More Windows Adversity

Here are two pair of pictures demonstrating the attenuation the switch in Windows caused:

with the Window Closed

 

signal was “bad” and was even worse on 5gHz WiFi

 

 

Window open with a great signal

open window gave a great signal

 

For certain it is the Low Emissive glass in the new windows. Somewhere in the assembly will be a metallic film intended to triple or quadruple the energy reflectivity compared to plain glass.

A plain glass window is expected th attenuate less than 1 dB where Low-E glass ranges between 33 and 50 dB attenuation.

The phenomena is why WiFi and Cellular signals can often be blocked by mirrors. The metal film causes attenuation.

An unexpected consequence of upgrading Windows!
