A light weave fabric with appropriate visible light transmittance and low absorptance is recommended to allow more sunlight into the classroom, while reducing cooling loads.
In a standard one-inch insulating glass unit with a clear inboard light, Vistacool Caribia produces Visible Light Transmittance (VLT) of 47%--nearly twice the average of other tinted, reflective-coated glass products on the market--together with a Solar Heat Gain Coefficient (SHGC) of 0.34.
Low-E coatings can combine the advantages of a reduced U-factor and SHGC while maintaining high levels of visible light transmittance. These microscopically thin layers of metal or metallic oxide can be designed to filter radiation so as to reflect UV and infrared radiation while transmitting visible wavelengths.

Graphics illustrate common glass-performance terms such as solar-heat-gain coefficient (SHGC), visible light transmittance (VLT), light-to-solar-gain (LSG) ratio and U-value.
The brochure also uses graphics to illustrate terms such as solar-heat-gain coefficient (SHGC), visible light transmittance (VLT), light-to-solar-gain (LSG) ratio and U-value.
The new-design windshields have a better, more reliable anti-ice heating system, higher visible light transmittance and improved precipitation-static drain.
With visible light transmittance (VLT) of 91 percent in a standard 6-millimeter lite, Starphire glass is the clearest, most transparent float glass available.
When paired with Solarban solar control, low-e glasses in a standard 1-inch insulating glass unit (IGU), Suntuitive glass can produce visible light transmittance (VLT) of as much as 60 percent in a clear state and solar-heat-gain coefficients (SHGCs) of as low as 0.11 in a darkened state.
In a standard 1-inch insulating glass unit (IGU), Solarban 60 Optigray glass has visible light transmittance (VLT) of 50 percent and a solar heat gain coefficient (SHGC) of 0.30, which yields a light-to-solar-gain (LSG) ratio of 1.67.
With visible light transmittance (VLT) of 54 percent in a clear 1-inch insulating glass unit (IGU), Solarban 67 glass has a solar heat gain coefficient (SHGC) of 0.29 that is nearly equal to that of triple-silver-coated Solarban 70XL glass and superior to that of double-silver-coated Solarban 60 glass.
Solarban 60 glass has visible light transmittance (VLT) of 70 percent and a solar heat gain coefficient of (SHGC) 0.38 with clear glass in a standard 1-inch insulating glass unit (IGU).
