Zone 4 or 5 is not mild but I am sure it depends where you are coming from. Given your username, mild is not a word you should be using.

Zone 1 and 2 are mild.

There are marine variants of other zones that are milder.

I would not use all aluminum windows outside of zone 1 or 2.

Thanks. Thermally broken it is then.

Are you looking at storefronts? I would think that would be a really cool look for your program.

just_janniI looked at commercial glaze. It looked good. All aluminum windows were almost as good. I thought factory glazed product would be better in terms of insulation and for doors.

Curtain-wall may be ok residential, but definitely not on storefronts. No where near tight enough. Curtain-wall however will be quite considerable more than storefront and maybe a bit more than aluminum windows.

What is a curtain wall? I have a few wide openings but they will have panels. I am trying to cut down the cost. As it stands, the glaze will take up about 25% of total. Any suggestions how to reduce the cost without losing the open feel of the glass?

I have no idea what type of expanse you are trying to cover with glass. I have seen your posts but do not recall the elevations and or the layout. This is a typical section and this is a link to multiple elevations of curtain-wall.These are all commercial but the look would be similar. I would venture a guess but you would be looking at $200 +/- a little bit per square foot for residential curtain-wall.

These are Fleetwood, thermally broken.

The panels are big enough at 5.5' x 9' they are glazed onsite into the frames using 4 workers due to weight.

Western makes a similar window.

I have a few wide openings. 192" wide 120" tall opening for pocket or folding doors. 132" wide 120" tall for double swing doors. 216" wide 96" tall opening for 3 fixed panels. Others are smaller, 96" wide 780" tall picture window, and a few 36" wide 108" tall picture windows.

I can't still tel how curtain wall works. Anyway, it probably increases cost more than I would like.

Jeffrey R. Grenz, General ContractorThey will great. That's about the size of my bigger glaze. I was a bit disappointed with Western multi slides. The stile was thicker than I expected. Which would be better, 4 door pockets or folding doors?

millworkman Here are my plans. I would appreciate if you have a chance to take a look.

The big set is a center open 22x9 that also has screens as the client did not see themselves leaving the house wide open without screens.

Because of wind exposure these are rated at 110+ mph and also have a substantial frame thickness, but Frleetwood's section is deep vs wide.

I'd certainly want to talk to somebody local who's had them installed in your temperature zone.

Look at the energy numbers very carefully as even thermally broken through aluminum frames are gonna be cold

Jeffrey R. Grenz, General ContractorThe opening looks bigger than 22x9 to me. Or does 22x9 apply to one panel? Does the screen comes with the window/doors?

For this level of window screens are additional cost, not included. Screens are not practical for stacking sliders.

I've only used stacking or folding doors when I have a lot of covered patio to shelter.

It's probably time you get in to these window dealers look very carefully at wind and water management systems for the big doors & not take that for granted that all. Make sure you understand who will be responsible for making sure you purchase windows that perform properly in your environment.

Jeffrey R. Grenz, General ContractorThanks! The opening is not protected at all from weather. It has an overhang about 5' deep. Otherwise, it is open to outside directly. I will ask the window dealer or see what others do.

snowcounty, I cannot tell much from your pictures as they get blurry. If you want to email them to me as a pdf I can take a better look for you. millwork4u@gmail.com
