Silvretta by Louise Sigvardt is a woven, yarn-dyed textile made from up to three differently coloured yarns. Despite the complexity of the metallised textile’s innovative, precise weave, it has a rich and very natural expression. The composition of coloured yarns gives a deep and interesting colour appearance both from far and close by. Silvretta has a good view out and delivers control over glare, thereby reducing the need for cooling systems and the associated energy consumption.

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.
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.
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.

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.
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 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.
