Trimless Windows: How to Get the Look

Prep the Rough Opening

• Not all windows are perfectly centered in their rough opening. To center them, you may have to shim the sides, top or bottom of the opening. The goal is to achieve an even reveal between the window and the drywall return around the inside perimeter of the opening.
• You can purchase drywall shims or make your own by ripping different thicknesses of plywood.
• Attach the shims to the rough opening using staples or finish nails.
• Always insulate around the window with spray foam or fiberglass insulation.
