Installing Drywall Inside Window Frames
So just curious my basement windows are recessed into concrete. I attached foam board around window and on inside. I then drywalled over that. Any potential issues, do I need to use some other material or framing since it is closer to exterior than a wall. Picture attached.

Hammer,
You should use plastic U channel over the ends of the boards where they meet the window frame.
Or hold off 1/16" to 1/8" off frame and use drywall L-metal/bead mudded in, if you don't want to see the U channel edge.
I looked at bottom or sill, kind of worried now about putting things down on sill and drywall is pretty sensitive. I’m considering now making a box out of wood or only using wood for my sill only drywall rest. Windows are deep and I have 3, I need about 3-4 4x8 sheets of wood. What is cheapest wood I could use that would look reasonable and hold up well?

That seems like problematic detail to me for a number of reasons - not least because it would be so finicky to get looking right. I'm not sure in the long run anyone would want an open 1/8" reveal to attract bugs and dust around all the window frames, and it sure complicates air-sealing.
In the article he says he leaves a 1/8" gap and then caulks it. He also claims it's less labor than trimming with wood.
DC,
谢谢,但我仍然找不到wh的部分ere he says he caulks that joint.
我使用的所有窗户都有一个1 1/4“法兰。大的空间可在框架周围隔离和空气密封。
I got confused, it was actually C L in post #6 below who said that.
DC,
We should start a window company. Ours would have an integral exterior drip-cap with end-dams on the head, and an indent with a gasket on the interior face of the frame to set either drywall or wood casing into.
Funny, I was just looking at a house under construction this morning, and wondering, "why do you have to build the window flashing on site, why don't they make window units that include their flashing?"
Gypsum returns are a very common detail around windows and doors. They are most common in modern homes due to the clean lines, and low end homes because it does not cost much if anything extra for the gyp crew to return around the windows and doors, and it saves on finish carpentry materials & labor. It is only problematic when the framing is really out of plumb.
您的床“拉链条”就像在外部边缘下方的链接上一样，覆盖了窗户上最终的石膏的切割边缘：https://www.homedepot.com/p/ClarkDietrich-1-2-in-x-10-ft-Vinyl-Rip-Bead-L-Trim-1-2-VLZL-10/311364894
这件要被撕裂的件可保护窗户免受干墙泥的侵害，而条带有一个小边缘来运行泥刀。干墙被弄乱并打磨后，通常是在第一层底漆涂料之后，您就可以撕下可移动的部分。然后，您可以在这片修剪和窗户之间填写/密封，以消除空气间隙。
由于这个窗户是如此之深，并且在基础墙（某些斑点中超过2英尺），就像窗框旁边的木材1x12一样，然后将其余的墙壁干燥到内墙看起来很奇怪吗？这将需要更少的木材撕裂，并且更容易完成。另外，我会用正确的木材使用更好的空气密封吗？我仍然会在整个窗台上使用木头。我想到使用PVC代替木材，因为它具有抗浓度，但对空气密封的木材不是更好的木材吗？
The big problem with wood for air sealing is it moves with the seasons, a 1x12 could be as much as a quarter inch bigger in summer than it is in winter. PVC expands and contracts with temperature changes. Drywall doesn't move. All three are essentially completely airtight.
