Hybrid window

The double façade as a coupled window structure

Do you require a high level of sound protection even when your windows are open? WICONA has found a solution for an issue that at first appears irresolvable – with WICLINE 215. And this innovative coupled window structure achieves even more with its values relevant to building physics, which are similar to those of a double façade. WICLINE 215 combines a turn/tilt window that opens inwards with a parallel projecting window that opens outwards. This construction increases the user’s comfort many times over: individual ventilation, integrated sun protection and automatic control for night-time cooling ensure a pleasant atmosphere in the room. Furthermore, this applies equally to new buildings and renovation projects.


The advantages of WICLINE 215 at a glance:

• Double façade principle with all the advantages: turn/tilt windows inside, parallel projecting windows outside
• High level of user comfort and good atmosphere in the room thanks to air exchange up to 40 times in the space between the windows
• Windows that can be opened individually, no restrictions on use
• Very good Uw values for each element, from 1.2 W/m2K up to 0.65 W/m2K
• Increased sound protection (39 to 57 dB with closed windows), significant reduction in sound even when windows are open
• Passive solar energy gain due to double-layered design
• Integrated sun protection, protected against dirt and weathering
• Night cooling possible if combined with the WICONA E-Tec drive in the inner sash
