1. Basic Concepts of Insect Mesh
A window screen is a protective device installed on doors and windows to prevent insects, dust, and airborne debris from entering indoor spaces while maintaining air circulation and natural light exposure.
Window screens are commonly woven using different techniques, such as:
- Plain Weave
- Twill Weave
- High-Density Weave
The weaving method directly affects the insect-proof performance and breathability of the screen.
2. Primary Materials of Insect Mesh
The material of a window screen determines its durability, protection level, and breathability. The most common materials include:
Material | Features | Best Application |
---|---|---|
Fiberglass Mesh | Affordable, corrosion-resistant, excellent light transmission | General insect and dust protection |
Stainless Steel Mesh | Strong security protection, high corrosion resistance, expensive | High-security homes |
Aluminum Mesh | Lightweight and durable, but may oxidize over time | Standard window and door protection |
PVC-Coated Mesh | Flexible, resistant to deformation, excellent waterproof performance | Humid environments, such as bathrooms |
Polyester Mesh | Lightweight and economical but less durable | Temporary screens |
Different materials are suited for different environments. Choosing the right screen requires balancing living conditions, budget, and intended use.
3. What Is Mesh Count?
Mesh count refers to the number of holes per inch (2.54 cm) in a window screen. For example, a mesh count of 18ร16 means that there are 18 vertical threads and 16 horizontal threads per inch.
Common Mesh Counts and Their Applications
Mesh Count | Breathability | Protection Level | Best Application |
---|---|---|---|
14ร14 | High breathability | Low protection | Rural areas, well-ventilated spaces |
16ร16 | Moderate | Standard protection | General household insect control |
18ร16 | Lower breathability | Good protection | Residential communities |
20ร20 | Low breathability | Stronger protection | High-insect-density areas |
22ร22+ | Very low breathability | Superior protection | Dust/pollen prevention, laboratories |
๐ก The higher the mesh count, the smaller the openings, resulting in reduced airflow but enhanced protection against insects and dust. Choosing the right balance between ventilation and protection is key!

4. Chinese Standard vs. American Standard Window Screens
Comparison | Chinese Standard (GB) | American Standard (ASTM) |
---|---|---|
Regulatory Standard | GB/T 17492-2011 | ASTM D3656, DPP |
Common Mesh Sizes | 16ร16, 18ร16, 20ร20 | 18ร16, 20ร20, 22ร22 |
Calculation Method | Mesh Count = Number of openings per square inch | Mesh Count = Number of openings per square inch |
Material Selection | Fiberglass, aluminum, stainless steel | Primarily fiberglass, some aluminum in certain regions |
Application Scenarios | Residential homes, public buildings | Residential homes, commercial buildings |
๐ American standard screens are generally designed for enhanced protection, especially in pollen and dust filtration. Chinese standard screens are more tailored for daily household use.

5. How to Choose the Right Window Screen?
โ For general households: Choose 16ร16 or 18ร16 fiberglass mesh, offering a balance of mosquito protection and ventilation.
โ For high-insect-density areas (e.g., near lakes or wetlands): Choose 20ร20 or higher, which effectively prevents small insects from entering.
โ For security purposes: Choose 304/316 stainless steel mesh, which is impact-resistant and difficult to break.
โ For pollen/dust prevention: Choose 22ร22 or higher high-density mesh, which effectively filters out fine airborne particles.
โ For humid southern regions: Opt for stainless steel or fiberglass mesh, prioritizing mosquito prevention.
โ For windy and dusty northern regions: Choose high-mesh-count reinforced screens, which also help block dust.
โ For premium needs: Consider nano-coated mesh, which enhances stain resistance and UV protection.

7. Maintenance and Key Considerations
๐งน Cleaning: Regularly use a soft brush or vacuum to remove dust; wipe with a damp cloth to prevent buildup.
๐ก๏ธ Rust Prevention: Stainless steel screens should be kept dry and avoid contact with acidic or alkaline substances.
๐ Replacement: If you notice damage or aging (such as fiberglass screens turning yellow), replace them promptly.
