Wow, 800 to install one window on an open wall? That sounds crazy. I don’t know anything about mulling, but installing that window isn’t very difficult.

Typical mullion is a 2x4, If you install a 2x4 can you get the windows to fit?

Actually it's two 2x4's to give load support.
If the original window had no mullion, then it won't need the support of two 2x4's
as it didn't have them before.

Yeah, I thought so too. I'm not opposed to learning how to install one so I may just order the window and do it myself I there's no other way.

You mean using a 2x4 between the two windows right? Looking at the back of the existing windows from the inside it looks like they're just fused together. I'm not seeing where a 2x4 would go so I don't think there is one currently. Apologies if I misunderstood your comment.

Would I just need to wrap the 2x4 with aluminum flashing afterwards if I go that route? In my head I can visualize how to do it, it's just the lack of materials / making it look clean & intentional is the problem. Thanks for the help.

With vinyl windows the mullen is a snap on piece, normally. OP why do you have to take apart the current windows if wanting to reuse?

Not wanting to reuse. I would remove the existing windows completely and replace with these aluminum windows if possible: https://www.lowes.com/pd/ReliaBilt-...n-x-60-in-Actual-35-5-in-x-59-5-in/5013113765

2 of these side by side, mulled together somehow if possible. The Lowe's installer wanted to use a single unit vinyl replacement window but at nearly $2k for the window + labor, so I'm looking for alternative solutions.

Yes, all your doing is creating an opening to install a typical one window on each side.
The wood Mull would be inbetween the two windows.
However the windows will get installed seperatly on each side.
And yes you could cover with flashing or wood trim.

Way over priced on that size of window IMO. Those two with a fin would need a 2 - 2xs between them . then a filler piece with a custom aluminum cap . correctly done and sealed with a good caulk will last a long time.

That clears it up - Thank you both!

I was thinking because the windows are protected with the porch roof from rain, just remove the fins over the mull and seal it well calking wise.

Not a good ideal IMO center will be to weak. 5' tall not much support.

mmmm ok, as they are alum and not vinyl, my thinking was they are stiff enough, but two is better,

Put a 1x4 or 2x4 between them and cap it with aluminum coil stock. Or see if another mfg's mull kit would work, such as Pella's aluminum mull cap.

What climate zone are you in? The u factor of those windows is pretty bad.

 

[XSleeper]

I kind of thought the okie part of okiedude gave his location away. Or not.

 

[pumpkinscastle]

Ok, got it. Still, for Oklahoma you really want more efficient windows. If you go through the trouble of window replacement, upgrade to a better window. I think you will regret a u factor of 0.52. If you are unconcerned about energy savings, then surely comfort should be an important consideration. Good luck with the project.
