alwitra daylight systems
Light is playing an ever-increasing role in modern architecture, forming part of the
design and aesthetics of a building. In particular, natural daylight offers many
advantages: It is verified to have a positive physiological impact, it increases our well-
being and thus enhances our productivity.
In Germany, sufficient daylight for natural lighting is available between 8 am and 5 pm
on 85 % of all days. For optimal daylight integration into architectural structures, spe-
cially developed constructional elements are required combining both technical and
aesthetic aspects. Flat roofs provide ideal conditions for the installation of rooflights
or flat roof windows. They capture the natural zenith light and provide for sufficient
and even lighting inside the building, requiring relatively little space. alwitra daylight
systems shed the light where it is needed. For example, on a well-lit and comfortable
working place.
Many living and working areas do not get enough daylight and, thus, give an oppressive
feeling. Natural daylight creates a free and open atmosphere, practically at no operating
costs. Along with the sustainable lighting of rooms, daylight systems still offer a
"free-of-charge" co-benefit, i. e. room ventilation. Due to the thermal lift and the optimal
installation place, i. e. the roof, depleted air is efficiently vented to the atmosphere.
alwitra daylight systems come with numerous advantages:
• pleasant natural light
• if desired, excellent natural ventilation
• additional usages, e. g. access to the roof or natural smoke vent
With the new alwitra daylight systems, you will be on the safe side:
• comprehensive product range providing high flexibility
• outstanding thermal insulation characteristics
• easy and reliable installation
• comprehensive range of accessories
• system-compatible connection to alwitra waterproofing membranes by
means of kerbs with optional EVALON® or EVALASTIC® collars
• CE certified according to EN 1873alwitra kerb

alwitra kerbs are made of white
impact-resistant "window quality"
extruded polyvinyl chloride profi-
les. A special feature is the cellu-
lar system created by ribs that are
formed already during the extrusion
process of the profiles. This sophis-
ticated technology gives you several
advantages:
• The cellular system itself ensures
outstanding thermal insulation -
without any additional "fillings".
• When welding the corners, weld-
ing also includes the ribs. This
results in a very large welded area
providing high stability of the
corners as well as continuous
"thermal insulation", in particular,
in the critical corner area.

Flashing to EVALON® waterproofing
membranes or PVC type waterproofing
membranes can be done by direct weld-
ing to the kerb. For flashing, bituminous
waterproofing sheets or other types of
high polymeric waterproofing mem-
branes, as usual, these are taken up the
kerb and fixed accordingly. As a special
feature, the alwitra kerbs can be fitted
with an optional EVALON® or EVALASTIC®
collar for reliable homogeneous flashing
to the corresponding roof waterproofings.

alwitra kerb 3020The kerb 3020 is 30 cm high, making it particularly suitable for roofs with ballast (e. g. ballasted or green roof), without needing any further modifica-tions as regards the flashing height. It is tapered to the top by 20 cm, so because of the inclined inner wall, the light opening size is 20 cm smaller than the roof opening size.
Thermal properties: U value: 1.0 [W/m²K]Dimensions: Height: 160 mm Light opening size = roof opening size• Tapering 00 mm• Vertical inner wall
alwitra kerb 1600The kerb 1600 is 16 cm high, no taper-ing. This means a vertical inner wall, with the light opening size being the same as the roof opening size. Ensur-ing maximum daylight intake with a modern design.
alwitra kerb 1620The kerb 1620 is also 16 cm high, however, it is tapered to the top by 20 cm as is usually the case for classic rooflights. This means an inclined inner wall, with the light opening size being 20 cm smaller than the required roof opening size.

alwitra kerbs - as part of the alwitra flat roof system - can be
supplied with a factory-fitted EVALON® or EVALASTIC® collar.
This means that alwitra kerbs are already completely watertight
and, after having been screwed to the substrate, need only to be
welded to the installed waterproofing membrane on site.
Absolutely no need for labour and time consuming detail work
on site like exact cutting-to-size of tapes, forming corners or
installing cappings.
You will benefit from shorter installation time and maximum
reliability, as the required auxiliary parts have already been
factory-fitted.

Opening and ventilation systems for alwitra rooflights
Rooflights can also be used for room ventilation, as a natural smoke vent with geometric cross-section or for providing access
to the roof. For all types of opening, in general, a vent frame is required where all necessary parts are included and prefitted.
For available standard configurations and combinations please refer to our current price list. Further configuration versions on
request.
Example of manual opening
Example of a motor opener with chain actuator
Example of a roof hatch with manual spindle
Manual opening (manual telescopic spindle)This is the most simple way of opening. The manual telescopic
spindle is hooked to the brackets at the kerb and the vent frame.
The rooflight is opened by turning the optionally available crank
handle. If the side length (light opening size) exceeds 130 cm,
a tandem version with two interconnected spindles is installed.
For some versions, manual opening can be combined with a roof
hatch function.
Electric openingAn electric actuator 230 VAC provides significantly more com-
fort. You can control the actuator with a switch or an optional
remote control. As with the manual opening, if the side length
(light opening size) exceeds 130 cm, a tandem version with two
electrically interconnected actuators is installed. For some
versions, electric opening can be combined with a roof hatch
function.
Roof hatch (manual operation)alwitra rooflights can be installed as roof hatches with ma-
nual opening to provide access to the roof e. g. for the chim-
ney sweep or for maintenance and repair works. Gas springs
on both sides facilitate the opening and closing of the roof-
light. Along with the roof hatch function, the system can also
be combined with the options of a manual spindle, electric
opening or natural smoke vent.

alwitra natural smoke vents for stairwells: reliable and safe.
The electronically controlled smoke vent system, along with its lighting and daily venti-
lation function, provides a geometric smoke extraction area and thus safe escape and
rescue routes, pursuant to the federal state building regulations (Landesbauordnung
- LBO).
With maintenance-free 24 V DC motor openers with 400 mm or 500 mm lift, virtually
all alwitra rooflights can be equipped with this additional feature. A great combina-
tion of all positive characteristics: bright stairwells through optimal natural lighting,
fresh air through daily ventilation, and, if necessary, the safety of a low-smoke stair-
well.
Optionally, depending on the size, the rooflights can be fitted with a lifting mechanism
(with gas springs) for roof hatch function. A simple unlocking mechanism allows exit to
the roof.
