Sufficient sunlight is essential for humans. It brings vitality, motivation, health – well-being. The change between light and dark determines our day/night rhythm, that is, the fine-tuning of our inner biological clock.
Though conventional glazing of skylights and light domes allows light into buildings, along with “white” light it also permits the invisible heat radiation to pass. What is needed is an intelligent shading system that filters out solar heat radiation while allowing the illuminating portion of sunlight to pass through. EMD Performance Materials’ functional pigments from the Iriotec® 9000 series offer exactly these advantages.
Iriotec® 9000 lets sunlight into buildings and rejects heat
Heat-reflecting, translucent pigments of the Iriotec® 9000 series provide transparent shading for glazing as well as blinds. Most of the visible part of sunlight that is essential for human well-being can pass into the residence, building, conservatory or stadium, while the invisible UV light is for the most part absorbed.
However, the multi-talented pigments show their greatest advantages in summer when heat usually accumulates under glass roofs or in conservatories. Iriotec® 9000 pigments reflect the infrared part of sunlight and with it the heat radiation, reducing it by up to 75 percent. Conventional, non-pigmented shading systems always reduce light transmission as well – to the detriment of the room’s brightness.
EMD Performance Materials pigments of the Iriotec® 9000 series therefore offer a threefold advantage:
- They let sunshine in and save costs for artificial light.
- They make additional shading superfluous.
- They enable considerable savings in building cooling when the sun shines with all its power.
