About how much would this specific piece have cost?

This door (are there two?) and window "spread"?

Hi Joseph, there are two single doors here flanking a 4-lite fixed window. Double doors (French doors) are also available. Door leaf widths can be up to around 40" each depending on muntin bar configuration and which product range chosen. In regard cost, if based in US I would need to direct you to your local Crittall rep. Let me know what State you are in and I can give you detail. Thanks for your interest!

That would be great. I love your windows. I am in Utah. Salt Lake City.

Joseph, I am in San Francisco, and can help you with the cost and process issues, please give me a call to discuss.

Hi. I am looking to replace my leaded glass windows and doors with bronze. I am concerned as to R value or insulation and also the cost. My home is in CT. USA

The R value in windows is typically listed as the U value and our is going to range from 3.9 to .6 depending on the type and configuration which is consistent with a non-thermally broken window. This is much better than what you would be getting out of old leaded glass windows, but typically not what is required for cold climates. I hope this helps!

Do you know price difference between windows. I mean, are your windows double the cost of new energy eficient divided light windows?? Or comparable?

I don't know what exact windows you are looking at, but our windows are about the same price as steel windows, which are about two and a half times the price of wood and about four times the price of vinyl . This is all very general pricing and varies on what brands you are comparing, but I hope it gives you a general idea. It is like comparing a luxury car with a fuel saving one :)
