Vinyl Window Replacement Vs. Wood Windows in South Louisiana Humidity

How Humidity Affects Window Performance

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.

Let’s break down how each material behaves in the South Louisiana climate and what to ask for when you order new units for homes in Mandeville LA and nearby.

Vinyl vs Wood: A Material Breakdown

Three forces drive most window issues here - humidity, salt in the air, and fast weather swings. Wood absorbs moisture, swells, and dries out, which can open up joints and invite rot and termites. Vinyl, being non-porous, does not rot, and modern formulations resist UV degradation, though prolonged heat buildup can still cause some expansion.
