Window Missing Something?

I purchased a pre-construction home and I have noticed something odd with one of the windows. There is a gap within the window frame. Is there something missing? Like some sort of window accessory?

Thanks for the response. Does the window trim insert into the grooves?

Looks like a basement window, in which you can add window trim inserts or caulk all around.

It is actually in the bedroom on the second floor. The builder said the perimeter of the window is like this to reduce vibrational transmission of noise as it is close to the railway tracks. But to me it looks incomplete. I think it is missing the window trim inserts as you mentioned. Is that the proper name for it? Where can one purchase these?

Depending on the window construction and installation technique, the window jamb extensions would cover a gap like that. But - it's hard to tell without a full picture of the window including the trim around it.

The jambs are the boards extending perpindicular to the window out to the same plane as the drywall. Essentially the flat surface in your photo you could put a drink on and continues around the window.

Then the casement trim is the 'picture frame' around the window covering the edge of the jambs and overlapping the drywall. There is a small 'reveal' of the jamb edge showing which is a design feature and allows for slight differences in squareness between the casement trim and jambs.

If someone framed in the rough opening a bit too big, the window jambs wouldn't cover enough of the window itself to hide those expansion gaps.

Simple fix - you could use a 3/4" quarter-round against the window to cover those gaps.

To me it just looks unfinished. It needs either trim or caulking in my eyes.

Your additional photos give a lot more context and looks like they could've trimmed it closer to the frame and not left those minor gaps. Here's a picture of the finish of my windows that I got installed in Sept 2020.

Very nice, I notice you have some sort of white trim around the window edges? Is that right?

I believe that's part of the window frame. It's not an add-on.

Silly question, but how do the other windows look like? If they are all the same, maybe take a pic and ask your neighbor?

What you are seeing is called the accessory slot. Its used on the inside for a piece of u trim for jamb extensions, and the outside for brickmold. I happened to have some in my work bag and just took a picture. It goes into the slot and has a u-channel for accepting the interior jamb material. The large piece that extends beside the u is intended to be attached to the window with screws or staples where you cant see it near where the foam around the window is. This slot should not be visible inside or out, but is commonly left visible as brickmold and jamb extension u channel costs money (pennies, but still money) so builders leave it off.

100% they didnt foam behind your jamb extensions, and the windows dont form a very good seal as the foam is only behind the 3-1/4” frame of the window, but NOT behind the jamb extensions.
