V70 OPTIMAL BLACKis the only product on the market that has been equipped with black Roto NTS covered with a black galvanic layer. It makes the window look elegant and makes it a perfect match for almost every interior. This innovative solution is not only aesthetic but also practical. This fitting is galvanized, chromaned and underwent final treatment which makes it more resistant to corrosion.A great supplement to V70 OPTIMAL BLACK window is also a new semi-flush stile and Secustik Swing handles with a completely hidden escutcheon plate, smooth curves and ergonomic shape

V70 OPTIMAL BLACK is not only an aesthetic solution but also one of very good thermal insulation parameters. Thanks to the 5-chamber construction of the window frame and a special 5-chamber semi-flush stile (width 84mm – 5mm wider than a regular semi-flush stile) makes it possible to use sets of glass of up to 50mm thick. In V70 OPTIMAL BLACK we applied 2-chamber comlex glazing of heat transfer coefficient U=0,5W/m²K and construction: 4/18ar/4/18ar/4 (The total thickness of the set - 48 mm). This solution enhances thermal properties of the whole window (heat transfer coefficient Uw=0,9 W/m²K.)
