Projoint DIL NZS technical expansion joint is designed to protect the tile edge and easily withstand pedestrian and vehicle traffic. Thanks to its two parts, joined telescopically with special articulated fins, Projoint DIL NZS allows three-dimensional movement, tolerating movements of up to 5 millimetres. A very useful feature especially for workplaces and industrial settings. In particular, Projoint DIL NZS/A/40 model is the joint-covering version, with the same features, but intended for installation on already-existing flooring.
