- 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.
- Alizé® ceilings are fitted on T15 - T24 grids.
- 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 surface of Alizé® ceilings does not retain dust, which makes them easier to clean.
- Alizé® ceilings can be cleaned using light brush / vacuum cleaner.
- This type of cleaning will help extend the service life of Alizé® ceilings.
