STEP 1: Preparation
Establish finished height of the ceiling allowing for any services below joists or truss chords. A minimum of 25mm between the truss chord/joist is recommended for acoustic separation.
STEP 2: Perimeter Channel
Fix the perimeter channel/angle to the ribbon or top plate with 8 gauge 12 x 25mm wafer/flathead self-drilling wood screws at 450 centres max. (Long leg of channel to the bottom).
STEP 3: Setout
Set out batten centres to suit plasterboard system type and thickness in accordance with the plasterboard manufacturers recommendations.
STEP 4: Fixing Clips
Using the travel slots, secure the direct fix clips to joist/truss chords with a single 8 gauge 12 x 25mm wafer flathead self-drilling wood screws or 30 x 2.5 mm galv clout. Leave fasteners slightly loose to allow for final adjustment.
STEP 5: Batten Installation
Offer one side of batten flange to clip stirrup and in one motion squeeze the flanges together and rotate upwards to click batten into position.
STEP 6: Perimeter Fixing
Secure batten from the underside through perimeter channel leg or angle with two wafer head screws 8 gauge – 16 x 12mm minimum.
STEP 7: Leveling
Once string lined, straight edged or rotary laser levelled, ensure the batten plains are straight, level and uniform. Fix off the direct fix clips in the additional holes provided as well as tightening the fastener in the travel slot.
