Indicative material estimate, not a tested partition design. Verify all details with the system manufacturer.
Frequently asked questions
Practical answers before buying materials.
Yes. Boards and screws are counted for the chosen face; frame and cavity insulation remain unchanged. An open frame is not a tested acoustic or fire-rated partition.
The cutting plan reuses suitable sheet and profile offcuts. Door cut-outs are not assumed reusable. A spare sheet is shown separately only if the cutting margin is small.
For two layers, offset joints between layers and opposite faces. Fill inner-layer joints where required by the selected system.
No. Confirm height limits, stud centres, openings, fire and acoustic performance with a qualified professional and the complete system documentation.
