Control Joints

Control joints must be installed in walls and ceilings at a maximum spacing of 12m, or at control/ construction joints, whichever is the lesser.

Architectural features, openings, and the like may be used as control joint set out points.

Rondo ‘P35’ or MBS ‘PXJ-30’ are suitable control/expansion joints.

Control joints are centrally located across the 15mm minimum gap between adjacent BGC Plasterboard sheets, and the flanges nailed at 300mm centres to the framing behind.

Control joints should be set at twelve (12) metres maximum, or at construction joints, which ever is the lesser.
