Koolblack screen blind fabric technology, Launched by Mermet into the Australain market in 2014, provides the ultimate in view through, glare control and energy savings. A combination that has not been available before in dark colored screen blind fabrics.

Traditionally dark coloured screen blinds have been the colour of choice for Interior Designers who’s main objective is to control glare. This is particularly useful in an office situation where the control of glare is paramount so that staff using computer screens, mobile phones and tablets can enjoy a maximum level of comfort whilst still allowing natural light into the room. Unfortunately these fabrics also retain heat such as in the thermal image below.


This in turn results in warmer rooms and higher air conditioning costs pushing up the cost of maintaining the office. When multiplies over a multi-story building these costs can become significant. The same goes for that west facing room in your home too!

Koolblack technology helps solve this dilemma by patented technology within the yarn of the fabric that reflects Near Infrared (NIR) energy reducing the overall temperature of the fabric in direct sunlight no matter how dark the fabric.

How does it work? In a joint partnership with German chemical giant BASF, Mermet have developed Patented technology withing the yarn of the fabric that actively reflects Near Infrared energy independent of the colour.

Additional benefits include.

  • Can be matched visually with standard Mermet screen on the windows that are not readily exposed to the sun, such as a southern wall. you only really need the Koolblack on the windows exposed to the sun.
  • Improved control of heat, particularly in summer whilst still maintaining a crisp clear view to the outside.
  • Yarn features a fiberglass core for maximum strength and minimal fabric movement in heat and cold.
