1. Mesh Material: Like openable net windows, the doors are made from fine mesh fabric such as fiberglass, aluminum, or synthetic material. The mesh is tightly woven to allow airflow while keeping insects and pests out.

2. Frame Construction: The frames of openable net doors are usually made from lightweight and durable materials such as aluminum or PVC. These frames are designed to withstand frequent use and weather conditions.

3. Types of Doors: There are different types of openable net doors to suit various needs:

   • Hinged Doors: These operate similarly to traditional doors, swinging open on hinges.
   • Sliding Doors: Some net doors slide horizontally, which is useful in areas with limited space or where a hinged door might obstruct furniture or walkways.
   • Retractable Doors: These doors can retract into a housing when not in use, providing an unobstructed view and easy access.

4. Installation: Openable net doors can be installed on main entry doors, patio doors, or any doorway where ventilation is desired. They are often custom-fit to ensure they cover the entire doorway effectively.

5. Functionality: These doors allow for natural ventilation and airflow into the living or working space while preventing insects from entering. They typically feature user-friendly mechanisms like magnetic closures, spring-loaded hinges, or sliding tracks for smooth operation.

6. Benefits:

   • Insect Protection: They effectively keep out mosquitoes, flies, and other pests, promoting a more comfortable indoor environment.
   • Ventilation: They allow fresh air to circulate throughout the space, reducing the need for air conditioning and improving indoor air quality.
   • Natural Light: The mesh material allows sunlight to enter, brightening up interiors without compromising on insect control.

7. Maintenance: Similar to openable net windows, maintenance involves periodic cleaning to remove dust and debris from the mesh. Frames may need occasional lubrication or adjustment to ensure smooth opening and closing.

Overall, openable net doors are a practical addition to homes, offices, and other spaces where maintaining airflow while keeping insects out is desired. They contribute to comfort, health, and energy efficiency by reducing the reliance on artificial cooling and enhancing indoor air quality.
