IF DIY:

Basic IGU, clear/ clear, 1/2" thick double insulated but no other options like low e, etc. around $222 & change, shipping included from source above.^^

Check local glass companies that sell commercial (store front) glass. We used a commercial glass place when we replaced sidelights.

If the $450 quote includes install, probably a pretty decent quote, IMO.

The $1200 per quote is insane. At that price, I would remove the bow & replace with whole new windows--eliminate the bow and install 3 ganged casements--fixed glass center and casements on L & R.

Many glaziers in Ohio belong to a union. Contact the Union for a list of local to you glaizers.

the glass company quote and the window repair company quotes were Very different ($1200 vs. $450) but I need to verify what glass thickness, seal type , insulating gas, was quoted. but is there a standard?

A MATT: is a glazier only an installer or are they knowledgeable about options for IGUs?

Youve gotten two local glass companies to come out to price it. Any repair in place with new glass will be significantly cheaper than a full window replacement and will have much more glass (they literally don’t build windows like yours anymore). Are the two quotes detailed and equivalent? Are they highly rated with lots of reviews? One glass company in my town can do this cheaper than their competitors because they have their own production facility for making IGUs so they are cheaper than the guy shipping it in from out of state.

Yes, there are standards. Google is your friend. Glass Standards.

A Mat it appears from Google search that the most important feature is whether the unit meets ASTM standards…….glass thickness varies seal type varies unit thickness varies

Yes, there are a lot of variables--overall thickness of the IGU, argon filled, tint, tempered, laminated, frosted/ privacy, metal color, grids.... I ran the #'s on a very basic unit with aluminum spacer...probably the lowest cost option. Which is likely a same for same replacement for the existing 1982 window.

I heard aluminum spacer is the best. How thick is a very "basic" unit?

I provided that info in my first posting. Did you go to the link that I provided?

ci_lantro 1/2" thick....that glass would be awfully thin with the space between the panes for the Argon.

ci_lantro https://www.onedayglass.com/order-online/ sells glass. I need a seller and an installer. and you did say 1/2" thick double insulated I presume that is the unit thickness....glass would be extremely thin. but thanks

HALLETT & Co. I will ask the glass pane thickness as well as the unit thickness...since there is some issue with caulk compatibility to sealant on window...I will ask if they are aware of that....I will ask the seal type (foam or aluminum) Maybe there is a warranty on the windows and the install (that would be nice) ....I will check if there is an R rating on windows. I know the ASTM standard but in order to get into that I would have to pay $$$$ for testing. I still am stuck on total unit thickness...I will attempt to measure the IGU's installed.

Have you considered replacing with a large standard window? My in-laws had a bay window like yours and when it was necessary to replace they installed a standard window. They like it so much better.

Look for direct set windows. Be like a picture window frame. You want a frame of some sort definitely for the sealing aspect. Typical residential IGU's are 3/4" over all. 2 pcs of 1/8" glass and a half inch airspace.

Millworkman thank u for the terminology and the measurements Looking closely at my window They have a metal edge I will look for that terminology and call Great Lakes glass as well as Clearvue who appears to do there own mfg

@kathleen,

I heard aluminum spacer is the best. How thick is a very "basic" unit?

Nope, aluminum spacer is pretty much the worst option that you can go with....avoid it if you can. I agree with millworkman that you want a 3/4" thick IGU using 1/8" glass / 1/2" airspace / 1/8" glass, however not sure (based on the picture) that you have that much space in the glazing pocket..

When you say metal edge are you talking about the spacer between the lite in the IGU?

It appears that your original IG's were glazed from the outside of your home. Does there appear to be an easy way to get them out of the original frame so that you can get the exact dimensions; including the total depth of the IG?

IMO remove the bow and replac with a nice picture window .

ci_lantro 1/2" thick....that glass would be awfully thin with the space between the panes for the Argon.

Kathleen, I was guessing that your existing IGUs are 1/2" thick overall. So that is why I ran the #'s on 1/2" IGUs. If you are keeping this frame & retrofiting new IGUs, the new ones need to be the same thickness as the existing. Whatever that is. You have to determine that on site.

A friend of ours replaced all of the windows in his house back 3-4 years ago. I recall him saying that just the bay window cost more than all of the other windows put together. To give you an idea of what to expect if you are looking at replacing the bow window.

FWIW, we removed side lites and replaced with full lite IGU's about 10 years ago. DIY, very easy to do and the total cost was around $400. We had a commercial glass company come out & measure; we ordered the units from them & installed them.

We were complete novices for this type of job and only took us a couple of hours to complete. Added time, naturally, for prep and paint.

ci_lantro I am impressed that you installed them. I am NOT that brave!!
