Breakthrough Materials Science

The Dual-Action Radiative Cooling Physics

Developed in partnership with leading advanced materials laboratories, Gallma combines hollow ceramic micro-spheres and high-reflectance titanium matrixes to achieve what conventional insulation cannot.

01

>95% Solar Spectrum Reflection

Standard roofs absorb sunlight across the ultraviolet, visible, and near-infrared (NIR) spectrums. Gallma's micro-crystalline formula reflects over 95% of direct incoming solar radiation before it can convert into conducted thermal energy.

  • • High Total Solar Reflectance (TSR) verified under ISO standards
  • • UV resistant: Will not yellow, chalk, or degrade over 15+ years
02

Thermal Atmospheric Window Emissivity

Unlike ordinary white paint, Gallma emits heat back through the Earth's "atmospheric transparency window" (8–13 µm wavelength). The atmosphere does not absorb this infrared wavelength, allowing heat to radiate directly into cold outer space (-270°C).

  • • Emits heat even under direct, peak midday sunlight
  • • Enables sub-ambient cooling without mechanical chillers
