The terrace grilles are installed after the roof has been
sealed and after the protective, drainage and filter layers
have been laid, always centrally over every down pipe. The
removable, hotgalvanised grille eases maintenance and care
of the down pipes and leads the water away perfectly.

Because of height adjustability, it is possible to ensure
that they are installed to match exactly flush with the top
of the surrounding units. The height is infinitely
adjustable between 8 and 12 cm. One needs a spanner for
adjustments to the appropriate height and to flush with the
surroundings. A nut must be released and, after the
adjustments, be tightened up again.

APP patio grilles, which match
the most common size of terrace tiles on the market, comprise
three elements:
- The base, out of respect for the environment, is
high-quality plastic made 100% from recycled material.
- The grille (40mmx10mm mesh) is fully galvanized or made
from stainless steel to guarantee a long life.
- A hot-galvanized adjuster provides heightflexibility.

Holes have been cut in the factory into the 8cm-high
patio grilles for connection to the drains. These need to be
broken open before insertion of the drainpipes.
After insertion of the drainpipe, a bar ensures that it
remains fixed into the patio grille.
