint allows it to protect the edge of the tile and at the same time withstand a high volume of traffic, both pedestrian and vehicular. The strength and shock-absorbing capacity make this expansion joint perfect for use in working and industrial environments. The perforated flanges ensure perfect anchoring between the previously split screed, the profile and the tiles.
