The future of efficient building energy use

What Makes a Roof Cool

LuminX IR Xpectra represents a revolutionary step in building energy efficiency. This cutting-edge coating technology offers unparalleled benefits to the building industry. Our mission is to deliver superior insulation performance through a cost-efficient, easy-to-apply wall coating layer. This enables hundreds of thousands of buildings to achieve reduced energy consumption, supporting compliance with stringent energy performance standards and contributing to climate-neutral buildings by 2050.

Beyond wall coatings, LuminX IR Xpectra can also be applied in transparent heating, signature management, printed electronics, and more. LuminX IR Xpectra is set to transform multiple industries.

Our transparent,heat-reflecting spray application improves the U-values of walls by up to 25%with just one application.

Launching at BAU 2025

  • LuminX IR Xpectra– Transparent Heat-Reflecting Coating for Walls

  • Improved U-value of walls by up to 25 %

  • Low emissivity of ε = 0.26

  • Up to 74 % heat radiation reflection

  • High water vapor permeability sd < 0.01 m
