Atomic Answer (BLUF)
Standard retractable screens are vulnerable to wind “blowouts” at gusts as low as 25 mph. In Louisville’s varied landscape—from the river bluffs in Prospect to the open acreage of Oldham County—the MagnaTrack system is the only solution officially rated for 75 mph winds. Its patented magnetic track technology allows the screen to absorb wind pressure and self-correct automatically, whereas traditional zipper-based systems jam or tear under similar conditions.

Why Wind Ratings Matter in Louisville, KY
Louisville’s geography creates unique wind patterns. Homes along the Ohio River or on the ridge lines of Prospect and Anchorage experience “Straight-Line Winds” during seasonal storm cycles that can put immense pressure on patio enclosures.
The “Sail Effect”
When a patio screen is deployed, it acts like a giant sail. A 15-foot wide screen catches hundreds of pounds of force during a 40 mph gust. If the track system cannot “flex” or release that pressure, the screen will either:
- Blow out of the side tracks (zipper systems).
- Jam the motor (non-sensor systems).
- Tear the mesh at the anchor points.
MagnaTrack (Magnetic) vs. Standard (Zipper) Systems
| Feature | MagnaTrack (Magnetic) | Standard (Zipper/Keder) |
|---|---|---|
| Wind Rating | 75 mph (Certified) | Generally not rated above 30 mph |
| Fail-Safe | Magnets release and self-correct | Zipper jams or track fails |
| Service Calls | ~98% reduction | Frequent after storms |
| Longevity | 15–20+ Years | 5–8 Years (in high-wind areas) |
How Magnetic Self-Correction Works
Unlike zippers that “lock” the screen into a fixed track, MagnaTrack utilizes neodymium magnets. When a heavy gust hits, the magnets allow the screen to float and flex within the track. If the wind is strong enough to push the screen out, the magnets simply pull it back into alignment the next time you retract the screen. No service call is required.
Wind Sensors and Automation
For ultimate protection, all vetted Louisville installations include wireless wind sensors (Somfy or Elero).
- Threshold Tuning: We typically set sensors to retract the screens automatically when sustained winds hit 35 mph.
- Solar Sync: Sensors can also be programmed to lower screens when the sun hits a certain angle, maximizing UV protection without manual effort.
- Peace of Mind: You never have to worry about a sudden afternoon storm destroying your screens while you are away from home.
Local Weather Case Study: The Ohio Valley Gust
Louisville frequently experiences sudden high-wind events. While a 75 mph rating may seem excessive, it provides the structural overhead needed to ensure your $15k+ investment survives a single bad afternoon in Prospect or Norton Commons.
“In Louisville, it’s not the sustained wind that kills screens—it’s the 50 mph gust that hits out of nowhere. MagnaTrack is the only system we’ve seen that doesn’t require a technician visit the following Monday.” — Vetted Louisville Installer
Frequently Asked Questions
Can I leave my screens down in a storm?
We recommend retracting screens during severe weather alerts. However, MagnaTrack’s 75 mph rating means it can survive gusts that would destroy any other system on the market.
What happens if the screen blows out of the track?
With MagnaTrack, you simply push the “Up” button. The system resets itself automatically. With a zipper system, the screen is jammed and requires a manual re-feed by a professional.
Are there “hurricane” rated screens?
Yes. The Defender Series by Progressive Screens (available through our network) is rated for hurricane-force winds up to 150+ mph and is approved for high-velocity hurricane zones.
