According to EN 13964 - Annex F, Tonga® A 40 ceilings are classified as C/90N/m² for dimensions 600 x 600 / 1200 x 600 / 1200 x 1200 mm. This value should be kept in mind if any mineral wool is to be laid in the plenum.

Implementation and maintenance


• You are advised to ensure that air can circulate between the rooms and the plenum to balance the temperature and pressures on each side of the ceiling.
• Tiles can be cut with a craft knife without generating any noise or dust.
• The direction in which the panels should be installed is indicated on the back of the panels.
• Contact us if any mineral wool is to be laid in the plenum.

The ceiling surface does not retain dust, which makes the panels easier to clean. The ceiling can be cleaned using a light brush or a vacuum cleaner. This type of cleaning will help extend the service life of the ceilings.
