How are the wall heating boards fixed?
The wall heating boards can be both screwed and glued. They are either screwed onto solid wood surfaces (such as OSB panels) or onto strip-shaped substructures (classic wood or aluminium battens). Normal drywall screws (phosphated) in the size 3.9 x 45 mm can be used for this purpose.
Gluing is carried out on full-surface and flat substrates such as, for example, on brick masonry that has already been plastered over the entire surface.
The ceiling heating can only be screwed and not glued. Otherwise, the procedure for ceiling heating is the same as for wall heating, with the only difference that the substructure must be designed in half the grid width of the tiles (i.e. 31.25 cm).
