Overview
How this system works
WDS 6S combines a 70 mm depth, six chambers and glazing capacity up to 40 mm. Its visual distinction is the reduced lower frame and sash height, allowing a larger glazed area at the bottom. WDS describes options for multi-family housing and energy glazing; the system alone does not mean the glass uses a different technology.

Where it fits
Consider 6S when more daylight and a lower visible frame matter for a particular opening. Compare the frame height and glazing proportion on a drawing, then select opening, glass and hardware for the room. Request an exact-size layout for a fair comparison.
What to compare before choosing
The clearest visual difference from 5S is the lower profile, not the photo background colour. Show frame proportions and visible glass. Compare 7S separately by profile geometry and values in its technical documentation.

Frequently asked questions
How does WDS 6S increase glazing area?
WDS highlights a lower frame-and-sash profile. The final glazed area depends on window dimensions and layout.
Will any glazing up to 40 mm fit?
40 mm is the published system limit. Check glass weight and build against the window dimensions and configuration.
