Anyone with trim carpentry experience can build their own studio window if they plan correctly, take their time, and follow these steps. You will need at least one helper when installing the glass. This example project assumes the window is set in 2'' x 6'' wall with multiple layers of drywall, Sheetblok, etc. on both sides. Procedure is the same for single wall of any thickness. When installing window in two separate walls, there will be separate inner blocks for each pane.
Tools needed; hand saw or circular saw, sanding block or orbital sander, drill, screwdriver, level, utility knife, plane, etc. A note about parallel vs. angled glass; Although angled glass is common in professional studios, we generally suggest parallel panes for most applications.
This is because the air gap between glass is more important to isolation than an angle is. Unless the panes are several inches apart, the angle would probably not be large enough to make any difference, and would lessen the air space. If you prefer to angle one or both of the panes, there are additional tips at the end of the directions.
These instructions assume you are installing two panes of glass, in parallel, with the largest feasible air gap in between. Use very high grade pine with no knots, or finish grade poplar, for best results. Do not substitute plastic or Plexiglas for real glass.
