Just looked at your pics again and realized that while the motorized retractable rolling screens I posted earlier might work for three of your four arches, you need something else at the stairway arch so that you have a way for people to come and go. So, here is another website that might be helpful. Don't know if these come in a version tall enough or wide enough to cover your arch but maybe... Here is a link that might be useful: Insect Screens For Bi-fold And French Doors

If you do laundry (washing & drying) with the doors open then I don't see a need for them to be louvered at all. If you do run the dryer with the doors closed, then yes, they must be louvered. Dryers pull a lot of air and must "breath" freely. Check with your user manual for "closet installation" for the washer & dryer. I just checked with an Electrolux manual and it states: "Closet door ventilation required: A minimum of 120 square inches (774.2 cm�) of opening, equally divided at the top and bottom of the door, is required. Openings should be located 3 inches (7.6 cm) from bottom and top of door. Openings are required to be unobstructed when a door is installed. A louvered door with equivalent air openings for the full length of the door is acceptable."

Paintguy, thanks! I'm so sorry that you have all those louvered doors. LOL, I sincerely appreciate your sympathy! Actually, I went ahead and started brush painting the first set and it's going pretty good. I think I found a system and it's not so bad. Using good paint (BM) and a good Purdy brush and keeping it a bit on the dry side to avoid runs. I have them standing up in the garage and can easily turn them to check for drips, etc. I think I'll forget about the sprayer on this project. I think louvered doors look really nice if very neatly painted and look extremely crappy when when not and I'm not willing to risk my husband practicing on these ;-) I'll tell him to check out the Graco sprayers if he wants one for other projects. Maybe the next go around (which I hope will be many years!) he'll have plenty of practice and I'll let him spray paint them then. I see that Magnum is made by Graco, are they just as good or should he stick with Graco?

Patricia Colwell Consulting ... Hope this helps clarify our project. Current door to bathroom is where "proposed linen closet" is. We're in "over 55" community in 2/2/2 home with limited storage. I have walk-in closets in both bedrooms & a 30x30" entry closet PERIOD. MAIN QUESTION: Could closet door be flat bi-fold, louver (main advantage to both being SUPPORT for closet organization), or pocket. I APPRECIATE ANY THOUGHTS YOU MIGHT HAVE ... THANKS!!
