Concealed sash window
The option “Concealed Sash” in the aluminium window System WICLINE evo features a special glazing bead fixed directly in the thermal break zone. As a result the system achieves an extremely slim frame elevation, superior thermal insulation values and a groove-free profile design from outside. The improved ratio between frame and glazing surfaces leads to very good Uw-values, increased light transmissions and panoramic views.
