DECISION SHEET
When to choose W111
Best suited to
Compact, straightforward internal partitions with one board per side and the fewest board layers in the W11 family.
Compare first with
Choose W112 for two layers, greater robustness or higher performance; move to W113 where the documented solution requires three boards per side.
Critical site checks
- ✓Fit acoustic seal beneath perimeter profiles and seal all junctions correctly.
- ✓Choose 400 or 600 mm stud spacing from height, board and system requirements, not merely to reduce profile quantity.
- ✓Keep board joints away from door and window corners, and inspect services before closing the second face.
