Gonzen by Alfredo Häberli has a sophisticated woollen expression, reminiscent of fine tailoring. It offers a semi-open view outside and gives warm atmosphere to the room. Colours range from neutrals to warm and indigo tones.

LightFastness {{site.selectedConfiguration.lightFastness}}
ISO 105-B02
Lightfastness relates to the ability of a textile to retain its colour under light. When testing for lightfastness, samples are exposed to artificial daylight for a specified period.
The evaluation scale ranges from 1 (worst) to 8 (best). An increase of one point corresponds to a doubling of the lightfastness, i.e. the same fading takes twice as long.

Visual light transmission {{site.selectedConfiguration.lightTransmission}}%
Light transmittance indicates the percentage of the visible light penetrating the textile. Densely woven textiles in dark colours usually have a lower light transmittance, whereas loosely woven fabrics in light colours allow more light to pass through.

Fire tests NFPA 701 • EN 13 773 class 1 • DIN 4102 B1 • NF P 92 507 M1 • BS 5867 part 2 type B • IMO FTP Code 2010 Part 7
Flame retardant performance depends on the type of foam used. There are differing requirements concerning the flame-retardancy of textiles dependent on the area of application, country or even region. Our textiles pass the majority of international standards and are also tested for a selection of regional requirements.

Glare control rating {{site.selectedConfiguration.glareControlRating}}
Optical properties according to EN14500: 2008
-
Solar reflection {{site.selectedConfiguration.solarReflection}}%
Optical properties according to EN14500: 2008
The percentage of solar radiation reflected by the textile.
-
Solar transmission {{site.selectedConfiguration.solarTransmissionTs}}%
Optical properties according to EN14500: 2008
The percentage of solar radiation penetrating through the textile.
-
Solar absorption {{site.selectedConfiguration.solarAbsorption}}%
Optical properties according to EN14500: 2008
The percentage of solar radiation absorbed by the textile.
-
Openness factor {{site.selectedConfiguration.opennessFactor}}%
The percentage of openings in the textile.
-
g-value/ Solar Heat Gain Coefficient {{site.selectedConfiguration.solarHeatGainThroughTotalFenestration}}%
Results are based on reference glazing D according to EN1450: 2005.
The percentage of solar energy that penetrates through glazing and textile. A low value means good thermal performance.
-
Total visual light transmission - based on reference glazing G and according to EN14501:2021 {{site.selectedConfiguration.visualLightTransmissionGlazingTv}}%
Results are based on reference glazing G acc. to EN14501: 2021.
The percentage of visible light penetrating through the textile. If too much visible light is transmitted into a room, it creates brightness and glare problems. For rooms with PC workstations, the maximum recommended light transmission depends on the direction in which the window faces:
North facades: 15–20% light transmission
West and east facades: 2–6% light transmission
South facades: 0–5% light transmission
This is specified by the EU directive 90/270 and ISO 9241. -
U-value - based on reference glazing G and according to EN14501:2021 {{site.selectedConfiguration.uValueWM2K}}
Results are based on reference glazing G acc. to EN14501: 2021.
U-value describes the thermal heat loss (or gain) through a fenestration. The U-value reflects the energy flow through glass and fabric when there is a temperature difference between outside and inside, and is the insulating property. The lower the value, the better the textile's thermal heat insulation properties.
