FAQs about Solar glass transmittance and unit price

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.

Does solarbronze® glass provide spectrally selective light transmittance (VLT)?

In a one-inch insulating glass unit (IGU), Solarbronze® glass provides excellent visual light transmittance (VLT). To achieve spectrally selective glass, as recommended by the U.S. Department of Energy, team Solarbronze® glass with Solarban® 60 solar control low‑e glass to earn a light‑to‑solar gain (LSG) ratio of 1.25 or better.

What is the unit of measurement for thermal transmittance?

The unit of measurement for thermal transmittance is W/m 2 K, Watts per square meter per Kelvin. The light transmittance (TL) expresses the amount of light transmitted through the glass. It is the percentage of light, visible to our eyes, that the glass of a fixture allows to filter into the internal environment.

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.
