Overview
How this system works
WDS 8S is an 82 mm system with six chambers, three seal contours and glazing up to 44 mm, according to technical materials for the range. Its sash has a classic rounded line. It is deeper than 5S or 6S; whole-window thermal or acoustic results need a specific glazing build, size and test configuration.

Where it fits
When comparing 8S with a shallower profile, check depth, frame placement and reveal details. Then confirm glazing thickness and hardware. The image should show the 8S profile and a conventional hinged window so it is not mistaken for a slider.
What to compare before choosing
WDS describes 76 MD as gradually replacing 7S and 8S. Compare 8S with 76 MD by chamber count, seal contours, depth and documentation, rather than unsupported claims such as “warmer” without a value for the actual window.
