I'm not sure you're going to be able to do this. If you're building the wall yourself, the 2" is unnoticeable. I am here to tell 'ya, since I have 15 pocket doors made in all 2x6 walls. I have a metal and glass door between my mudroom and kitchen so my dogs can see in and I can see them at night. I used one of those great screen doors where it's glass on the bottom, screen on top and the glass on top moves up and down. It's fantastic. I think the thing is, one doesn't need a metal and glass on the interior, so a thin, interior door is fairly difficult to find. OTOH, you can find great exterior doors of a gudzillion styles in exterior doors. If it's the only 2x6 wall in your home, I promise you're not going to notice. Plus, the way my dogs jump? I don't think I'd want 1) a full view glass window, or 2) a skinny door. Christine

One brand you did not mention is Loewen. In my recent search for a sliding glass door (wood not vinyl), two brands stood out from the pack: Loewen and Marvin. Unfortunately, the Marvin and Loewen were also the most expensive that I saw. But I guess you get what you pay for. Between Marvin and Loewen, I thought Loewen was slightly superior. Loewen comes with Doug Fir standard. Marvin has Doug Fir as an optional upgrade, which would raise the Marvin price substantially. Loewen also just looked beautiful and felt beautiful. Marvin looks great too. In the end I chose Marvin for a couple of reasons: I was going to have the wood painted, so it wouldn't matter to me that Loewen had the Doug Fir. Marvin was less expensive than Loewen. I believe that the price depends on your region. I could only find a couple of places selling Loewen in a 25-mile radius, while Marvin was sold at a dozen places in a 10-mile radius, so the Marvin sellers were competing with each other and the prices were better. I believe some people have reported that in their area, Loewen costs less than Marvin, so it really depends on location. Also, customer service was a factor in my decision since Loewen was not well-represented in my area. Perhaps they are in your area, and I recommend you check out both Marvin and Loewen. BTW, I am replacing a Pella sliding glass door, and having lived with it, would never get a Pella sliding glass door again.

gidgetgirly, thanks so much. I planned it myself but I am a kitchen designer and took a very long time to plan it. came up with a million iterations for the space which had a lot of difficult problems to overcome. I found my invoice, I paid $258 for the pair of grilles. The cabinet company ordered them for me so that they would be the correct size and so the doors accepting them could be modified with a wooden band and screws to keep them in place. thanks again

Companies like Tru-Stile will replace the panels in their panel doors with glass. They are fairly expensive doors, because they are essentially semi-custom, made-to-order but not as expensive as full custom. http://www.trustile.com/
