No-See-um

Keep tiny biting insects out so you can enjoy your porch, patio, or pool enclosure in total comfort. Woven in the USA by Phifer, this specialized 20 x 20 micro-mesh fiberglass screening is engineered specifically for regions prone to no-see-ums, gnats, sand flies, and punkies.

While standard insect screening allows micro-insects to pass through, Phifer’s ultra-dense 20 x 20 grid weave creates an effective barrier against even the smallest pests while still allowing natural ventilation and fresh outdoor breezes to flow through. As an added benefit, the finer weave density provides enhanced daytime privacy from the outside.

Key Features & Benefits

• Maximum Biting Insect Protection: Ultra-tight 20 x 20 weave keeps out no-see-ums, gnats, sand flies, black flies, and mosquitoes that easily penetrate standard screen mesh.

• Ideal for Coastal & Marshy Climates: Essential protection for low-country, coastal, waterfront, and wooded outdoor living spaces, porch enclosures, and pool cages.

• Added Daytime Privacy: The denser mesh pattern creates a subtle screening effect that limits inward visibility during daylight hours without blocking your view looking out.

• Durable & Weather-Resistant: Woven from high-quality, UV-stabilized vinyl-coated fiberglass that won’t rust, corrode, dent, or unravel under salt air and harsh weather exposure.

• Flexible & Easy to Install: Pliable fiberglass construction handles easily around frame corners and rolls smoothly into screen channels.

Color Option

• Charcoal: Dark finish absorbs light reflection to reduce glare, delivering improved outward visibility and a clean, modern exterior aesthetic.

Frequently Asked Questions

What is the difference between standard fiberglass mesh and No-See-Um mesh?

Standard fiberglass mesh features an 18 x 16 weave, which allows airflow and stops standard flies and mosquitoes. The 20 x 20 No-See-Um mesh uses 4 extra strands per inch in both directions to stop tiny micro-insects like gnats and sand flies.

Does No-See-Um mesh restrict airflow?

Because the 20 x 20 weave is denser, airflow is slightly lower than standard 18 x 16 mesh, but it still allows pleasant natural ventilation while ensuring micro-pests stay outside.
