It's a mixed bag using Aluminum or Vinyl, I have Aluminum frames and I'm close to the water in Cholla.
My south facing frames after 22 years are starting to show signs of age and some corrosion from the sun, humidity and wind.
As Stuart said the resort sliding doors are hard to open,
The rollers in my South facing sliding doors need to be replaced every 5 years, which is the problem with many of the
sliding doors on the condo's on Sandy Beach. My old neighbor installed many of the doors and windows at the resorts and
did a booming business replacing the rollers on their sliding doors.
My neighbor had Jordan Vinyl doors and windows installed 15ish years ago and all of his sun ocean facing frames are falling apart from
the sun, wind and heat. The others are in better shape.
All of my doors and windows are Aluminum, Jordan brand which were considered good quality windows at the time.
(They went out of business in 2008 from the housing crisis)
I have Jordan brand Aluminum in my Phx house and all are in good shape (they are 17 years old).
This shows how different the environment is between Phx and Penasco's ocean front.
Living near the Ocean in areas like Penasco is hard on most everything because of the Wind, Sand, Sun, Humidity and earthquake tremors.
From May-Oct there is a constant wind flow from the SE which is hard on structures, because of that re-painting is needed
every 3-5 years vs the 7-10 in Phx. It doesn't matter which paint you use,
just being 1000 feet inland helps reduce the damage on my neighbors places.
