Chicago Remodel: Slider and hinged doors
I'm about to embark on a first floor remodel in Chicago. I'm remodeling the family room and am considering replacing the eight foot sliding door. It's 40+ years old and functions, but as it's an old aluminum door, I can't imagine it's very energy efficient. It faces SW.
I also need a new hinged door that connects the kitchen to the sun porch -- so while I want a good door, it doesn't have to be the best quality because the sun porch is entirely enclosed
I love the idea of aluminum for both doors, but understand that at least the slider needs to be thermally separated. I've looked at Fleetwood, but can't justify the cost. I can spend up to about $2500 for the slider plus installation. I just can't justify $5000+.
Are there aluminum options that are good quality, affordable, and appropriate for weather extremes? If not, what would you recommend that may be available in the Chicago area? I'd like doors with as much glass as possible, something that will go well in a late 60's contemporary home and should last 20+ years.
Thanks so much in advance for all input.
