KC A001 Suspension System
Knauf KC A001 Ceiling System must be installed in accordance with Knauf 's recommendations.
When creating an airtight space, methods for the reduction of potential “ceiling lift ’’ should be considered.
Mark the position of the ceiling line with a Chalk Line. Knauf UD channels should be secured to the walls at the required heights, at maximum 609mm centers and 50mm from the ends of channels.
The Knauf UD forming the perimeter and the Knauf Main C Channels do not need to be mechanically fixed together.
Select the fixing centers suited to the ceiling load. Fix with Knauf approved ceiling dowel to the structural soffit. Use the Knauf L - Angle or wire and fix to the approved ceiling dowel.
Primary Support Channels – C Channels
The centers of the primary support channels should be aligned at the required height.
Knafu L - Ange should be fixed to the Knaud Main C Channels with two Knauf LN Wafer Head Screws
Splicing of the Main C Channels
If straight lengths of Knauf Main C Channels need jointing, place the channels back to back, with a minimumn 609mm overlap, and fix with two Knauf LN Wafer Head Screws.
Hat Furring Channels
The Knauf Hat Furring Channels should be positioned at 406mm centers within the perimeter channels to coincide with the abutments of the boards, which wil lbe fixed later.
Connect the Knauf Hat Furring Channels to the Knauf Main C Channel by means of Knauf LN Wafer Head Screws.
If insulation is required, Installed once the primary support and the ceiling channels have been connected and before the boarding has started,
Knauf insulation as specified should be inserted above the primary support channels. Care should be taken to ensure that the insulation is fitted neatly without gaps at abutments or between different rolls.
Movement Control Joints
Create movement control joints where ceiling runs exceed 10m, coinciding where possible with movement joints in the surrounding structure.
Board Joint Reinforcement
Where the cut end of Gypsum board end’s reinforcement through the inclusion of additional Hat Furring Channels should be implemented.
A piece of Hat Furring channel should be located approx. 1 inch back from each board edge.
