SheetOPTIX IRB - IR Blocking Acrylic

OPTIX IRB is an infrared blocking acrylic sheet that reflects solar radiation, while allowing a high level of natural light. The IR-blocking additive is in the polymer and allows OPTIX IRB to deliver exceptional IR blocking along with impact resistance and weatherability. The result: interiors benefit from natural sunlight without the heat gain. Ideal for skylights, covered walkways and conservatories.

  • Thickness 0.0” – 0.0”
  • Width 0.0” – 0.0”
  • Length 0.0” – 0.0”
