PROSOL 30-35-40 are self-adhesive or punched joint - covers in polished brass available in various widths. They are used to join floors of the same or differing material and thickness. The rounded shape also allows the profile to be used to edge shallow floors max. 5 mm thick. PROSOL is normally used to cover flaws and defects created during laying of ceramic/wood/parquet floors by covering the joint/threshold. PROSOL is recommended for all sorts of public environments: hotels, offices, shops and private dwellings; it guarantees an impeccable and attractive finish.
