Wherever external facade insulation cannot be carried out, internal wall insulation is appropriate. The PAVADENTRO insulation board was specially developed for internal renovation of old buildings. It reduces moisture formation in existing building components to a minimum and provides a comfortable internal environment.
Where the wall is out of true by more than 8 mm, a levelling coat such as red chalk must be applied to the wall and allowed to dry completely before further work. At unevenness of less than 8 mm, the PAVADENTRO board is bonded directly to the prepared substructure by means of a level, capillary active adhesive coating.
It is essential that the adhesive coating be placed between the solid wall construction and the insulation board. The adhesive coating is applied to the entire surface of the PAVADENTRO board and gently rubbed in, and the board is then bonded to the dry wall or levelling layer.
Additional fixing of the boards takes place immediately, while the adhesive coat is still damp, or only after the adhesive coat has set. On masonry substructures, this is carried out with at least three fixing anchors for masonry (insulation plate anchors) per board.
Finally, the PAVADENTRO insulation boards are plastered with a mineral-based internal plaster system using, for example, red chalk or clay, in accordance with the plaster manufacturer‘s specifications.
