Ultra-Light Simplified Ventilation Cladding for Urban Façade Retrofits

Urban retrofits face mounting pressure to be lightweight, code-compliant, and quick to deploy—especially when dealing with low-rise buildings or modular refurbishments that cannot bear the weight or complexity of full insulation façades. In many such cases, thermal load and poor airflow inside these buildings persist due to exposed bare walls and stagnant interiors.

Jintong’s ultra-light simplified ventilation cladding targets precisely these challenges. The system consists of a perforated metal skin with variable airflow slots and sunshade geometries that wrap directly onto existing wall surfaces. It’s uniquely suitable for refurbishments on aged concrete or prefab modular shells that lack thermal breaks.

🔧 Engineering Context: Why Weight and Speed Matter

According to Building Science Corporation, the average load-bearing limit for retrofitted modular walls is under 9.2 kg/m². Most traditional cladding systems exceed this, while Jintong’s panels weigh as little as 5.3 kg/m² with integrated bracket kits. Additionally, a study published in ScienceDirect shows that metal ventilated façades with open-ratio >7% increase inner airflow efficiency by 31% in non-HVAC environments.

This makes it possible to deploy sun/vent façades on buildings where no other method would be feasible—like rooftop kiosk retrofits, mobile clinics, or decade-old municipal housing blocks.

🏗 Project Snapshot: São Paulo Healthcare Modules

In 2024, a retrofit of 64 mobile health stations in São Paulo utilized Jintong’s light cladding due to its fast install and airflow benefit. Originally constructed in 2001, these fiberglass + sheet-metal cabins lacked insulation, suffered overheating, and had roof condensation issues. After cladding:

• Interior ambient temp drop: 8.4°C (peak hours)

• Ventilation readings improved by 2.1x on vertical wall sections

• Patients reported comfort improvement in post-service surveys

The project received recognition in Architect Magazine and contributed to Brazil’s 2025 modular health station standard update.

💡 System Features

• Module width: 900mm or 1200mm per panel

• Perforation profile: 60° angled hex + micro-slot mix

• Back-cavity ventilation: up to 50mm airspace with clip-adjust kit

• Material: Zinc-magnesium coated steel or anodized aluminum
