Optimized Thin-Profile Perforated Cladding for Ventilation and Sunshade in Space-Constrained Façades

In ultra-dense cities, architects and engineers often face a critical design dilemma—how to incorporate proper ventilation and solar shading into wall systems when the available façade depth is severely restricted. Traditional systems for ventilation require ducts, plenum spaces, and insulation cavities; sunshades, in turn, protrude significantly from the wall surface. In many zoning codes—especially in Asian and European infill districts—such protrusions are restricted or banned entirely. This creates a bottleneck in achieving both thermal comfort and acoustic silence in buildings with facades under 100mm thick.

Jintong’s thin-profile perforated metal cladding system solves this problem by integrating airflow control and solar deflection into one ultra-slim panel. At only 68mm thickness, it delivers functionality normally expected from multi-layered systems. According to airflow performance simulations conducted by NREL and façade energy studies published in ScienceDirect, these claddings deliver up to 21% cooling load reduction in tropical urban environments. Additionally, acoustic suppression features allow designers to keep interiors calm even in high-traffic areas.

Here’s how the system works:

• Front face: 2.5mm aluminum with precision-cut perforations in thermal-deflective honeycomb pattern

• Mid-layer: Perforated steel baffles mounted diagonally to redirect hot air currents away from the wall cavity

• Back insulation: Mineral foam embedded with noise-reducing polymer granules

• Air-redirect fins: Pre-angled internal louver mesh blocks direct sunlight while allowing air diffusion

🏗️ Use Case: Urban Renovation - Osaka, Japan

A medical supply company needed to retrofit its side alley-facing walls without violating local 90mm overhang zoning codes. Their existing façade (concrete + tile) created oven-like conditions by mid-afternoon, which caused overheating and damaged sensitive supplies.

With Jintong’s slim vent panels installed:

• Peak surface temperatures dropped from 62°C to 35.8°C

• Interior humidity levels stabilized by reducing hot air entrapment

• Panel system required only 3 maintenance inspections in 2 years

Clients praised not only the performance but also the improved street aesthetics which helped brand their clinic visually. It’s now cited in Architect Magazine as a model for narrow thermal façades in medical buildings.

🔧 Other Applicable Scenarios

• Secondary sidewalls of mixed-use towers

• Portable testing centers requiring light cooling

• Hospital backup generator rooms with passive air intake

• Retail stores with alley-adjacent corridors

All these structures benefit from cladding that cools, breathes, and muffles—without protruding.
