Sorry, ronnatalie ~ I suppose I was thinking of American vs international plugs, which have (in assorted configurations) fat or slim round prongs or flat prongs or prongs of differing widths and in different combinations of round and/or flat, with 2 or 3 or 4 prongs per plug, set parallel or angled, centrally or off-center... and on and on. As long as the plug's prongs properly fit the outlet they were designed to fit in order to transmit the electricity for which they were designed, there really isn't any practical reason for using any one combination of prongs rather than another. No matter all the different appearances: each conducts the electricity to the appliance. The only consistency is that various countries have a preferred design. The preferred design is the local convention, and the convention is not due to practicality or a requirement of electrical transmission, but simply because sometime somewhere someone decided that only a particular design was to be used. Consistency does not have to have a practical or logical reason for existence; it simply has to be accepted by enough people for it to seem reasonable to be accepted. So whether it's about two-pronged plugs or in-swinging exterior doors, local convention rules local usage.

Nancy and Others: I have also been researching what to replace my great room sliding glass doors with (one 6 ft wide and two 9 ft wide). Here it is, already December and I haven't made a decision! We bought the house in 06 and these are the orig that came with the house. I spent last winter stuffing kitchen towels in between the sliders with a spatula. Not the most attractive thing for the room company walks into. Originally, I thought of going with french doors but the prices quoted were so outrageous and since we don't plan on staying here more than 3 or 4 more years (as it is, we'd take a bath if we sold now with home prices as low as they are now and we wouldn't be able to get what we paid for it), I don't know if it would be wise to invest that much money. I'd been thinking of going the sliding door route once more. Someone above said french doors are tighter than sliders and thoughts of all those kitchen towels between the sliders last winter have me shifting back to french doors. I also want the blinds for the same reason you do....five dogs (3 pugs and 2 shi tzus). One thing I've learned talking to people at Home Depot and Lowes....the town I live in won't sign off on french doors that swing out. In the south, like Florida, they are preferred because of hurricanes pushing open doors that swing in, however, they are not permitted here. I assume it has something to do with snow and ice on the outside preventing exit in case of an emergency. I guess your posting was a couple of years ago so it may be too late to say to check with your building dept first. I'm curious to hear what you installed and how happy you are with it. Daisy

I find that the patio and French doors are more weather tight and the weatherstrip is very easy to replace and can be found in more places. Andersen, Peachtree and Reliabilt are all pretty good products.

I agree with Fori, you are talking to the wrong sales people. For years early in my career, seems almost all I did was change out sliders to french doors. For your opening size and situation, you could use several combinations of door and sidelight combos. For example, a pair of 32" swinging french, with a 32" fixed sidelight. If your rough opening won't accept that, perhaps a 30" sidelight and/or 30" doors.
