The PVC Wall Panel Joint Bar Trim sits between two panels along a flat wall, hiding the joint and creating a watertight seal between them. Use it on long wall runs that need more than one panel width, or wherever you want a deliberate vertical line as a design detail.
Tongue-and-groove panels (250mm wide) interlock with each other and don't usually need a joint bar between them. Joint bars are most useful for joining wide-panel formats (1m or wider) on the same flat wall, OR as a deliberate design feature.
Will it look like a deliberate design or like a hidden joint?
Depends on your trim choice: White on white panels = nearly invisible. Silver or Black on white = deliberate vertical detail. Decide whether you want it to disappear or stand out.
How many do I need?
One per joint between two panels on the same flat wall. For tongue-and-groove panels, usually zero needed.
Can I use it instead of internal corner trim?
No — the joint bar is for two panels on the same flat wall. Internal corner trim is for panels meeting at 90°.
