Secondary Carrying Channel

Horizontal member -Furring channel running cross-wise fixed to the Main Channel by the Locking key at max. 600mm* centres

Anchors/plugs

Used for fixing the Suspension system to the slabs and Furring channel Tracks to the wall respectively at max. 600mm centres

Drywall screws

Used for screw fixing the boards to the metal structures; available as self tapping or self drilling

Joint tape and Filler

Used to get a even smooth and homogenous surface at the joints

Sealant

Applied at the perimeter areas, to achieve the necessary fire and acoustic performance

Insulation

Used as quilt covering the entire ceiling system will increase sound insulation in the void.Rockwool slabs are used to enhance the fire insulation.
