Projoint DIL NL is a coextruded PVC floor expansion joint. Made of non-toxic, shock-proof, and UV-resistant material, this unique product has perforated flanges to ensure perfect anchoring between the concrete substrate (previously laid in sections), the profile, and the tiles. NL is ideal for floor coverings or marble laid with adhesive and thicknesses from 8mm to 20mm, and thanks to the elastic core, it can absorb all traction and compression stress. This characteristic makes the profile especially suitable for surfaces with light foot or vehicle traffic (cars and pallet trucks), both inside and outside.
