Overview
How this system works
WDS 7S is a 70 mm hinged system with six chambers, described in the technical materials for the range. Manufacturer sources show glazing and sash geometry options; performance depends on the profile and tested build. Compare the exact section, seal number and placement, glazing capacity and hardware.

Where it fits
For a replacement, check the current frame and available installation space before choosing by series name. If 7S is proposed, ask for the profile code and the specification for the planned build to compare glazing capacity, sash size and tested results with other WDS options.
What to compare before choosing
WDS manufacturer materials describe 76 MD as gradually replacing 7S and 8S. This page therefore explains the 7S construction without calling it the newest option or claiming availability. The comparison should show profile and seal differences rather than reuse generic copy.
