Air 4 is a classic curtain designed by Erik Ole Jørgensen.
Crafted from Trevira CS, Air 4 is plain woven, offering a matte structure that evokes a natural look and feel. Its light construction results in a soft drape, creating a delicate layer of translucent colour between the interior and exterior. The palette supports the airy nature of the textile, with 21 nuances built up in colour groups. Each hue varies in intensity, from sky blue to violet, mint to dusty green, and from wax yellow to apricot. These gradients sit alongside a versatile range of both warm and cold neutral tones. Air 4 is fire retardant and has superior lightfastness, making it an ideal choice for contract environments as well as private homes.

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.
-
Absorption (100 mm) 0.05/Unclassified (Absorption flat) 0.10/Unclassfied (Absorption folded)
EN ISO 354
Acoustic absorption is indicated as αw-value which approximately corresponds to the percentage of sound absorbed. For instance, an αw-value of 0,4 translates into 40% absorption of sound. Acoustic absorption of a textile is measured in its flat and draped state.
-
Airflow <10 Pa s/m
EN ISO 9053-1
Airflow resistance influences the sound absorbing qualities of a textile. Typically, the denser the construction of the textile, the higher the value.

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.

Regular cleaning is important in order to keep the curtain textile looking its best and to prolong its life. Dust and dirt wear down the textile and also reduce its fire-retardant properties.

Regular care
If possible, we recommend washing curtains once a year. If used heavily, a more frequent cleaning may be appropriate. All curtain fabrics by Kvadrat and Sahco are supplied with a care label. We recommend the use of detergent without optical bleach for all items in which, according to care instructions, washing is possible. Please take into account a possible shrinkage between 1–4 %. It is always possible to wash at a lower temperature that the one specified for light soiling. Please contact a professional dry cleaner if dry cleaning is the only option for maintenance. A professional dry cleaner may also assist in working out maintenance schedules which ensure that the fabrics are maintained properly so that a good indoor climate and maximum duration of the curtains are achieved.
