HISG (Heat Insulation Solar Glass) features a hollow interlayer design that effectively blocks the conduction of hot and cold air, significantly reducing air conditioning energy consumption. Through semiconductor light-transmitting films and high-efficiency reflective film technology, HISG glass efficiently reflects visible light and infrared light, while also incorporating secondary power generation capabilities. Even in low-light conditions such as early mornings, overcast skies, or smog, HISG glass continues to generate power steadily, while also offering multiple features such as heat insulation, wind resistance, and noise reduction.

HISG (Heat Insulation Solar Glass) can be used in building facades, roof glass, greenhouses, and any structure requiring high heat insulation performance. It not only provides energy-saving benefits but also serves as a BIPV (Building Integrated Photovoltaic) material, helping the construction industry achieve nearly zero carbon reduction. It meets the design requirements of modern green buildings.

HISG (Heat Insulation Solar Glass)

The high-efficiency reflective film reflects visible light and infrared (IR) light while simultaneously generating secondary power,
increasing power generation efficiency by 16%
and enhancing heat insulation by 70%.

HISG (Heat Insulation Solar Glass)

With 10%, 20%, and 50% light transmittance options,
it meets aesthetic design requirements and is suitable for various applications, such as daylighting, glass curtain walls, facade glass, or skylights.

HISG (Heat Insulation Solar Glass)

The hollow interlayer design effectively reduces thermal conductivity (U-value), isolating the conduction or transfer of hot and cold air, and significantly lowering heating and cooling energy consumption.

HISG (Heat Insulation Solar Glass)

The high-efficiency reflective film effectively reflects indoor light,
increasing brightness. By combining power generation with heat insulation, it reduces energy consumption and contributes to achieving nearly zero carbon buildings.
