Window Toppers

• Window toppers are an ideal window treatment for this style of door because they do not hide the architectural design of the door. Install curtain rods and window toppers above the door where only the bottom 2 to 3 inches of fabric overlaps the doorframe. Window toppers are convenient because they allow the maximum amount of sunlight to enter the room and do not hinder traffic flow in or out of the doorway.
  
  

Sheer Curtains

• If you want a window treatment that completely covers the door without screening out large amounts of natural sunlight, opt for sheer curtains. Sheer curtains come in a variety of fabrics, colors and textures that add interest to a metal French door design. Choose sheer curtains in white, off-white, beige, tan or eggshell for a light, airy vibe. Sheer curtains are a suitable option if you want to leave your curtains closed most of the day, though they do not provide a large amount of privacy.
  
  

Tab-Top Window Treatments

• Tab-top curtains are a functional window treatment for metal French doors. These curtains are constructed with thin, looped fabric strips, attached to the top of a curtain, that allow the curtain to slide easily across a curtain rod. This curtain design allows you to pull the curtain back and forth allowing more or less sunlight to enter the room. Tab-top curtains are convenient for a metal French door design because you can slide them open and closed as you go in and out the doorway.
  
  

Hourglass Panels

• One of the most well-suited curtains for a metal French door is the hourglass panel. Hourglass panels are hung from small rods inserted at the top and bottom of each French door. The panels fit snugly and are pulled together in the middle with a strip of fabric, decorative rope or ribbon. The result is a window treatment that has an hour-glass shape.
