Windows let in light and air into a room, and sliding glass windows or doors are the most functional of these, as they never occupy any space within the room. These doors are opened and closed every day and become that much more functional if you have the right sliding door covering ideas as part of the window treatment for them.

You can use vertical cellular shades as they have very good insulating properties. On days when it is hot and the sunlight is bright, these shades can filter the light. They also trap the air between the windows and the shades and this can help in reducing the load on air conditioning.

You can also cover the sliding glass panels with sliding track blinds and its large panels of fabric on a single track can give you more privacy. Using drapery over these two coverings you can add elegance to your window treatment.
