Vinyl Window Replacement Vs. Wood Windows in South Louisiana Humidity

The Effects of South Louisiana Humidity on Windows

The Gulf air in South Louisiana stays damp most of the year, and your windows feel it every day. Choosing between vinyl and wood windows in this climate means focusing on moisture control, durability, and energy performance rather than just looks.

Material Comparison: Wood vs Vinyl

Humidity, salt, and sudden temperature swings are the core problems. Because wood is organic, it can wick moisture, swell, and later crack while also attracting insects if not sealed and maintained.
