Sihlpost, Zurich, Switzerland.
A multi-story window facade covering a total area
of 6.500 m2 (65.000 sqft) characterizes the
«Haus Lagerstrasse». Designed by Gigon/Guyer
architects, the glass facade elements feature
SEFAR® Architecture VISION Fabric with open
areas between 55 % and 70 %, reducing solar
glare and improving the working environment.
Glass opens up the view and creates a horizon.
It’s inviting. It reflects the quality standards of
architects, glass manufacturers, facade planners,
metal and facade engineers, and brings transpar-
ency to a building. Incorporating glass into a
construction is always a challenge but with SEFAR®
Architecture VISION glass presents the perfect
combination of design and function.
With fabrics by Sefar Glass makes construction easy

It is unusual for a building material to bring so
much openness to architecture. Glass in itself is
an excellent construction material. Glass in combi-
nation with fabric propels ambitious architects to
the very forefront.
Belaruskaya Kalijnaya Kompaniya (BKK),
Minsk, Belarus. Resembling the redsylvinite
crystal, the facade specifications for this corporate
building designed by architects Varabyeu Partners
in Minsk, combine maximum application of color,
light, and glass. Imparting both color and light
simultaneously, the single-side printed SEFAR®
Architecture VISION PR 260/55 red fabric has an
open area of 55 %, allowing for unaltered views
from the interior and no color «read-through» into
the atrium.
We go to the heart of the matter:The combination of glass and crystal-clear aspirations
SEFAR® Architecture VISION is a range of high-precision fabrics made from synthetic black fibers. In a complex process, fab-ric made from thread sizes of 140 or 260 microns is metal-coated on one side. The range consists of Aluminum, PR Copper, and PR Gold. By means of digital printing, the coated fabric sides can be further individualized with simple lettering or even designs covering a large area. Fabrics coat ed on both sides can have two completely different printed designs without any
read-through on the reverse side. In this way, glass gains color – and a designer sig-nature on the exterior and preserves views and reduces glare in the interior. And there are a multitude of extremely attractive design possibilities for glass and the skillful interplay with light. When used in facade elements, SEFAR® Architecture VISION Fabric is laminated in glass. With two fabric layers, moiré patterns or hand- crumpled fabrics enable the creation of a truly unique design.
Single-side printed SEFAR® Architecture VISION Fabric
emphasizes the sculptural appearance externally in
a clever way. The external view from inside remains
almost clear and unaltered because of the special
one-way visual effect of the fabric.

VISION Fabric creates
interplay with light and
environment.
Würth, Rorschach, Switzerland. Around 1750 laminated glass panels form the extensive, graceful,
and rhythmic shell (approx. 7.800m2) of this company building designed by architects Gigon/Guyer.
The single-sided, aluminum-coated SEFAR® Architecture Vision Fabric AL 140/70 combines optical and
energy-saving functions perfectly.
Free space for architectural form language
Architects and clients demand new de-sign possibilities. They desire to integrate existing surroundings and the landscape. The solution is a combination of glass with fabric. Glass conveys both modernity and lightness of touch. Glass with integrated SEFAR® Architecture VISION Fabric alter-nates between transparency and reflection, and mirrors the beauty of its location and environment.
Minute by minute, the Sefar fabric glass skin alters its appearance, reflecting sky or water and changing over the course of the day and the seasons. But glass in combina-tion with Sefar fabric can do even more.
It gives the environment a completely new dynamic and changes the face of its sur-roundings, creating its own identity

Metal-coated fabrics lend facades
a special aesthetic quality.
Fashion Group Headquarters, Madrid, Spain.
The alternation between clear glass and glass
finished with SEFAR® Architecture VISION Fabric
lends a third dimension to the facade. The high
reflective properties prescribed by Rafael de La-Hoz
Architects are achieved by additional calendering
of the fabric.
Metal-coated fabric
Aluminum coated fabric can be printed in an additional process, e.g., with a logo
or any two-dimensional design. In this way, metal can be given an individual and
more emotional component.
Glass is hardnessFabric adds softness
Various fabric types and different metal coatings provide scope for creative plan-ning - on facades and parapets, with blinds, partitions, and wall coverings. One thing is certain: The unique interaction with natu-ral and artificial light. This imparts an at-mosphere to interior spaces. And exterior surfaces seem to absorb their surround-ings. With the addition of difference types of glass and fabric, the possibilities for re-markable, aesthetic design possibilities are greater still.
Virtually every design and pattern is pos-sible, even with CI-compliant houses and special colors. Combinations with struc-tured glass or float and mirror glass with
SEFAR® Architecture VISION Fabrics are surprisingly effective. Metalized and used in conjunction with glass, technical pre-cision fabrics can be laminated between single panes to alert free-flying birds and provide the building with climatic, acoustic, and optical functions in equal measure. The result is a slender, rhythmic glass curtain which offers protection from glare, noise, heat radiation, and over-cooling.
Curved glass
Curved glass is a clever variation, e.g.,
in stores or trade fair buildings, or for
bathing and spa areas.

SBB Office Building, Bern Wankdorf,
Switzerland. For the facade, Lussi+Halter Partner
AG opted for a visually and functionally modern
design. The story-high glass operable fins SEFAR®
Architecture VISION Fabrics in AL, CR, PR Gold, PR
Copper, and PR Pearl orientate themselves towards
the sun to provide glare protection, reduced solar
gain, and shade.
Facade designers, planners, and architects determine the individual external appear-ance of a building through the skillful com-bination of glass, window sashes, and pillars, as well as operable glass fins and/or facade elements. Glass with integrated SEFAR® Architecture VISION Fabric provides an increased range of safety and functional characteristics, thereby increasing the advantages of glass in application.The spe-cial finish using SentryGlas® Foil for facade windows meets the very highest safety standards.
The percentage of open areas in a chosen fabric depends on how much visual trans-parency is desirable from the outside and to what extent the glass needs to provide protection from glare and thermal reduc-tion. The reflective properties offered by the metal coating reduces heat input considerably and makes a correspondingly valuable contribution to the environment and to associated energy costs. Additionally, independent studies have also shown that the risk of bird strikes on glass facades with integrated SEFAR® Architecture VISION Fabric is significantly reduced.
This unique combination gives a building
personality and a new radiance.
Thanks to the one-way vision effect, external views
from inside the building and natural light quality are
virtually unrestricted.

Safe, comfortable, and resource-friendly
Glare and sun protection
SEFAR® Architecture VISION softens focus – simultaneously re-flecting sunlight, reducing glare, and lowering heat absorption, thereby saving energy and protecting the environment
One-way vision effect – privacy and external views
The one-way vision effect means the assurance of internal privacy yet, depending on the type of fabric chosen, a virtually unrestricted view of the outside world, while reducing glare and possible the need for a interior shading system.
Energetics
The higher reflectance of the metal coat-ing reduces heat transfer inwards during the summer, reducing demand on the air-conditioning system,thereby helping to save energy and reducing a building’s energy cost.
Safety
In conjunction with a SentryGlas® ionoplast interlayer, functional windows meet not only exacting architectonic requirements but also the very highest safety standards.
Bird protection
A study by the Swiss Ornithological In-stitute near Lucerne has shown that bird strikes on glass facades with integrated SEFAR® Architecture VISION Fabric can be greatly reduced.
With Sefar fabric, glass gains additional value and it looks great.

Designs
From color patterns to brand-ing, the fabric can be custom printed and individualized, with no read-through to the other side of the glass. If the fabric is coated on both sides, it can have different printed designs on each side without any read-through tothe other side.
Special colors
Colors are as individual as construction projects, businesses, and people. Hardly any construction component conveys as much emotion as color.
For this reason, it is crucial to Sefar that every custom color is faithfully reproduced in its final application.
The range:Anything but a standard range
Product labeling
4 fabrics and 1 metal coating (single and/or double-sided available) together with 2 print colors form the 16 products in the comprehensive basic range. Product label-ing provides information on the coating metal, thread thickness in microns (µm), and the percentage of open area in a fab-ric. If a fabric has also been printed, the product label begins with «PR».
Glass and Color: You have a free hand.
The standard range includes fabrics with different thread sizes. The open area or apertures – is formed depending on the fabric weave type. The percentage of the open area determines the one-way vision effect, controlling the degree of vision protection from the outside inwards and influences the almost neutral external view from within the building.
In this way, planners decide how much light, privacy, and unobstructed views they want to have according to their choice of fabric and weave. With a choice of AL, PR Gold, and PR Copper, exciting new design possibilities are created – both for interiors and exteriors.

Glass alone would be insufficient
SEFAR® Architecture VISION Fabrics
empowers glass with optically and
functional properties.
Glass on its own allows almost unrestricted sun and light into a building. The total energy trans-mittance (g-value) according to DIN EN 410 gives a critical indi-cation of the proportion of in-cident solar radiation entering an interior space. The lower the g-value, the better the protecti-on from summer heat. SEFAR® Architecture VISION Fabric plays a crucial role in reducing solar gain into a building.
The fabric’s open area determi-nes the degree of energy trans-mission and transparency. With the denser meshes in particular, a significant reduction in light and heat transmission can be
achieved. When weaving syn-thetic filaments, warp threads are respectively raised or lo-wered and the weft threads in-between shot or drawn. In this way, it is possible to crea-te meshes with an open area from 25 % – 55%. The metal coating is also instrumental in the reduction of energy trans-mission.
The SEFAR® Architecture VISION Fabric reflect the heat radiati-on up to 45 % and additionally absorb a large part of the ra-diation itself. Therefore the fabric blocks up to 70 % of the overall heat radiation.
