How to Build a Bi-Fold Window Shutter

A bi-fold window shutter provides a lovely window treatment, lighting control and a fun project. Window shutters vary depending on the size of the window, the size of the louvers, the ability to open and close the louvers, and how many panes make up the shutter.

Build Bi-Fold Shutters

Measure the window from top to bottom and side to side. These measurements determine the size of wood you will need to buy. Subtract 4 inches from the width measurements to determine the length of the louvers. Twelve louvers per window pane is standard. For a bi-fold, you will need two panes, so 24 louvers. The width of the louvers creates a specific look, so pick out large louvers for more lighting control or small louvers for a detailed style. The peg sticks should be the length of the louvers plus 1 inch. Buy the wood pre-cut to save time or if you don’t have a saw or experience with woodworking.

Lay the louvers on your work station with the peg sticks. Glue the sticks on the back/unfinished side of the louvers, so that a half inch hangs over both ends. Allow 24 hours to dry.

While the louvers are drying, lay the wood frame pieces on your work surface in the shape of the shutter. You will have two panes that make up the bi-fold. Measure 12 even spaces down the sides of both frames and mark with a pencil. Drill a hole big enough for the peg sticks, but no bigger.

When the louvers have dried, glue the peg sticks in the holes on the sides of the wood frame.

Glue the frame pieces together. The edges should have a diagonal cut, so they fit together like puzzle pieces. Allow 24 hours for the peg sticks and frame pieces to dry.

Drill the magnetic catches to the frames. You will need one catch for the top and another for the bottom of both frames. Tighten the screws and swing the shutters to make sure the bi-fold works properly.
