Product description

Clearview by Alfredo Häberli offers an intricate woven structure and a sophisticated character. The highly technical, precise composition emphasizes the outstanding performance of the metallised textile. The construction is engineered to give a particularly perfect view out and the highest level of solar reflectance, offering an excellent balance of visual and thermal comfort. As a result, it provides superior control over thermal comfort while reducing the need for cooling and heating systems and the associated energy consumption. This textile was formerly sold as Niesen. From January 2023 Niesen is renamed to Clearview.

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 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 NFPA 701 • DIN 4102 B1 • UNI 9177 Classe 1 • BS 5867 part 2 type B • EN 13501-1, B-s1, d0 • GB 8624 B1

    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.
