How To Build A Sliding Barn Door

Use of a sliding barn door allows for more productive activity since the door remains out of the way when opened. Swinging doors present a variety of operating considerations that a sliding door does not. The sliding door opens with objects in front or behind. They can operate easily during inclement weather. However, the doors are built much lighter than traditional doors, to prevent warping the slide track.

Step 1 – Cut the Boards

Measure the barn door opening and then cut the board to the height and width needed to construct the frame. To create a stronger frame, either double stack 2 X 4s or use 4 X 4 wood beams. Since this will produce more weight, decide if the extra strength is a required need.

Step 2 – Assemble the Frame

Use metal braces and galvanized screws or nails to assemble the door frame. Cut a cross brace attaching it to the frame center. For large barn doors, use a diagonal brace on both halves of the frame.

Step 3 – Planking

Place planking cut to the barn door height on top of the frame. Attach these to the barn door frame using galvanized screws or nails. Dab a drop of wood glue at each screw nail head for extra added strength.

Step 4 – Mount the Track

Mount the sliding door track to the top of the frame using wood screws and a power driver. Make sure to use a carpenter level to obtain the exact alignment needed.

Step 5 – Wheels

Use three to four track wheels mounted on the bottom of the door is it will slide along a level surface. Use a bottom track if the door will be higher than the barn foundation, for example, if the barn has an entry ramp.

Step 6 – Wall Tracks

Once the sliding barn door is assembled, measure the track lengths on the frame and install similar sized tracks on the barn walls where the door will retract. Install a wall tract slightly longer to ensure the door will be completely away from the door opening when in a retracted position.

Your new sliding barn door can be painted before it is attached. Some barn doors are decoratively painted. Some have the farm or owner’s name painted across the front. Make sure to use outdoor, weather resistant paint when decorating your sliding barn door. Also, periodic maintenance should include cleaning the door tracking and removing any small particle debris found. Air spraying the sliding track can accomplish keeping it free of debris. Also, inspect track wheels occasionally to keep these in good working condition. They will wear with use and will need replacement, but periodic inspection and cleaning will extend wheel life and door usage.
