WICLINE 75 TOP hidden sash

In the concealed sash type of the WICLINE 75 TOP aluminium window system,

the glass is fixed directly to the insulated area by means of special glass strips.
This allows the visible sash to be very narrow in size,

resulting in good insulation values and no overlap of the outer sash.
