Glass Architects, designers, and artists appreciate natural materials. Their unmistakable
appearance and haptic features fascinate both users and observers. In this connection,
glass also moves into focus - a material whose diversity and emotional potential
distinguishes a range of widely differing building projects.

Real beauty survives for thousands of years
Architecture with glass: leaded glass
windows have been widespread in
Europe since the middle of the 11th
century.
It is single-colour, multi-colour or completely colourless. Highly
reflective or shimmering matt. It can be polished, engraved,
etched, printed or sandblasted … There is absolutely no doubt
that the mixture of quartz sand and other mineral raw materials
has proven to be a material with a large choice of variants that is
used for a huge variety of purposes.
Glass has been impressing people for 9,000 years now: even
back then, obsidian, a type of glass that was produced naturally
in the course of volcanic eruptions, was used for tools such as
wedges, blades or drills due to its high degree of hardness.
Naturally, it was a long way to go until glass was produced by
melting and forming. The oldest glass container that can be
dated with certainty was produced in Egypt in approx. 1450 B.C.
Indispensable today in the window manufacturing sector, glass
possesses an unlike greater aesthetic potential: especially in
facade construction, glass is captivating mainly due to its
transparency and its ability to communicate with its surroundings
by means of reflection.
Benefits of glass
• Versatile interior and exterior application is possible
• Wide colour spectrum
• Wide range of surface finishings possibilities
• Ecologically compatible building material
• Durable and easy to clean
• Robust and weather-resistant
• Backlighting can be employed
• Reflects its surroundings

Sustainability
is the best policy
Glass is not only a remarkable material in terms of its appearance,
but also due to its flexibility and durability – its life span is
impressive. Glass facades are as weather-resistant as they are
easy to take care of: rain, snow, and ice are unable to damage
them. Glass is easy to clean, requires only little maintenance, and
can be recycled. A further plus point in relation to sustainability:
in the opaque StoVentec Glass system, even the carrier boards
are made of 96% recycling glass.
Sustainable material:
glass is extremely hardwearing, weather-resistant,
and up to 100% recyclable.

10 | Expert interview
Expert interview Due to its properties as well as to its diverse areas of application,
glass is probably the most sophisticated building material for architects. It is not the
material itself that is so fascinating, it is the possibilities it offers as a composite
material. Martin Haas, in the course of his activities as a partner at Behnisch
Architekten, has gained a lot of experience with this building material. A brief
insight into why his office likes working with glass.
Expert interview | 11
Expert interview
Martin Haas,
Behnisch Architekten
Sto: The construction of a glass facade is more complex than
that of a massive brickwork facade, the costs are higher and the
climate of the interiors is more difficult to regulate. What induces
Behnisch Architects to use glass on a large scale nevertheless?
Martin Haas: Transparency and lightness, the unobstructed
connection between the interior and exterior, the possibility of
creating open, inviting rooms are significant aspects of our
architecture. The wonderful view, the shadows of passing clouds
on walls and floors are features of high-quality rooms and the
basis for creating an architecture that enriches the everyday life
of the user. Glass influences work in our office in a way barely
any other building material does. Reflections and light refractions
on opaque glass surfaces allow for exciting designing possibilities.
In our project in the Chamber of Commerce in Hamburg, we
were able to give the whole building an almost immaterial
appearance.
Sto: Glass as such has been explored as far as possible, whereas
the possibilities of the further development of glass as a composite
material are seemingly unlimited. Chromogenic and electrical
chemistry, aerogels, nano technologies are specialised terms
based on complex sciences. As an architect, how do you keep
up with the latest state of the art?
Martin Haas: For us every project begins with a basic analysis,
also of materials. We often develop new possibilities of application
in cooperation with manufacturers, for example the LED technology for Unilever. This way we automatically keep up with the
state of the art in technology.
Sto: For a long time it was especially the available maximum
size of individual glass panels that was the primary problem
for manufacturers, whereas today it is, above all, questions concerning energy that have to be answered. In your opinion, what
is the energetic potential of glass as a composite material that
has not yet been fully exploited?
Martin Haas: The topic of "sustainability" has been influencing
the way and manner we have been developing architecture for
some time now. The extravagant use of glass as a the dominant
building material in facades has been under some criticism from
an energetic aspect. Glass still has invaluable benefits in light of
the possibilities of different building materials and on consideration
of the climatic impacts of a specific building site as well as the
12 | Expert interview
orientation and alignment of a building: the unobstructed visual
link to the exterior and the optimum exploitation of daylight in
the interior is achieved by no other building material. Heat loss in
winter as well as undesirable solar heat gain in summer can be
controlled more easily by new technologies like vacuum or triple
glazing or a more efficient sun protection system. When
employed in accordance with these features, glass is an irreplaceable building material especially in ecological architecture.
Sto: Many architects dream of the "intelligent skin": glass that
not only provides protection, but that can also communicate –
much of this can already partially be achieved, other concepts are
still a vision. What innovations are you hoping for for the future?
Martin Haas: One goal is to reduce the number of materials
and trades in a building and to simplify its actual construction.
However, this would entail a revision and re-structuring of
lighting concepts. A new aspect here is the option of utilising
the facade not only as a source of daylight, but also as a source
of artificial light. It is a worthwhile notion to replace the slowly
disappearing daylight with artificial light in the same element in
the evening hours. A room situation optimised to a specific light
situation would function both during the day and in the evening.
Therefore , the facade of the future does not only provide protection from the sun, solar panels for energy generation, deflecting
elements in the top area of the facade for daylight control and
elements that can be opened for ventilation, but it also includes
lighting elements for basic lighting at night as well as heat
exchangers and elements for mechanical 2-way ventilation.
Moreover, we also see a lot of structural, material-saving benefits:
the facade, as a technically complex and precisely crafted element,
has a pre-installation from the onset due to the control elements
such as solar protection that can also be used for lighting fixtures.

14 | Inspiration
Inspiration Already the composition of the individual elements leaves a great scope
for creativity. Moreover, the arrangement of the elements or the combination with
other materials opens up unlimited design possibilities. And not only on the facade.
Inspiration | 15
Creativity lies between the lines
As the size of facade panels is limited, joints between the single
elements cannot be avoided. However, this does not necessarily
mean a "break" in the design. Joints can have a separating,
organising, structuring or rhythmic effect and thus lend a special
quality to a building. The creative use of this flexible "void"
has long since been a topic in architecture. Joints can run
horizontally or vertically, vary in their width, be arranged
symmetrically or asymmetrically.
Huge range of variants: only three
examples of how joints can be used
to create appealing facades.

Together they are strong
Sometimes it's all about the mix.
Different materials and surface
textures make balanced facade
designs possible. The combination of
glass with natural stone or render
on a continuous sub-construction
creates either separation or a link.
The alternation in material sets
accents and formulates citations.
Different types of glass and panels, a
large range of natural stones as well
as an almost unlimited choice of
organic or mineral render textures
in all the 800 colour shades of the
StoColor System allow for a multifacetted interplay of haptic and visual
features.
A special variant of this interplay is
the combination facade, in which not
only the surface changes, but also
the underlying system; for example
in the linking of RSC with a classic
EWIS. Sto provides numerous
connection details to achieve this.
In the system: from glass to
natural stone – changing the
material without changing
the system.

For lovers
of inner beauty
The fact that StoVentec Glass facades are resistant to storms and
cold temperatures and still cut a good figure is one thing. But
StoVentec Glass can also be used in the interior of a building
where it is protected from the impact of the weather. With one
and the same system, StoVentec Glass guarantees a continuous
material flow from the exterior to the interior.

Perfectly integrated: the
interplay of printed glass
panels, glass panels with
functional elements and
overhead glazing.
StoVentec Glass has also been tried and tested in overhead
glazing. Sto places the highest demands on safety and quality:
as the carrier board and the glass panel are bonded to form an
inseparable sandwich panel, there is no danger of glass splinters
falling down if the glass is damaged. This allows for overhead glazing both on the exterior and in the interior of a building. With
appropriate planning, functional elements such as lighting can
be integrated without any problems.

Material variants StoVentec Glass Panels are customised pieces which are
predominantly produced manually according to the wishes of the customer. In
terms of shape, colour, or finishing techniques, the range of designs is impressive.
Material variants | 25
Precise craftsmanship
To the millimetre: this is where the
StoVentec Glass Panels are cut to their
individual format.
StoVentec Glass Panels are not available "ex warehouse". They are
customised pieces that are manufactured individually according to
the construction project and wishes of the customer. This is
accomplished at the Sto panel production facilities in Lauingen,
predominantly according to good, traditional craftsmanship. This
allows for a wide range of special shapes extending to panels with
cut-outs for functional elements.
The carrier boards for the panels are also made in Lauingen.
These consist of expanded glass granulate, an environmentally
friendly material that is obtained to 96% from recycling glass.
First the boards are cut to the required format. The edges are
sealed by hand in the course of several work steps. The agraffe
profiles are then screwed to the rear of the carrier boards, the
glass panes are mounted and grouted.
On the construction site, the panels are suspended from the
sub-construction without extensive time investment and regardless
of the prevailing weather conditions.
Quality check: throughout the
entire production process the
panels are repeatedly inspected
to make sure they are free of
defects

A projection screen for wishes and ideas
The individual character of a building facade is not only unfolded
by the interplay between colours and shapes, but also by the
specific surface design. Also in this case, StoVentec Glass facades
prove to be an ideal projection screen for a huge range of ideas.
Screen printing offers multiple possibilities for surface refinement.
Almost any desired motif can be applied to the rear side of the
glass panels using this procedure, whether these are patterns,
illustrations, photos or corporate logos.

Form follows inspiration
StoVentec Glass Panels are available in many different forms.
For example, panels can be supplied in square, rectangular,
trapezium, and parallelogram shape. Due to the non-visible,
mounted suspension system, only fine joints structure the
homogeneous surface area – entirely without frames, rails or
point brackets. The panels also bear up to any critical inspection
from close proximity thanks to their customised production. As
the distance to the wall of the building can be adjusted precisely,
the StoVentec Glass Facade system also enables levelling of
potential unevenness.

Systems The StoVentec Glass Panels naturally leave a good impression at first sight.
With StoVentec Photovoltaic, the facade even becomes an electricity supplier. But the
inner values are also convincing: the sub-construction reduces thermal bridges and
consequently the insulant thickness. And the rear ventilation provides even more
benefits: optimum protection against noise, cold, heat, driving rain, and moisture.
Systems | 35
Beautiful shell, strong core
StoVentec Glass is a ventilated rainscreen cladding system
consisting of a sandwich element, thermal insulation, and a
stainless steel aluminium sub-construction. This can be mounted
onto virtually all bearing walls. A circulating air layer remains
between the suspended panels and the mineral wool insulation
mounted directly to the substrate. In this way, a wall structure
which is optimal in terms of building physics with thin construction
depth is achieved.
The tempered safety glass is completely adhered to a carrier
board to produce an inseparable sandwich panel. This rules out
any risk of pieces of glass dropping from the facade, even in the
event of glass fracturing.
The carrier board itself is made of expanded glass granulate, a
material that is as light as it is environmentally friendly since it is
obtained from recycling glass. With a weight of approx. 30 kg/m2,
the system is light enough to be employed in older existing
buildings.
The suspension of the 30 mm thick glass modules on the rear
side is non-visible. The modules are available in all required
dimensions up to a size of 1250 x 2600 mm. The individual
panels are factory-produced according to the individual specifications for simple attachment to the sub-construction on site.
Oversized formats are possible in individual cases with special
approval.

This is how facades are energised
Photovoltaic, the direct conversion of solar energy into electricity
is one of the most environmentally friendly methods of generating
energy – no exhaust gases, no consumption of fossil resources.
With StoVentec Photovoltaic, this technology can even be used
via the facade. Developed in close cooperation with Würth Solar,
a special photovoltaic module is integrated into the facade as
a surface. StoVentec Photovoltaic does not only insulate the
building and reduce its heating requirements, it also generates
energy from solar radiation at the same time.
The modules can be supplied in six different colour shades.
The degree of the light reflection has an impact on the efficiency.
Depending on the colour, an annual electricity yield of
45 - 75 kWh/m² of photovoltaic module can be generated. This
means that with a StoVentec Photovoltaic Facade of 60 - 100 m2,
the average energy requirement of a Central European family of
four can be covered.
At the factory, the photovoltaic modules are bonded with the
StoVentec carrier boards to form sandwich elements. They must
be suspended from the sub-construction and connected to
the inverter. The active PV modules are available in the sizes
1200 x 600 mm or 600 x 1200 mm; in case of the maximum
possible panel format of 2600 x 1250 mm, several PV modules
are bonded onto a carrier board.
But the visual experience is not neglected in the face of environmental friendliness and cost-effectiveness: all colour shades of
the StoVentec Photovoltaic Panels are supplied with a pinstripe
effect, which creates an aesthetically appealing design.

Facade system meets eco system:
Palma Aquarium, Palma de Mallorca
"Aquarium" appears to be a sheer understatement for the structure in Palma de Mallorca, located in the
western part of Playa Palma. Erected in 2007 on a site of 42,000 m2, the building complex accommodates
55 aquariums, each a living marine ecological system. Around 8,000 specimen of more than 700 different
marine creatures from the hammerhead shark to the sea cucumber splash about in 5 million litres of
water – a conservation of endangered species of marine fauna and flora. Even the architecture gives the
impression of a living organism, instead of a rectangular geometry with edges and corners, it is organically
and dynamically bent in its structure. It was a real challenge also with regard to the facade system, but it
was mastered by using StoVentec Glass. The system proved to be an ideal solution also in this unusual
context. Because the even, rectangular elements can also be employed in bent and "sweeping" layouts.
Manufactured in the matching sizes, the coloured glass panels can be fixed to the rear side thanks to their
non-visible agraffe profiles.

Archive of the State Archaeological Museum, Schwerin
Erected from 1859 - 1862, the buildings of the "Old Artillery Barracks" in Schwerin are for the most part
in good shape and are currently used by local authorities. The riding hall is a different matter: this hall was
actually supposed to be converted into a sports hall – until the construction project was stopped, leaving a
dilapidated brick ruin behind. It wasn't until a few decades later that this ruin was secured against collapse
by the Landesdenkmalamt (State Office for the Protection of Historic Monuments) and presented with an
unlike neighbour on the other side: a "Black Box" of glass which accommodates the State Archaeological
Museum. Designed by the architects of the State Building Authority Mecklenburg-Western Pomerania, the
monolithic, shining black cube exhibits neither windows nor any other visual differentiation apart from its
entrance side.
The building was constructed as a reinforced concrete construction with external walls of lightweight
bricks, in front of which was installed a ventilated rainscreen cladding StoVentec Glass facade consisting
of black enamelled glass. The contrast between the Black Box and the brick masonry could not be greater;
at the same time, though, it combines the past and present to form an ensemble.
Exciting contrast: the masonry walls
meet a glass "Black Box".

MP09, Graz
The capital city of Styria, Graz, is not exactly famous for wild jungle animals. But there is a "Black Panther"
at the Liebenauer Tangente. Anyway, this is what the MP09, the office building of an optics company, is
known as by the natives and staff. And, in fact, its mysterious dark gloss makes the building, resting on
its bases with the spectacular protruding bow, look like a panther ready to pounce. The Graz-based
GSarchitects designed an architectural sculpture that is intentionally conspicuous in its urban environment.
In the words of GSarchitects, "Architecture can be anything: functional, pragmatic, poetic, urban, or
aesthetic. For us, the MP09 does not only have a bit of all these features - it's got it all.”
The dynamic quality of the architecture is enhanced by the use of StoVentec Glass: the black glass panels
reflect their environment, which is continuously in motion. People, traffic, clouds, the course of the sun
– the building itself is a platform for a continuously changing drama.

Reutlingen is regarded as the "Gate to the Swabian Jura". The work of the local company Manz AG
constitutes a gate to future-oriented energies: Manz builds machines with which solar cells are produced.
What could be more natural than integrating photovoltaic into the architecture of the new customer
centre? Hence the visually striking stair tower was fitted with StoVentec Photovoltaic solar modules.
Across a surface of 160 m2, solar energy is converted into electricity – simultaneously, a contribution is
made to environmental protection and is evidence of a corporate mission. Developed in cooperation with
Würth Solar, the facade system is not only distinguished by its energy-technical but also by its aesthetic
qualities: the dark shining pinstripe-patterned modules form a visual contrast to the shining whiteness
of the rest of the facade. Designed by the Hank + Hirth architects office, the customer centre forms the
focal point of a whole ensemble of production and office premises and provides space for offices,
conference rooms, a canteen, and a
spacious production hall.

A combination of these requirements is demonstrated by the clinic in Hoyerswerda, Saxony: the extension
and refurbishment of the building complex includes the new construction of an examination and
treatment centre over six levels that is out of the ordinary. It was implemented with StoVentec Glass.
Sun protection glass was used both for the flush-mounted windows in the front and the glass facade,
achieving an even surface. The glass facade tilts forward by approx. 4 degrees towards the top of the
building, providing an unusual picture for spectators. The lateral, downward tapering closures have been
accomplished using trapezium-shaped glass panels. The highlight here is the rectangular "glass body" on
the roof of the building: not flush but consciously arranged in an offset pattern, it protrudes prominently
into the air.

Where worlds meet:
Cultural Centre, Schönsee
Schönsee is a quiet place not far from the German-Czech border, where a project has been implemented
that is committed to the meeting of different cultures. The "Centrum Bavaria Bohemia" is accommodated
in the former community brewery: until the 1950s, the families in the town used to brew their own beer
in the building, which was built in the 17th century. Today it is not just different cultures meeting there,
but also different worlds of materials: the printed panels of StoVentec G have been mounted to the
original stone walls.
The Brückner & Brückner architects's office, which was commissioned with the refurbishment, added
another storey to the eastern wing by integrating a reinforced concrete core into the old walls on which
the glass facade could be mounted. The 120 x 21 cm sized panels pick up the patchwork structure of the
old masonry: they were arranged in a stretcher bond and a photo of horizontally layered glass panels
was printed onto them. A double abstraction that blurs the border between material and construction.
Architecture as a sign of encounter:
the glass facade picks up the detailed
structure of the masonry.
