Cathy Schwabe Architecture Hi - your question is one better addressed by Fleetwood -- the LF cost is certainly a place to start - -but you'll want to also give them the height -- and if the door is to slide within the frame -- think of a traditional sliding door with one operable and one fixed lite -- if you need screens ( as this requires a separate track position -- as in a wider track - and or slide like this one where track is 2x the door width - and do the panels need to all go in one direction and port over each other or can they open in the middle like this door - half to each side -- this too affects track width and length. Your choice of finish for the frame and also for the glass will affect costs too.
In the greater Bay Area, the rep is Collier Warehouse --
90 Dorman Ave San Francisco, CA 94124
(415) 920-9720 . The person I have worked with the most closely over the years is Dave Freer -- but I expect that you could pose your question to anyone and get the information you need, Alternatively -- see if there is a rep closer to you -- which you should be able to find through the Fleetwood web site.
Hope this helps --

Cathy Schwabe Architecture Hi -
Thanks for the question -- no this house is in a pretty temperate climate - gets down to low 30's on occasion in the winter -- but no snow - and into the high 90's on the rare day in the summer -- but usually winter days are in the 50's and summer days in the 70/to the high 80 range -- low humidity too.
Fleetwood has other options for these doors with a thermal break - which would improve thermal performance and I believe some options on glazing. These are double glazed with a low e coating -- we worry about heat gain more than heat loss - but we did not use thermally broken option.
I would talk to them directly -- and might be a good idea to ask for architect references in your area so that you can ask them about performance and comfort --
The near zero threshold used here ( 1" difference between inside and outside) is not something I would do in snow country - unless you had a much better cover over the doors than is used here. If you get tons of rain but not so much snow -- while this threshold assembly drains well if you wanted this low threshold situation I would use a linear trench drain along the threshold between it and the stone paving to really make sure you could capture enough water and take it away.

Best,
Cathy

cblemkau Hi Patrick,

Thank you so much for contacting me. That was very kind of you. As it turns out we went in another direction. But I will say, your doors look fantastic.
