The heat flow through a 1m x 1m sample of vacuum glazing has been measured in two independent ways. One measurement method uses a guarded hot box to make a direct determination of overall heat-transmission coefficient under standard test conditions. The other method uses a small-area guarded ho...

I use Window 5.2 to create windows to introduce in TRNBUILD. I make some test and I don't understand why the U value of a glazing change when I change the order of the layers. It is obvious that the radiation coefficients change with the order of the layer but the U value that, fo...

Although a U value as low as 0.7 sounds very impressive, the additional energy saved is small. The key benefits are really to do with comfort. If the walls, roof and floor of a house are insulated, and the glazing ignored then there is a risk of cold spots surrounding the windows at ...
What is the U-value of a wall? Typical values Solidbrick wall: 2 W/(m²K)Cavity wall with no insulation: 1.5 W/(m²K). Insulated wall: 0.18 W/(m²K). Single glazing: 4.8 to 5.8 W/(m²K). How do you calculate the U-value of thermal conductivity?
Glasbau Hahn is proud to have made two internationally notable contributions to this 2650-year history of glass with the invention of glass cement before 1930 and suspended glazing in the 1950s. Glasbau Hahn owned in his history over 130 patents. Glass is our passion. ...
