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.
