For performance characteristics of glazing options not listed above, please connect with the manufacturers’ link below to be directed to the specific manufacturer’s performance calculator. These tools are very useful and provide performance characteristics for the specific glazing combinations you choose, including argon and krypton gas filling, single-glazing options, laminates, spandrels and frits, and high-performance solar control products

Terms (as defined in GANA's Glazing Manual):
Visible Light Transmittance The percentage of visible light within the solar spectrum that is transmitted through glass.
Solar Energy Transmittance The percentage of ultraviolet, visible and near infrared energy within the solar spectrum (300 to 2100 nanometeres) that is transmitted through the glass
Visible Light Reflectance The percentage of visible light within the solar spectrum (390 to 770 nanometers) that is reflected from the glass surface.
Solar Energy Reflectance In the solar spectrum, the percentage of solar energy that is reflected from the glass surface.
U-Value A measure of air-to-air heat transmission (loss or gain) due to the thermal conductance and the difference in indoor and outdoor temperatures. As the U-value decreases, so does the amount of heat that is transferred through the glaazing material. The lower the U-Value, the more restrictive the fenestration product is to heat transfer.
Shading Coefficient The ratio of the solar heat gain through a specific glass product to the solar heat gain through a lite of 1/8" (3mm) clear glass.
Relative Heat Gain The amount of heat gain through a glass product taking into consideration the effects of solar haeat gain (shading coefficient) and conductive heat gain (U-value). The lower the relative heat gain, the more the glass product restricts heat gain.
Solar Heat Gain Coefficient (SHGC) The ratio of the solar heat gain entering the space area through the fenestration product to the incident solar radiation. Solar heat gain includes directly transmitted solar haeat and absorbed solar radiation, which is then reradiated, conducted, or convected into the space
Light-to-Solar Gain (LSG) The visible transmittance of a glazing system divided by the solar heat gain coefficient (or shading coefficient). This ratio is helpful in selecting glazing products for different climates in terms of those that transmit more heat than light and those that transmit more light than heat.
