DVA Mesh – One-Way Vision Privacy & Security Screen
Product Description
DVA (Diminished Vision Aluminium) Mesh is a specialized perforated/expanded aluminum screen for doors and windows that enables one-way visibility – occupants see out clearly, while outsiders cannot see in. Manufactured via precision expanded metal process, the unique “umbrella-shaped” louvered openings provide directional vision control, rain deflection, ventilation, insect protection, and structural security.
Combining the strength of aluminum alloy (0.5mm) with an optimized aperture geometry, DVA Mesh delivers a premium alternative to traditional insect screens, louvers, or solid shutters. It is widely used in residential security doors, office privacy screens, commercial storefronts, and architectural ventilation panels.

Key Features & Benefits
One-Way Privacy
Exploits light differential and directional aperture design: impossible to see in from outside during daytime, while maintaining clear outward visibility. Ideal for ground-floor homes, street-facing windows, and office partitions.
Rain-Deflecting Umbrella Holes
The expanded metal structure creates an overhang-like effect that prevents rainwater from blowing into the room, even with windows or doors left open for ventilation.
High Strength & Anti-Theft
Heavy-duty versions up to 0.5mm thickness offer far greater resistance to cutting, impact, and prying than standard insect mesh or plastic screens.
Ventilation + Pest Control
Optimized open area ensures continuous airflow while blocking mosquitoes, flies, rodents, and other pests without sacrificing privacy.
Corrosion-Resistant & Low Maintenance
Made from rust-proof aluminum alloy with powder-coated finish, it withstands humidity, rain, and UV exposure with minimal upkeep.
Lightweight & Easy to Install
Low density reduces load on door and window frames while remaining compatible with security doors, sliding windows, casement windows, fixed screens, louvers, and cladding systems.
Versatile Applications
Suitable for residential security screens, office privacy partitions, shopfront ventilation, balcony railings, decorative facades, and equipment ventilation panels.
See out, stay private, stop rain, block intrusion – DVA Mesh redefines your window & door protection.
