These square
inspection boxes satisfy the requirements of FLL standard
values, and can be manufactured in various heights up to 30 cm.
Inspection Boxes
(Intensive)
These
inspection boxes are round, and of larger dimensions than the
square ones to ease access to the down pipes. These boxes, which
comply with FLL standards, have a minimum height of 30 cm.
Inspection Box Extension
Element
Extension Elements are particularly suitable for intensive
roof-installations on different levels. Installation is
tool-free and clips along two sides ensure a precise and
problem-free extension of the inspection box. Height: 10 cm.
Cat-Scarecrow
The
VS cat-scarecrow can easily be attached to the stainless steel
surface water grating, and protects your plants from uninvited
avian guests.
Drainage Openings
Drainage openings
are precut. They should be pressed out prior to installing the
drainage pipe.
Lockability
Lockable
boxes prevent unauthorized opening of the lids, and locks offer
additional security against wind suction and accidents. They are
especially recommended for intensive planting projects, which
may also be enjoyed by children.
Natural Stone Cover
To
satisfy the most stringent requirements, inspection boxes are
also available with a robust and frost-resistant multicoloured
granite cover.
KSE Inspection Boxes
(Square)
APP
eco-inspection boxes are manufactured in accordance with the FLL
Guidelines for the Planning, Execution and Upkeep of Green-Roof
Sites (FLL).
Guidelines For Roof Planting
"As a
rule, roof-outlets should be located away from vegetation areas
and free from gravel. Where roof outlets are located within
vegetation areas, an inspection shaft will need to be installed,
to allow inspections to be carried out, to prevent contamination
and to stop plants from growing over the outlet" (FLL).
Underground Garage
Boxes
Appropriate for:
Passable garage roof gardens
Roof gardens in locations susceptible to damage.

KSA Fascia Boxes
Fascia boxes
are installed above down pipes near the parapet and in front of
drainage outlets.
There are two pre-defined cutting lines on
the fascia boxes. These are to accommodate alternative sizes
of fillets.
DIN 1055
(part 4) notes that parapet areas can be subject to extreme
wind suction. For this reason, fascia box covers are hinged
and are not removable.
Correct Installation
For
areal drainage, inspection boxes have to be placed on the
water-carrying layer: they need to be placed on the protective
layer for linear drainage. No additional fixing is required.
The boxes are surrounded with round gravel to prevent the
cultivated areas washing way. Do not run the filter-fleece up
along the sided of the inspection boxes, because this might
lead to standing water building up in heavy rain.
Drainage Of Surface Water
Drainage of
surface water is essential. "Drainage facilities must be capable
of collecting both overflow from the drainage course and surface
water from the vegetation support course and of conveying it
away" (FLL). The openings may have a maximum diameter of 2 mm.
Drain Bar
Bars ensure
that the pipe remains attached to the inspection box.
Thermal Insulation
Thermal
insulation, made from 30 mm extruded hard polystyrene foam with
a thermal value of 0.027 W/mK is an optional add-on for every
inspection box.
