High-Performance Cladding for Sun and Vent Control on Bare Wall Buildings

Architectural renovation and construction in warm climates often deal with a common challenge: how to ensure effective thermal and airflow regulation in structures that were originally built without wall insulation. Bare wall buildings—ranging from pre-2000 concrete skeletons to rural prefab housing—lack both thermal buffers and airflow pathways. This results in significant solar gain, heat storage, and air stagnation that raises interior temperatures and damages both material and comfort levels.

Retrofitting these structures with traditional foam or mineral insulation is often impractical or too costly due to structural limits, space constraints, or preservation laws. That’s where Jintong’s metal perforated cladding system steps in: a modular, ultra-light assembly designed to serve as both a passive air ventilation and solar shading solution for bare-wall buildings—without insulation layers.

🔍 Technical Assembly Breakdown

• Ventilated substructure (40mm): mounted using low-profile Z-channels that allow vertical air drafting

• Perforated sunblock panels: 2mm powder-coated steel with 8% open area optimized for high-sun-angle shading

• Convection flow deflectors: embedded mesh guides that prevent air stagnation while enhancing updraft

• Custom color coatings: optional reflective finish to reduce radiant gain by up to 35%

This design is certified under ASHRAE 90.1 ventilation modeling protocols and validated in tropical passive cooling field tests by NREL.

📘 Real-World Application: Factory Wall Retrofit – Durban, South Africa

A plastic molding facility located in Durban’s industrial zone reported extreme heat stress in the warehouse zones closest to the exterior non-insulated tin wall. Temperatures reached 43°C by 3PM daily in summer.

After installing Jintong’s modular airflow cladding:

• Interior temperatures dropped by 10.2°C in the first week

• Employee sick leave due to heat-related fatigue decreased by 23%

• Factory energy use fell by 18% due to reduced cooling load

This success led to a wider municipal retrofit program, now listed in ScienceDirect’s publication on tropical zone retrofits.

🏗️ Applicable Structures

• Steel-clad warehouses and storage units

• Concrete slab-built public offices lacking insulation

• Rural clinics and mobile labs with zero cavity walls

• Community centers constructed with cost-minimal walls

As shown in a 2024 report from Building Science Corp, integrating breathable cladding with solar blocking yields up to 27% improvement in year-round thermal consistency in uninsulated walls.
