Insect Screening

Keep bugs out of your space without blocking airflow or light. When choosing a screen, there are two factors that affect airflow and visibility: mesh size and wire diameter. The higher the mesh size, the smaller the holes. The thicker the wire diameter, the sturdier and tougher the screen.

These screens are made with materials that won’t corrode when exposed to weather.

Metal screens are stronger and more durable than fiberglass screens. They also hold up better against extreme temperatures. The wires won’t stretch, sag, or tear over time and have good visibility. Though, they’re less forgiving during installation compared to fiberglass screens, so they can get dented.

Aluminum

16 × 18—16 × 18 mesh size with a 0.011" wire diameter is the most common combination—it balances good visibility and airflow with durability.

Fiberglass

Fiberglass screens are easy to install because they’re flexible and won’t crease or dent. However, they tear and fray more easily than metal screens and can be damaged if exposed to harsh outdoor conditions.

16 × 18—16 × 18 mesh size with a 0.011" wire diameter is the most common combination—it balances good visibility and airflow with durability.

20 × 20—20 × 20 mesh size screens have such small openings that tiny insects, such as gnats and sand flies, can’t get through.
