Halloween was over in October but yet it is the first post 2 months later.

You will have to order new Insulated Glass without grids. I'd try and find out who made the windows. You might find it better all the way around to just order new sashes or to just buy new windows depending on what condition your existing windos are in.

To worthy about the above comment Chat GPT--the all-knowing arbiter on all matters on earth, the universe and everything-- is surprisingly neutral on the subject WFT? Anyway, about the glass I would have had them glazed with a single piece of black Lexan As these would not require any R-value But, since you already have them Tint the windows Or, a more permanent solution in case the tint peels off over time, whether it be on the outside, or even worse, on the inside where you can't get at it Put thin piece of black Lexan over the glass, and clear silicone them in place For the haters who posted , no fake dormers with windows This is what is called Aesthetics, Curb Appeal This is no different, than people putting on Fake non-operating 18" shutters screwed to a wall, on the side of a 8 foot window Or, Fake window grills over a clear sheet of glass Or, Fake Shaker style white cabinets that are pressed MDF Or, Fake colonial doors , that are pressed Masonite Or, Fake cultured marble Or, a Fake wood floor, that is pure vinyl, with a plastic veneer over it The list goes on and on Also, the Fake hood scoop and air intakes on my 4Runner TRD Pro, Lol I attached a picture of a house I am building this Spring The whole huge front dormer does nothing and it also has a window to nowhere, that will be glazed with black Lexan I edited the picture of the house in paint, not very well though But you get the point of how it would not look the same without it, or the bump out window Also the bump out window on the left side of the front of the house is in the garage and serves no purpose either Except for aesthetics, and makes the house look bigger than it is As it is a triple garage entered from the side Look at the windows, they look black The window tint can be installed on the outside of the glass as well So you wouldn't have to take the windows out, if they are already installed Here is one of many places on the Internet that do it, and no, I don't work for this window tint company, all kinds of places that do this, like places that tint car windows near you https://www.rcwindowfilms.com/exterior-window-films/ Edit: I just noticed I am replying to a 8 year post They should archive these at some point So, you probably have already solved the issue in 8 years, Lol What did you do?
