Projoint DIL NZS is a technical movement joint designed to protect the corner of tiles and easily withstand pedestrian and vehicle traffic. With its two parts joined telescopically with special articulated flanges, Projoint NZS allows movements of up to 3/16" (5 mm) in three dimensions. This is an especially useful function for commercial environments and industrial contexts. Specifically, Projoint DIL NZS/A/40 is the cover version, offering the same features but for installation over existing floors.
