1.       Light transmission compares the percentages of visible spectrum light energy to that of an unglazed opening of the same solar exposure.

2.       Shading co-efficient is the ratio of solar heat gain through a glazing system compared to solar heat through a single lite of DSB (1/8”) sheet glass under the same conditions assuming a solar intensity of 248 Btu/sq. ft.

3.       U-Value is the overall co-efficient of heat transmission or thermal transmittance (air-to-air) in Btu/hour/sq. ft./°F.
