This ventilated perforated metal cladding and sunshade system is designed for suburban home extensions seeking functional performance, comfort, and aesthetic harmony. With a focus on controlling heat gain, improving façade durability, and minimizing maintenance, this solution transforms two-storey residential upgrades into high-performance architecture.

System Features:

• Sunshade Component:
  • Powder-coated aluminum horizontal fins
  • 220–230mm projection to meet planning constraints
  • Spaced at 600mm centers, matte graphite finish
  • Sized using sun-path analysis for maximum effect

• Ventilated Cladding Panels:
  • Perforated aluminum, 1200mm × 3000mm size
  • 24% open area for balanced airflow/light filtration
  • Mounted on clip-lock rails, 45mm rear ventilation cavity
  • Base inlet grille + parapet vent ensure static airflow path
  • Anti-corrosion finish resists pollen, dust, leaf debris

• Thermal Results:
  • Surface façade temperature drop: ~6.5°C
  • Indoor afternoon temps cut by 4–6°C in upper living spaces
  • HVAC runtime reduction: 18% in rear extension zone
  • Passive airflow + shading synergy verified via simulation and thermography

Homeowner Benefits:
🏠 Cooler interiors in west-facing rooms
💧 No repainting needed—just annual rinse
🧱 Panels blend with original structure while signaling modern design
🔧 Minimal site disruption with prefabricated modules
🧰 Installable without scaffold for most single-home sites

Installation Notes:
• Use thermal simulation during design
• Prefab panels to grid dimensions
• Commission with infrared imaging to verify surface performance
• Follow RICS and ArchDaily best practice for façade maintenance
