Wall and ceiling expansion joints: recessed and exposed details
Wall and ceiling joints should match the substrate, movement direction and finish build-up. A suspended ceiling detail needs coordination with its support system, not only a matching visible cover.
Selection considerations
Locate the structural opening relative to boards, framing and finish layers. Record whether the joint is recessed or surface mounted and which side carries each fixing. For suspended ceilings, check the continuity and independence of framing across the movement line.
Compare straight and corner variants separately. A similar-looking cover can use a different backing arrangement at a wall-to-ceiling intersection. Provide access where maintenance or inspection is required. Avoid closing the movement zone with rigid finish material simply to produce a neat-looking seam; the approved detail must preserve the intended movement path.
Before you specify or order
- Coordinate framing and joint line
- Select straight or corner geometry
- Keep the movement zone free
