Square edge boards meet with a straight face and are useful where the joint is hidden, detailed with a trim or finished by a method designed for that profile. Tapered edge boards create a shallow recess for tape and joint compound.
Choose the edge with the finish in mind
| Edge | Common planning direction |
|---|---|
| Square Edge | Simple edges, concealed joints, trims or selected ceiling details. |
| Tapered Edge | Taped and jointed surfaces requiring a flatter finish. |
| Tegular or special edge | Modular ceiling panels installed into a compatible grid. |
Do not mix profiles casually
Changing edge profile after production can affect the jointing method and visual alignment. Put the edge requirement on the purchase order and sample approval.
Sample before bulk approval
Build a small mock-up using the proposed tape, compound, screws and finish. This exposes joint shadows and edge mismatches before the complete shipment arrives.
The edge field is a small line in a datasheet, but it has a large effect on installation and finish quality.
