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.

We continue our series of articles on thermal efficiency of windows, describing the glass edge thermal bridge.

As far as thermal bridges go, this one is inevitable, and it represents the weakest point of a well designed thermal envelope. It needs to be analyzed carefully, in order to prevent condensation (or ice) to form on the edge of the glass, discomfort, and an overall drop in the performance of the window/door.

After covering thermal transmittance U and resistance R of opaque assemblies, and insulated glass, we now cover one of the most critical areas of the thermal envelope: window frames.

Good windows are the cornerstone of a performing building for both comfort and energy efficiency, specially if it is a passive house.
