I looked into the nana wall and several other options as well --- They are really cool, but in the end, we determined that our house location and set up didn't warrant the expense of these. Now, if we had an awesome view, we might have done this. My recollection of this in terms of pricing for Nana Wall and some of the other brands: I believe it was about $800 a foot for this --- so for a 12' opening, it worked out to about $9600 --- I looked at several manufacturers and the pricing was all in that ballpark. Will your doors open to a patio, a screened porch? This was a concern for us in this decision. We ended up putting a screened porch, so the Nana concept would have been great, because opening the doors wide would still be within the screen.... thus no bugs, etc invading the house. If not, you might want to consider with lights on in the house and the doors wide open, you might get every moth in town visiting! Another consideration is how to stack the panels. In our plan it was working out to be awkward --- and the "stack" would have been in the way. Just make sure that if you go with these, you have that planned carefully... some of them can stack inside a wall, which is pretty neat. Another consideration to think about..... look back at your pictures linked.... the transition from inside to outside.... if you are trying to make a very open space, be careful of that little half step transition.... it looks like a tripping hazard to me. I would want either a full step down, or preferably a level transition there to open up the space. The top picture has a small step, which can be an ankle breaker! Finally, if you are trying to maximize your view through the house straight out the back, maybe consider an odd number of doors so the exact center is glass, not the door frames meeting in the middle (your bottom picture does this glass in the middle way). If you think about your set of 4 doors concept, the dead center part will be about 8" of door frame, vs. glass. If you use 3 or 5 panels, the center view would be glass. This is why in the first few pictures they show the doors open, because it looks way better open than closed. But in the last picture, the view is great regardless. And.... while I think the standard is to have the center 2 panels open on french doors, it makes furniture placement more difficult, so just make sure you've thought about it! Good luck would love to see pics of the view, etc! Rachel

I know I know. that what my thinking as well. but then what is the best way to block the oppressive western sun from cooking us through the sliding door? regular blinds just arent a good option (we have 2 boys under 3 yrs old who like to pull on things, and how would blinds over a slider work anyway? how do you get though the door when they're down?). growing up we had curtains covering our sliding patio door and I hated it. this may be one of those times when convenience trumps quality. but how bad can big box jeld wen be? are we talking delamination of the clad exterior? water leaks? poor thermal performance? fogging of the glass? or do the just generally fall apart?

We replaced our French patio door with a slider last year (here 27 years) and we are sorry we didn't do it much sooner. It is much easier to operate since the french door was so heavy and it was a pain to open and close as compared to the slider which operates beautifully. We didn't replace it with a French styled slider, ours has minimal casing to open-up the view. It gives our room a lift.

a few years ago I had Wonderful Windows come out and give me a quote. They said they would have to custom make my door. My slider is 9 ft X 8 ft. My house was built in 1978. The slider in our living area is in bad shape. There is another slider in the master bathroom (of all places) right next to the toilet. That one is smaller.
