Projoint DIL NL is a coextruded PVC movement joint. Made of nontoxic, shockproof and UV-resistant material, this unique movement joint has perforated flanges to ensure perfect anchoring between the substrate, mortar and tiles. Projoint DIL NL is ideal for tiles or marble from 5/16" to 3/4" (8 to 20 mm) and, thanks to its elastic core, can absorb all traction and compression stress. This characteristic makes the profile especially suitable for surfaces subject to pedestrian or light vehicle traffic (cars and forklifts), both inside and outside.
