Storage & Installation
Storage and installation should not be carried out in rooms with a relative humidity greater than 70%, unless otherwise stated, see section Moisture.
It is equally important to take account of other work such as technical installations before installation of the ceiling is carried out. It is important for the end result that the ceiling tiles are installed at right-angles, this also makes installation quicker and easier. It is not recommended that ceilings are installed at a temperature consistantly over 50°C.

Layout
Contrapanel is fixed on a level steel furring system of the CD-2 kind. Normally, the ceiling surface is divided from the centre of the ceiling, so that any cut panels at the edges of the area get the same dimensions.

Furring system
The system consists of primary runners at max 900 mm c/c, and secondary runners at 300 mm c/c. Along the walls and edges the wall profile UD 28 x 27 is fixed, which is secured to the furring at max 400 mm. The top part of the hangers, of the nonius model, are secured to the above construction at 900 mm and attached to the primary CD-60 runners with the lower part of the hanger. The cross connector is placed per 300 mm and the underlying secondary profiles are secured into them. The short edges of the panel must be supported in its entire length of the furring system.
|
Fixing
The Contrapanels are cut by a fine tooth saw or a Stanley knife. Cutting should always be done from the front side of the panels. Screw fixing of the Contrapanels is always directly through the panels and min. 10 mm from the edges. The cut perimeter of the finished ceiling can be covered by an edge profile.
