GTEC T-Bar Primary Main T 60x60mm rock mineral wool batt 100mm Movement control joints <strong>The</strong> continuity of the plasterboard and supporting structure should be broken by movement control joints: 1. Where the ceiling runs 10m or more in any direction 2. Where the ceiling crosses structural movement joints GTEC T-Bar Metal Angle GTEC T-Bar Cross T fixed vertically to TO DO TYPEFACE edge channels at top and bottom. GTEC T-Bar Cross T GTEC T-Bar Main T GTEC Movement Control Joint GTEC T-Bar Edge Channels GTEC T-Bar Main T GTEC T-Bar Edge Channels Wide flange for easier fixing of plasterboard Movement joints running parallel to the Cross T’s Leave a 12.5mm gap in the runs of either the GTEC T-Bar Primary Main T or Cross T as wide as the movement joint. Support the cut end of the primary Main T’s or Cross T’s with hangers no more than 50mm from the cut edge. When boarding the ceiling leave 12.5mm continuous gap along the line of the movement joint. Bulkheads Hangers at 1200mm or 900mm centres as required. GTEC T-Bar Cross T’s at 400mm centres. Ceiling Recess Ceiling recess detail incorporating a change in ceiling height is suitable for a maximum change in level of 600mm.

Synia is a unique plasterboard design from Lafarge that provides the ultimate flat ceiling in drylining. Traditionally, drylining plasterboards are manufactured with 2 tapered edges in order to create a seamless finish when jointed. For ceilings this has presented installers with the problem of extra planing, labour costs and time for the cut ends. Synia has been created with a unique edge design which, once fixed, reveals a 4 tapered edge for jointing. This offers the installer a faster, easier solution, resulting in the ultimate flat ceiling.
