Description

Pilkington Mirai™ has been developed to mark the start of the next generation of low carbon glass products to help meet stricter sustainability requirements in the built environments. Achieved using a combination of alternative fuel, high recycled glass content, and green electricity sources, Pilkington Mirai™ offers identical quality, performance, and aesthetics as Pilkington Optifloat™ Clear, but with only half the impact on the environment.


Pilkington Mirai™ can be offered in combination with Pilkington Optitherm™ (high performance low-e and solar control coating) including laminated and acoustic variants and has been designed for both commercial and residential segments.


Features and benefits:

  • 50% less embodied carbon* compared to Pilkington's standard float glass.
  • A low Global Warming Potential (GWP**) less than 5.5 kg CO²e per m²*.
  • Manufactured using a combination of alternative fuel, high recycled glass content, and 100% renewable electricity.
  • Identical neutral aesthetics, exceptional quality, and performance as s Pilkington Optifloat™ Clear, but with only half the impact on the environment.
