System of profiles
The construction of V70 OPTIMAL BLACK window is based on Veka A-class profiles of highest quality. This window has been made with the usage of a new five-chamber half-flush stile (total width 84mm). 5mm wider than the standard one. This stile enables to apply glass packages of 50mm thick which improves energy-efficiency of the whole window.
Double-chamber joining of the window panes
In V70 OPTIMAL BLACK We applied double-chamber joining of the window panes of thermal insulation parameter U=0,5W/m²K and construction: 4/18ar/4/18ar/4 (whole structure is 48mm thick). This kind of joining enhances thermal-insulation properties of the window in which Uw=0,9 W/m²K*. By choosing this model you will reduce your heating bills.
Between-panes thermal frame
V70 OPTIMAL BLACK window has been equipped with a between-panes thermal frame which lowers the risk of vapour liquefaction outside the room. Its main advantage is the reduction of the parameter Uw o 0,1-0,3 W/m2K which improves energy-efficiency of the entire window. In result, you can reduce your heating bills by 5%. thanks to the wide range of available colours and elegant matt surface this frame gives the window a bit of elegancy and it gives our customers a chance of matching its colour to the colour of the window.
Sub-sill skirting with a gasket
V70 OPTIMAL BLACK is equipped with a sub-sill skirting with a gasket which allows to properly install the outside and inside sill. Thanks to this skirting the window will provide you with even better thermal and acoustic insulation. A special gasket placed in the skirting is an extra protection from rainwater getting inside the room.
Secustik Swing handle
Swing handle has a completely hidden escutcheon plate. Smooth curve and ergonomic shape makes it look very elegant. Thanks to this V70 OPTIMAL BLACK perfectly fits with every interior. The Swing handle is equipped with Secutik mechanism which blocks its turn when trying to move the window fitting from the outside and prevents from burglary.
