French Doors

One more thought on French doors. I built a listening room/study in an attic space in a prior home, and because of lighting issues, wanted to have a French Door to get more light into the space. I solved for the sound problem by having an EXTERNAL french door and frame installed -- one that was intended to be the front door to the house or the back door onto a patio. It was very heavy, insulated, had double-paned glass, and the surrounding door frame was also insulated and had a rubber weather seal. It looked great, but also was a very good sound insulator -- I had no problem with vibration and the sound dampening was very good.

Considering the dimensions of the room, but not knowing the location of the opening, I have to wonder if you really want to put a door there?

I've used double glazed glass windows and they do use thin glass. For a little more money, they will put thicker glass in the window. I would strongly recommend that.

Unsound,
Good point. The room has that single opening on the back of the 13' wall. This is actually the "formal living room" that I will convert into a music room. As you enter the house, it is the first room on your left.
That was one of the reasons for getting a french door. But I am open to various options and ideas.

Rdavwhitaker-my thoughts exactly. He can actually order a custome size that will work fine. Double doors with side glass? It's gonna be pricey. My guess is 1-2k plus install. They don't need to be wood either. Vinyl comes in many colors.
