Selecting the appropriate mesh material is critical for durability and airflow. Fiberglass mesh is the industry standard due to its fire-retardant properties, UV resistance, and flexibility. For high-end or security-focused projects, Stainless Steel (304 or 316 grade) 'King Kong' mesh is preferred for its anti-theft capabilities and resistance to pet damage. Always verify the mesh density (e.g., 18x16 or 20x20 strands per inch) to ensure it effectively blocks small insects like midges while maintaining optimal ventilation.
