Installation instructions • 315 mm wide MDF-panels

 

Please read these instructions carefully before installing the panels!

Before installation

• Please note that the panels are intended only for use indoors, and they should not be allowed to come into direct contact with water.
• Possible faults appearing in the products can only be used for reference before they have been installed.
• We do not recommend that the ceiling panelling is used with ceiling heating.
• From the same production batch: combined large surfaces. The production batch number is situated on the bottom of the lower panel.
• Room temperature and humidity must be normal, the room temperature about 20°C and the relative humidity percentage of the air approximately 40%: i.e. the doors and ceiling of the room should be dry, and the windows and doors glazed.
• The panels should not be subjected to continuous temperatures of over 70°C.
• The temperature and moisture of the panel must be allowed to even out with the same temperature and moisture of the installation environment before mounting. The packages do not need to be opened entirely: it is enough that an opening is made at the ends of the packages so that possible moisture can escape.

Platform

• The lathing space should be precisely 300 mm, as the panels are installed parallel with the underboarding so that the ceiling does not start to sag. The thickness of the strips is 45x45 mm (min 20x40 mm).
• Ensure that there is enough air circulation behind the panels. If needed, remove the underboarding or mount the counter-boarding.
• Ensure that the underboarding is straight, regardless of the unevenness of the ceiling.

Mounting

• We recommend a nailing tool that incorporates compressed air for panel installation.
Use at minimum a clasp that is 22 mm long, 9 mm wide and 1.6 mm thick. (With 8x160 and 10x195 panels, use a clasp that is 22 mm long, 11 mm wide and 1.6 mm thick)
• The staple should be shot sideways along the groove into the protruding base rabbet.
• To allow installation of the panels, the staple must remain at the same level with the tongue and groove. The staple must not be sunk deeply inside the tongue and groove, as in that case the panel cannot be closed properly.
• Leave room for expansion of at least 12 mm between the panels and the wall or the surfaces bordering the other panel. If the length or width of the roof pane exceeds 6 metres, 2 mm of expansion room must be added for each exceeding metre. The seam should be covered with crown or fold moulding.

Installation

• By positioning the seams of the end tongues and grooves, you can affect the appearance of the ceiling. You can make patterns on your ceiling by positioning the site of the end tongue and groove.

 

Safety guidelines

• No lights or other similar heavy objects should be connected to the panel: rather, they should be installed directly to the base batten.
