I need advice on how to best trim my basement window.

What I have:
50X48 egress basement window.
2x4 stud wall and sheet rock in front of it.

How do I trim it out. At home depot the guy told me to get luan board to trim it out. It makes sense to me because
a. its moisture resistant
b. Dry walling around it would make it impossible to remove the window to get out.

So here is what I invision. Box the window with luan board. Then do I trim around it? Or do people mostly mud and tape it to the drywall?

How deep is it from window to sheetrock?

If framed correctly, u can use 1 by to extend to s/r. If distance is to great use 3/4 inch one side good plywood.

Trim with 2 1/4 inch casing.

Good luck

Please know I'm just a hacker at this. Don't know exactly what your saying creahands.

Here is what I invision. So I have my rough in framing flush with window frame (inside of the window frame that is). The distance from the s/r to the window itself is 8". I have less than 1/4" to work with for thickness of the 8" casing material.

So as a hack, I've decided just to lay a 8" luan board on all four sides flush to the drywall. Then instead of leaving any reveal for trim. I'll just flush mount the trim since luan board looks horrible from the sides + it's a very small thickness to work with to even try to reveal.

Maybe I framed it wrong from the beginning. I think it is correct, the window is just hard to work with because of its nature. I'll post pics of what I did, so that next time I do this (I plan on moving in 3years and building out another man cave), I'll get it right with everyone's help. :)

Seeing as it is already framed,use 1 inch wood corner guard as the trim. This will cover raw edge of paneling and s/r.

Sounds good, thanks Chuck.

No problem. Glad we could help. Good luck with your man cave.

Not having any reveal around a window is not the biggest boo boo ever made. However, if you really want to hide this little boo boo, here is what I would do.

Rip luan to 9 ", (or something greater that the distance between the window and the surface of the drywall), cut to length.

Rip some 1/2" plywood into 3/4" strips.

Cut plywood strips about 2" longer than luan strips.

Glue the plywood strips (1/2" edge) to the back side of the luan, flush with the leading edge of luan. Let luan stand proud of plywood slightly.

To glue, coat the plywood and the luan with wood glue, tack with a couple of small brad nails. Sandwich the luan between the plywood strip and a scrap piece of 2x4 and clamp. When dry sand edge of luan flush with plywood.

Trim end of plywood strips on the luan that will be used for top and bottom, flush with luan.

Trim end plywood strips of side pieces the 3/4" longer than luan.

Rip luan to finish width. Since this is not likely to be the same on all sides, measure and fit each side individually. For tight fit against window rip 1/16 greater.

Cut back the drywall around opening 3/4 to 1".

Run a couple of beads of Liquid Nails on the back of the luan and install. Use 2 or 3 finish nails through plywood strips to studs and 2 or 3 through the luan. The luan is so soft that the nails are likely to pull through, therefore the Liquid Nails.

Install your casing. Caulk your reveal and all joints of the luan. Between the glue, the caulking and the paint you should not be able to see either the joint or the edge of the luan. Do not use silicone, it's not paintable

No one ever has to know.
