The out layer glass of a horizontal window panel in our living room cracked (see photo). The horizontal window panel is about 42" wide and 10~12" high on top of a double hung window.
I could not figure out how to remove the window panel. The right side of the photo shows a vertical cap which is little loose but I could not remove it by gently pry it with a small screw driver.
Does anyone know how to install and remove those horizontal panels above double hung windows?
Does anyone know who makes those type of double hung windows with horizontal panels above it?

Thanks in advance.

 

If that is a thermo pane , you can't replace that glass yourself. Your picture is not clear enough to see the details. Send more with clear close ups of the sides and corners.

 

A thin putty knife and hammer are often needed to pry the interior stop over. It snaps into a groove so it takes some effort to pry it over. Start at the end of the piece and take care not to dig into the vinyl or mar the frame as you tap and pry.

The outside of the IGU is held by two-faced tape and this needs to be cut in order to get the glass out. Glazing tools are made to do that... but you might be able to use something like this... https://m.lowes.com/pd/IRWIN-1-Blade...nife/50084018# to cut the tape. Lowe's used to have a Kobalt utility blade in the same shape which fit into a utility knife... it worked well in a pinch because it was thin and flexible. (You have to shove it between the glass and the exterior side of the frame in order to cut the two faced tape.) You can see the blade im talking about in this item photo. https://m.lowes.com/pd/Kobalt-27-Bla...Knife/50111430

Once you get the IGU (double pane insulating glass unit) out, you will measure its exact size and thickness and order another from any city glass shop.

 

Thanks! It worked. I was able to use a larger screw driver to remove the vertical "stop over" (see photo) and the horizontal piece under them to remove the panel.

I had IGU panels made by glass shop and installed them my self before.

I have never handled this type of horizontal window panels before.

 

The piece you need to remove is the one around the glass edge. It could be on the exterior side of the window... cant tell from the pics.

 

I would able to remove the 4 pieces shown on interior side of the window panel, remove the IGU to measure it.

Thanks!

 

Yahoo2003 -- Where are you getting your IGUs made? I'm also in the DC area. I saw you had one post about how the cost of a new window at Lowes was cheaper than one IGU and you were speculating that you could just cannobolize the new window for the IGU. Did you end up doing that and, more importantly, did it work? Thanks for any help.
