Well, I've tried to understand what you've said, but I'm a non-physicist... Do I need to get the temperature difference in a different manner? I have filled the calculator you gave me with the following data: specific heat: 840 J/kg.K thermal expansion: 0.0000059 m/m.K conductivity: 1.05...

Hello, I have looked through various websites, which show single glazing heat losses (U-factor) to be 5.7 W/m^2.K. But when I use thermal conductivity basic formulas, the yielded results are quite different: k of glass is 1.05 W/m.K; L -> glass thickness is 4 mm = 0.004 m; so: U = k/L =...
