3 Installation Field
To properly assure a durable installation, various prereq-
uisites must be fulfilled:
●
For plain tile and similar roofings on roof battens a wa-
ter proof and diffusion resistant sarking (no vapor bar-
rier!) is required, with at least 24 mm strong counter
battens to assure proper backside venting (Fig. 8). If
the proper backside ventilation is not assured through
ridge or eaves, ventilations tiles have to be installed
horizontally above and below the collector field with a
spacing of approx. 90 cm.
●
For classic slate roofings on wood boarding an undam-
aged water proof and diffusion resistant sarking has to
be laid. Below and above the collector field a roof vent
should be provided for approx. every 90 cm.
●
Keep a minimum distance of one meter between col-
lector fields and roof structures that emit moist air, such
as chimneys, skylights, kitchen and air condition vents.
Otherwise there is a risk that additional moisture enters
the collectors through the ventilation openings in their
frames.
●
At least three rows of roof tiles should be kept above
and below the collector field.
●
The roof tile rows above the collector have to project
for at least 150 mm over the upper flashing sheet.
Procedure: For plain tile or similar roofing use the existing
roof battens as support construction. Affix the required
additional battens according to the dimensions in Fig. 7.
and Fig. 8.
For slate roofing without underlying roof battens install
the collector fixing clips and all other components directly
onto the base.
Ideally determine the installation field so that on one side
there will be a distance of approx. 35 mm between collec-
tors and roofing slates. On the other side cut tiles/slates to
size. For large roofing areas it is recommended to average
out the collector field.
