Projoint DIL NL is a co-extruded PVC expansion joint. The product - made of non-toxic, shockproof and UV-resistant material - features perforated side flanges for perfect anchorage between the (previously split) screed, profile and tiles. NL is ideal for adhesive-laid floors or marble between 8 and 20 millimetres thick and, thanks to its elastic central part, is able to absorb compression and expansion stresses. This characteristic makes the profile particularly suitable for surfaces with light pedestrian or vehicle traffic (cars and pallet trucks) indoors or outdoors.
