DESIREE SUN DELIGHT FOR ENERGY-SAVING GLARE AND PRIVACY PROTECTION- Nisha Designs

We have equipped our classic Desiree Chintz with a metallized backing, thus transforming it into an energy-saving sheer with a glare and privacy function that provides sun protection similar to a sunscreen. The metallized backing reflects the sun’s rays and thus prevents the room from heating up too much. This additional feature gives the backing a silver metallic shimmer without shining through to the front. The matt fabric side faces the room and creates a cosy, homely character. Desiree Sun not only protects against the sun, but can also serve as a privacy screen which at the same time – due to its slight transparency – still gives the room enough light. Particularly noteworthy is the soft drape, which is not present in classic aluminium-vaporized articles.to the article

TECHNICAL VALUES

Extensive tests resulted in the following photometric values:

  • Light transmission: 25% (percentage of total visible sunlight passing through the curtain)
  • Light reflection: 45 %
  • Light absorption: 30 % (The amount of radiant energy absorbed by the curtain and converted into heat)
  • UV transmission: 25 %.

Comprehensive tests resulted in the following solar technical values:

  • Solar transmission: 26 % (energy penetrating the fabric / the smaller the better)
  • Solar reflection: 46 % (energy reflected from the back of the fabric / the bigger the better)
  • Solar absorption: 28 % (energy absorbed by the material and converted into heat / the smaller the better)

g-value: 0.42 (total energy transmittance: energy input through the blind; the lower the g-value, the less energy passes through the blind and the lower the temperature behind it)

Fc value: 0.72 (reduction factor of a sun protection device, the smaller the better)

Although this product is similar in function to our DELITHERM products, it is a completely different article in production and in handling. As Desiree Sun has no metalized yarn but is metalized only on the backside, the article looks more homely and offers a larger variety of colours. Special attention must therefore be paid to the processing instructions.


Advantages of energy-saving glare and privacy protection:

  • Glare protection
  • improves the thermal room comfort
  • protects against strong heat radiation and UV radiation
  • reduces the intensity of air conditioning systems (reduction of CO2 emissions)
  • provides for more comfortable viewing at the monitor workstation
  • daylight-permeable
  • respects the privacy
  • is permanently flame-retardant
  • little sewing effort
