The Window as a “Solar Panel”: Light Transmittance & Solar Factor G

With this article, we cover two very important aspects of glazings: light transmission and the solar heat gain coefficient. These parameters are extremely important for performing buildings and passive houses, however they are often overlooked by both designers and window manufacturers.

Thermal transmittance of glass: the Ug value

Insulated glass units, IGU for short, have been around for a long time. These elements are of primary importance for the energy balance of highly performing buildings and passive houses: that is why we dedicate this article to the thermal transmittance of insulated glass.
