Are Vinyl Windows Better Than Aluminum in Florida Humidity?

What Humidity Does To Windows In Florida

In a place like Winter Haven, where long humid stretches are normal, the real question is not just how a window looks on day one, but how it behaves after years of heat, moisture, and afternoon storms.

Humidity works with solar heat, UV exposure, and daily temperature swings, so a window that seems fine in mild weather can start showing problems once summer settles in.

How Vinyl And Aluminum Behave In Humid Weather
