The front wall, with the two glass doors and picture window, will have drapes with 1 layer of lumitex.
In the rear of the room, behind the listening position, both the left and right walls open to the house. Prior pictures in this thread show the back of the room, with the wide stairway flowing down into the room on one side, and the opening opposite that leads to the lower floor bedrooms (3), and which now includes my wine cellar.
There will be curtains which will draw across both openings in the rear of the room, and these drapes will be lined with 3 layers of the Lumitex. This will represent about 25% of each wall.
The back wall has the custom panels mounted behind the fabric-wall.
