Clearview by Alfredo Häberli offers an intricate woven structure and a sophisticated character. Clearview is Cradle to Cradle certified and a sustainable roller blind textile option. 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.
With the Cradle to Cradle certification, Clearview can contribute to points in globally recognised building sustainability standards such as LEED and BREEAM, helping projects to meet environmental performance benchmarks.
This textile was formerly sold as Niesen. From January 2023 Niesen is renamed to Clearview.

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.

The percentage of solar radiation absorbed by the textile.
The percentage of openings in the textile.
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.
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.
