Small-Insect Screen | Coastal Florida

No-See-Um Screen 20×20 Mesh

20×20 no-see-um screen uses a tighter fiberglass weave to help keep out tiny insects that can pass through standard pool screen. It is especially useful near coastal, marshy or humid areas where gnats, sand flies and no-see-ums interrupt outdoor living.

Tighter protection without closing off the lanai

The denser weave creates a more effective small-insect barrier while retaining usable ventilation and outward visibility. It can also add modest daytime privacy. Because tighter mesh moves less air than 18×14 screen, panel placement and homeowner comfort should be considered before a full-cage installation.

  • 20×20 weave designed for most small flying insects
  • Useful for coastal and wetland-adjacent properties
  • Offers some daytime privacy while maintaining a view
  • Vinyl-coated fiberglass will not rust, corrode or stain

Professional screen planning

Mesh choice is only one part of a durable result. We also inspect the frame, spline channels, doors, panel spans and damaged fasteners before recommending repair or full pool cage rescreening.

No-see-um screen vs. regular pool screen

Regular 18×14 screen usually delivers more airflow and a more open view. No-see-um mesh is the better fit when tiny insects are the recurring problem. A site visit helps determine whether every panel needs the tighter mesh or whether targeted walls and doors will solve the issue with less impact on ventilation.

For an exact recommendation, we assess your enclosure in person and explain the tradeoffs before work begins. Contact Modern Pool Cage Painting for a free project estimate.

Good installation starts with the enclosure

  • Measure every opening and verify frame condition
  • Select mesh, spline and tension as a coordinated system
  • Plan door, lower-panel and roof materials by exposure
  • Finish with clean edges, even tension and a final inspection

Frequently Asked Questions

Clear answers about this screen option and how it fits a Florida enclosure.

Can no-see-ums get through regular pool screen?

Some very small insects can pass through a standard weave. A 20×20 screen reduces the opening size and improves protection.

Does 20×20 screen reduce airflow?

Its tighter weave moves less air than 18×14 mesh, although it still provides ventilation. Panel location and enclosure size affect the difference you feel.

Is no-see-um mesh good for an entire pool cage?

It can be, particularly in insect-heavy areas. Some homeowners prefer a mixed-screen plan that uses tighter mesh only on the most exposed walls.
