Technical FAQs 4

What is the difference between Solar Factor and shading coefficient?

Solar Factor or Total Solar Energy Transmittance or g-value (g%) is the total solar radiation transmitted by the glass. Shading Coefficient (sc) is Solar Factor divided by 0.87. It is a measure of the solar heat gain referenced to 3 mm clear glass which has the designated value of 1.00.

What is visible light transmittance?

Visible Light Transmittance (Tv, %) is the percentage of incident light in the wavelength range of 380 nm to 780 nm that is transmitted by the glass. Visible Light Outdoors/Indoors (Re out/in, %) is the percentage of incident solar energy directly reflected by the glass.

Which material has the highest spectral transmittance of solar radiation?

This study analyse spectral transmission of solar radiation of glass and plastics. The 8 h transmittances are higher than at 12 h and are higher in winter than summer. Methacrylate and smoked glass have the highest transmittance in UV, VIS and NIR ranges. Polycarbonate has the lowest transmittance in UV, VIS and NIR ranges.

What is solar energy direct transmittance (Te)?

Solar Energy Direct Transmittance (Te, %) is the percentage of incident solar energy in the wavelength range of 300 nm to 2500 nm that is directly transmitted by the glass. Solar Direct Reflectance Outdoors/Indoors (Re out/in, %) is the percentage of incident solar energy directly reflected by the glass.
