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 & easier. It will also be easier to carry out inspections to installations above the ceiling as removal of the tiles will be easier. It is not recommended that ceilings are installed at a temperature consistantly over 50°C.

Grouping
The starting point for the fitting of the design panels is where a level line is achieved through the whole fitting area. The first row is fitted along a string in order for the perforated sections to be in line. The fitting is started in the middle of the room, as far as possible, and the design panels are fitted from the middle towards every side in order for the friezes to be equally wide. The panels are delivered undersized and must be fitted with a distance of up to 4 mm. The perforated sections must be in line with their own line and be perpendicular to the sections next to them.

Vapour barrier
If a vapour barrier is used, it is to be placed behind the furring.
|
Fitting
The design panel is screwed onto either wood or steel
at every 200 mm along the edge and section size of maximum 300 x 600 mm on the panel. The screws are countersunk, but it is important that they do not ream the surface of the panel. The screws are placed at least 15 mm from the edge of the panel in order to avoid damage to the edge. The cut edges are bevelled 3-5 mm. Use a 22.5° edge-planer for the bevelling. Sandpaper the cut carton.

Expansion joints
If there is a risk of movements between the ceiling and the adjoining building elements, expansion joints are used as connections. The maximum side length of a surface is 15 metres. Panels more than 70 m² must be divided with an expansion joint. Slip tape is fitted to the bottom of the joints, as expansion joints must only have two sealing points. The joint is made visible with an acrylic sealant. Mount the gypsum boards with edge rails towards the connection, which will give an exact finish and secure the attachment of the sealant.
