How do I adjust a rough wall opening to fit glass block installation.?

Question

I am trying to brighten up a bathroom by installing glass block window through an interior wall between the bathroom and bedroom. The joists are on 16 in centres but that does not allow for a nice fit. I probably need to cut off one of the joists in the opening and add another, just not sure how to add a side to the opening

Answer 1

--Joists are in the floor, studs are in the wall.
If the wall is non-load bearing, simply cut away the unwanted stud 2" below and above the opening (use a reciprocating saw right through sheetrock you will patch); Add 2 horizontal 2x4's top and bottom to frame out the opening (screwing will cause less frustration and damage than nailing), then finish with 1/2" sheetrock. If your block will work out in a 30 1/2" wide opening, just cut the sheetrock 1/2" short of of the 2 outside studs, and cover those studs with new rock. To stop the width not at a stud, add a vertical piece of 2x4 - simply slip it in and screw through the rock. remember to calculate you opening width to accommodate 1/2" sheetrock. If you can't work sheetrock consider a cased opening, ie 3/4" wood and trim.

Answer 2

Mark the outline of the window on the wall and put the center of the window in the middle of a joist(2x4).
Remove the plaster to the center of the joist at left and at right.
Now cut the center 2x4 3.5 inches below the edge of the window and 3.5 inches above the top.
Make a sandwich of two 2x4 and a 1/2 inch of plywood the lenght between the joist on the right and the joist on the left (should be 30.5 inches),put one on the top and one on the bottom.
Nail a 2x4 to the left and right joists under the sandwich on the bottom to the floor and above the one on top to the ceiling.
Decide how wide the window is goin to be and put a 2x4 on each side.
The frame is finished.
Before you start measure carefully the glass blocks and allow for the thickness of the plaster between the blocks.

Lowes house development has a video tape which you could buy on putting in glass block partitions. On the way to offer you an inspiration of the level of trouble for this cool dwelling improvement assignment. That you would be able to even add lights into your glass blocks! Framing with wood on the backside and glass block on prime would definetly be less expensive and commonly a bit safer.
