Every fence in Acadiana will meet real wind sooner or later. When it does, the question isn’t only what the fence is made of. It’s how much wind the fence catches and how well the posts hold.
Wind load, in plain terms
A solid fence acts like a sail. Six feet of privacy fence along a 100-foot property line is a wall of surface for the wind to push on, and all of that force ends up at the posts. A fence the wind can pass through takes a fraction of that load.
- Solid privacy (wood or vinyl): catches the most wind.
- Shadowbox or board-on-board with gaps: lets some wind through while keeping most of the privacy.
- Ornamental aluminum and chain link: the wind passes right through.
Posts decide whether it stands
Most fences that go down in a storm don’t break in the middle of a panel. They fail at the ground. A post that’s too shallow, set in loose soil, or already rotting at the ground line lets go, and it pulls the sections on both sides with it.
- Set posts deeper than the bare minimum on solid fences.
- Use heavier posts at ends, corners and gates.
- Tighter post spacing in exposed spots, like open fields and lots that face a long open stretch, spreads the load.
- Galvanized steel posts behind a wood or vinyl fence add a lot of strength.
How the common fences compare
Ornamental aluminum
Wind passes through, it doesn’t rust in humid or salty air, and a damaged panel can usually be replaced on its own. The tradeoff is no privacy.
Chain link
Very little wind load and very forgiving. Falling limbs can bend the top rail or tear fabric, but repairs are simple. Privacy slats add wind load, so keep that in mind on exposed lots.
Wood privacy
Full privacy and the most common fence here, but it takes full wind. Built right, with good posts, deeper holes and solid gate posts, it holds up well. Built cheap, it’s the fence you see lying in yards after a storm.
Vinyl privacy
No rot, but solid panels catch wind like wood does. Ask how the posts are set and whether they’re reinforced with aluminum inserts or concrete at gates and ends.
Before storm season
- Walk the line and push on each post. Anything that moves gets fixed now, not after the storm.
- Trim limbs that hang over the fence.
- Make sure gates latch firmly. A swinging gate tears itself off its hinges.
After a storm
Take photos of the damage before anything is moved, especially if you plan to file an insurance claim. Then get the leaning sections secured.
