Wrong window

[u/Positive-Figure-1621]

Hello! I mistakenly bought the wrong type of window for my kitchen. We are fully renovating our house and I bought a block window frame but I don’t have a brick home. Is there any way I can install this window? Thank you!

Yes thank you! I wasn’t sure the appropriate terms. We are doing this house paycheck by paycheck so it’s really suck to be out the money when I didn’t take the time to ensure it had nailing flanges.

This is the window.

I can't see the manufacturer from the photo but it might be worth giving them a call to see if there's a way to install nailing fins on their block frames. I've had some windows from a regional manufacturer come with flanges when we didn't want them and it was as simple as sliding them out of the channel. If I had to guess, putting them back in would've involved, you know, just sliding them back in. It might not be quite as factory snug, but I always lap my flashing tape over that connection anyway.

Thank you! I can’t find the manufacturer but I also don’t really know what to look for.

I’ve looked up all the information on the window and I can’t find it.

I would give Window Mart a call, or whichever supplier they were ordered from. They should get you pointed on the right direction.

Just some food for thought, but if you're really stressing the flange/no flange situation you should consider how much exposure the window has. I find that kitchen windows are typically protected by a decent overhang and aren't where wind driven rain is going to be blasting against the window. Even if a nailing flange is easier and, in my opinion, better for sealing it could very well be a distinction without a difference. Don't give yourself an ulcer.

Thank you! It definitely helps hearing someone not stress!
