* Visible Light Transmittance percentages are based on viewing area not overall unit.
Ultraviolet (UV) light block is the percentage amount of UV transmittance blocked from the interior. U-Factor is the amount of heat that transfers through the window. Solar Heat Gain Coefficient (SHGC) is the amount of solar radiation that transfers through the window. For U-Factor and SHGC, lower numbers equate to higher energy efficiency.
