7. Low-emissivity glazing applications

There are a wide variety of applications for low-emissivity glazing, thanks to its high light transmission and low resistance per square.

The performance of these films can be compared with each other by a figure of merit which can be, for example, as defined by Haacke [7] : $\Phi =T^{10}/R_{\square }$

where $R_{\square }$ is resistance per square and T is integrated light transmission in the visible range. Thus, for a given material, merit is only a function of thickness.
