Vinyl or Aluminium Sliding Doors in Florida
Both are common here and both work. They fail in different ways, which is really what should decide it.
Aluminium
Strong and thin. Because the frame carries the load easily, you get more glass and less frame, which is why it suits big openings and modern builds.
The catch is that aluminium conducts heat. On a west-facing door in August you can feel the frame warm to the touch, and that costs you on cooling. Better frames use a thermal break to reduce it.
Near the coast, salt is the other consideration. Aluminium handles it reasonably well, but the fixings and rollers are what corrode first.
Vinyl
Much better at not conducting heat, so it usually wins on energy efficiency. It also does not corrode, which makes it a sensible pick closer to the water.
The trade-off is strength. Vinyl frames have to be thicker to carry the same glass, so you see more frame. On very wide openings that becomes noticeable.
Vinyl also expands and contracts more with heat. Quality matters here, and cheap vinyl in full Florida sun is where you see warping over time.
What actually determines lifespan
In practice, neither material is usually what fails. The rollers, track and seal wear out long before the frame does, on either type.
A well-maintained aluminium door outlasts a neglected vinyl one, and the reverse is equally true. Track cleaning matters more than the material choice.
A rough guide
- Very wide opening, want maximum glass: aluminium
- Energy bills are the priority: vinyl, or aluminium with a thermal break
- Close to salt water: vinyl, or budget for roller replacement sooner
- Modern look: aluminium, for the thinner sightlines
