Celenit panels are the most suitable material for resolving this type of problem, due to their ability to transpire and their long lifespan.

The extent of the damp will determine the kind of operation required.

• Light humidity: face the wall with plug-secured panels

• Very humid walls: fix the panels to a treated wooden lathing or, even better, to galvanised metal profiles.

It is advisable to make ventilation holes in the cavity. The plaster applied to the panels must have high transpiration properties.
