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.
