An experienced company can confirm the right fit for your house with a quick inspection.

Why Humidity Is the Main Decider

In a humid climate, warm moist air condenses on cooler surfaces, and windows have more temperature change and seams than most parts of the envelope. Wood is hygroscopic, so it swells, and vinyl is hydrophobic, so it does not absorb water, though it expands from heat.

Around the Gulf Coast, the job is to keep wood dry enough to avoid rot and to pick vinyl that handles thermal movement.
