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.

alwitra kerbs

Cross section of kerb 3020Cross section of kerb 1600

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.

Thermal properties: U value: 0.92 [W/m²K] Dimensions: Height: 160 mm Light opening size = roof opening size - 20 cm• Tapering 2 x 100 mm• Inclined inner wall

Thermal properties: U value: 1.0 [W/m²K] Dimensions: Height: 300 mm Light opening size = roof opening size - 20 cm • Tapering 2 x 100 mm • Inclined inner wall

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.

alwitra DayLuxe window

The high-quality flat roof alwitra DayLuxe window is another

component of the alwitra daylight system. Instead of the stand-

ard vent frame, it features a high-performance multi-cell frame

with a laminated safety glass pane (HR++). In combination

with an alwitra kerb and an alwitra rooflight, you get a flat roof

window, absolutely suitable for living spaces, with optimum

characteristics:

• Compatible with all alwitra rooflights

• Compatible with all alwitra kerbs

• Thermal insulation (U value: < 1.00 [W/m²K] or better)

• Airborne sound insulation Rw = 40 dB (for 1S)

• Fall-through resistance 1,200 J

• Available as fixed or ventilated version alwitra DayLuxe window on kerb 1620 with collar

The high performance combination of flat roof window and rooflight

Versions:Two versions of alwitra DayLuxe windows are available:

Fixed version:

The fixed version has a concealed latch in the frame. This

ensures easy installation on a standard kerb with fittings

practically invisible from the inside.

Due to special inner reinforcements, to a certain extent, hand

spindle or motor actuators from the alwitra product range can

be (retro)-fitted.

Bright perspectives: the alwitra DayLuxe window alwitra DayLuxe window with concealed chain actuator

The alwitra DayLuxe window can only be installed on an alwitra kerb in connection with an alwitra rooflight. Installation without an

alwitra rooflight (min. 1 shell) is not possible. All types of alwitra kerbs can be used for installation.

Ventilated version:

The ventilated version has a chain actuator concealed in the

frame of the alwitra DayLuxe window, which - "invisibly"

installed in the frame construction - ensures daily ventilation.

Thus, the ventilated version of the alwitra DayLuxe window can

be installed on all alwitra kerbs without any major modifica-

tions. A remote control is included.
