Light

High-tech fabrics for panels, vertical and roller blinds that efficiently reflect heat and absorb light in buildings with large areas of glass panelling.

The technology has been developed by the division of Svensson that manufactures climate screens for professional greenhouse cultivation. Svensson has utilised this technology and created exciting, contemporary designs to produce a revolutionary new product to save energy and improve the work environment.

Beneficial properties of the screens:

  • Cost-efficient and climate-smart solutions for different heat- and light control needs.
  • The highest possible quality and function.
  • Fabrics in subtle base colours or with innovative tones and decorative patterns.

Improve comfort and the working environment

Our solar control collection is used to improve thermal and visual comfort and provides protection from glare and acts as a sunblind, while also preventing solar radiation being turned into heat.

Thermal comfort

Our bodies need to be in thermal balance so that we do not feel too hot or too cold. It is easy to believe that only the air temperature has an effect, but there are actually six factors which influence the concept of thermal comfort:

  • Air temperature
  • Airspeed
  • Air humidity
  • Radiation temperature
  • Activity level
  • Clothing

Instead of talking about air temperature, we usually use the term "operative temperature", i.e. the perceived temperature. A human may not perceive the temperature in a room to be 22 degrees just because the air temperature in the room is 22 degrees. How hot the objects in the surrounding area are (radiation temperature) has a major effect on the operative temperature. The perceived temperature is basically the average of the air temperature and radiation temperature from surrounding objects, such as windows which is hot (in summer) or cold (in winter).

In the international standard ISO 7730, recommendations are provided for the thermal indoor climate. Among other things, it is stated that the operative temperature for normal office work in winter should be 22 °C ±2 °C. If it is hotter or colder than this, surveys show that work performance is adversely affected.

Visual comfort

Visual comfort involves not being blinded by glare from direct solar radiation or its reflections, but it also involves creating a pleasant climate for the eye by not exposing it to excessively great luminance differences (contrasts) at the same time.

The eye has no trouble handling the high light intensity, for example; if we go outside on a summer's day, it only takes a few seconds for our eyes to adjust to the brighter conditions. But on the other hand, the eye has a lot of trouble handling major contrasts at the same time.

To ensure good visual comfort at a workplace, we refer to the rule of thumb which is the 1:3:10 ratio. This means that visual objects (e.g. computers, paper), the surrounding field and the periphery (e.g. windows) should be in a luminance ratio of 1:3:10 to one another.

That is to say, the luminance (light intensity) in the surrounding field of view must not exceed three times the luminance of the visual object. Nor must objects within the periphery (such as a window) exceed ten times the luminance of the visual object. The same rule applies the other way round, too: 10:3:1.

Benefits of using Svensson solar control

  • Flame retardant
  • Bearing the Oeko-Tex label – eco-friendly
  • Enhances visual comfort in the workplace
  • Keeps room temperature down in summer, thereby reducing the need for artificial cooling
  • Makes sure that the heat stays in the room in winter, thereby reducing the need for heating
  • Reduced energy costs
  • Greater comfort enhances work performance

Why use internal sunblinds?

Unlike external sun blinds, our products can be used no matter what the weather. A flexible system permits the user to make adaptations according to requirements. Further benefits are:

  • Lighter and cheaper to install than external sun blinds
  • Easier to maintain – and hence cheaper
  • Longer service life – no wear and tear due to the wind and weather
  • Can be used in all buildings irrespective of façade type
  • Can be used in both summer and winter as the system can be adjusted according to the height of the sun

Possible installations

There are a number of installation options for of our Solar control collection.

  • Slats/ Vertical blinds
  • Roller blinds
  • Panel curtains
