The following points contain information for a profes-
sional attachment of the pipes as well as the consid-
eration of temperature changes.
The general rule is: Overall pipe length divided by the
minimum attachment distance. The minimum attach-
ment distance usually is 1 meter! In case of a poor
base, however, more attachment points must be pro-
vided. The fastening material is selected in accord-
ance with the characteristics of the wall (lightweight
materials, steel construction, concrete, perforated
brick, sandwich construction) (e.g. by Hilti or Würth).
