Product description

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.

Widths up to 280 cm are available from stock for mock-ups and sampling.

Wider widths can also be produced on request and are available with a minimum order quantity (MOQ).

Performance
  • 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.

  • Exterior LightFastness 7-8
  • 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 GB 8624 B1 • BS 5867 part 2 type B • EN 13 773 class 1 • EN 13501-1, B-s1, d0 • DIN 4102 B1 • NFPA 701

    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: 2021

  • Solar reflection {{site.selectedConfiguration.solarReflection}}%

    Optical properties according to EN14500: 2021

    The percentage of solar radiation reflected by the textile.

  • Solar transmission {{site.selectedConfiguration.solarTransmissionTs}}%

    Optical properties according to EN14500: 2021

    The percentage of solar radiation penetrating through the textile.

  • Solar absorption {{site.selectedConfiguration.solarAbsorption}}%

    Optical properties according to EN14500: 2021

    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 G according to EN14501: 2021.

    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. 

  • Fire resistant

Discover our coherent roller blind textile family

The Retta family brings together three closely related roller blind textiles: Retta, Silvretta and Retta Blockout. Designed to work in dialogue, they enable architects and designers to maintain a consistent aesthetic while adjusting performance to different requirements – from soft daylight filtration and visual comfort to improved thermal performance and high levels of light exclusion.

All three textiles are developed from the same base material and share a common expression. Each offers its own functional characteristics, making it easier to apply a unified shading solution across different spaces within the same project, without compromising on performance.

Complete your roller blind solution

Pair this textile with a roller blind system that meets the requirements of your project. Whether you are looking for seamless integration, exposed expression or flexible installation options, our range of roller blind systems offers the ideal solution for any space.

All our shading solutions ensure smooth operation, a precise fit, and longevity. Explore the options to specify a fully integrated, high-performance shading solution.
