Do gas-filled windows block wireless signal?

  1. Wireless broadband was always marginal here (at least one
    mile from the tower, with trees in the line of sight ) and became
    impossible the day the windows were replaced with modern
    "Energy Star" units, double-pane sealed units filled with gas
    (either argon or krypton, I forget which.) I could not be sure of
    the cause, but managed to reach an ISP engineer. One of his
    suggestions was to try the directional wireless modem at an open
    window, i.e. no glass -- which immediately provided a satisfactory
    signal. I have instructions for various tests thus will quantify the
    difference if I can.

    The engineer said he had never heard of either window structure
    (aluminum here with steel magnets that hold the fly screens in place)
    or gas-filled sealed panes obstructing wireless signals. Has anyone else?

    If the windows were touted as "low e" you found your problem. Various
    metal oxide coatings are either in the glass or coating the glass to
    lower the emissivity. Metal is also great for shielding RF.

    "low e" type windows can cause this because they contain serious oxides and other gases and they can produce and artificial shield against the wireless signal so your connection will often drop, it will be very slow or even worst you will won't be able to connect.

    Interesting, what else blocks wifi signals?
    I know microwaves seem to interfere with the wifi but what else??????

    Metal film like solar shield does , anything with metallic content will
    or you can defeat the signal with pure bulk

    Interesting atec77, Conversely is there any way that you can make the
    signal better.
    I have heard a few methods but nothing concrete.

    You need to be specific as to your needs
