I am in the process of designing a home theater room and am looking to see if anyone might have any suggestions for an interior door I am trying to come up with. I was thinking of possibly using a glass or solid core slider since it will substantially reduce the noise getting out of this room and into the rest of the house. However, I also want to be able to have a large opening (9') when I entertain and don't care about the noise. This 9' door would need to slide into a 6' storage area (maybe like a pocket door) or just slide along a 6' section of a parallel wall. A sliding door with three 3' panels where all 3 slide into the "pocket" would probably work best. Does anyone have any suggestions on where I might find something like this?? Thanks.

Hello, I want to install a bifold door in my basement to access the area under the staircase (there is a sump pump behind). It will be a single bifold, about 30" wide x 54" tall. Is there any way I can lock this bifold with a key, to prevent my son and his friends from going back there? I looked but I cannot seem to find anything that will key-lock a bifold door. Thanks in advance lzk
