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.
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.
Colorado: our work ties become permanent
With Mariana currently involved full time with Natural Capitalism Solutions and AE Building Systems, our professional ties with Colorado are now solid. This allows us to have experience in highly efficient buildings on both sides of the Atlantic, with some initial interesting considerations.
