Processing/practical tips

In order for rock wool not to lose its insulation effect, it should not be exposed to moisture and water, for example at the base of exterior wall structures.

The basic principles are: the substrate must be dry and clean, loose material must be removed. The wall must be flat enough. The substrate must not be exposed to moisture subsequently. No rising damp is permissible.

Installation: the adhesive can be applied all over the insulation panel. On a flat substrate the adhesive is applied with a combination of edge beads and dots; if the substrate is not quite flat, it is applied all over with a serrated trowel. Afterwards the panels are laid edge to edge and pressed firmly in place. In addition to bonding, they must be secured with suitable dowels.
