Rethinking Terrace Envelopes in Dense Urban Environments

As urban density increases, terraces become microclimate battlegrounds. These spaces suffer from solar heat gain, stagnant airflow, sound reverberation, and material decay. Traditional solid wall systems do little to mitigate these effects. Engineers are now turning to ventilated perforated sunshade panels—a solution offering thermal moderation, aesthetic enhancement, and acoustical improvement in a single envelope treatment.

Engineering Perspective: Thermal & Acoustic Behavior

From a thermodynamics standpoint, the ventilated cavity behind perforated panels acts as a buffer zone. This technique is validated by ScienceDirect thermal façade models showing a 9.7°C reduction in internal wall temperatures under solar load. Meanwhile, acoustic studies referenced by ASHRAE indicate noise attenuation of up to 18 dB when using micro-perforated aluminum backed by mineral wool.

Urban Case Example: Mixed-use Development in Kuala Lumpur

A 22-story high-rise in Kuala Lumpur incorporated Jintong's vertical-perforation ventilated panels on the terrace walls of floors 5–8. Previously, those walls radiated heat onto the terrace flooring, causing thermal discomfort and blistering. After installation:

• Surface temperature dropped by 6.3°C (peak hours)

• Sound levels from nearby highways reduced by 15%

• Tenant outdoor usage increased 2.6x over baseline

• Maintenance intervals extended by 18 months

Beyond Sun & Heat: Architectural Versatility

Aside from performance, architects use Jintong panels for design language. In a recent ArchDaily-published school project, panels created a dual-tone rhythm through alternating anodized bronze and charcoal finishes—framing student lounges and stairwells without sacrificing airflow. This level of customization is possible due to:

• Over 24 perforation patterns and custom-cutting via CNC

• Modular panel sizing to align with beam spacing

• PVDF and powder coating options for >15-year lifecycle

System Integration: Framing & Retrofitting Logic

Our panels integrate with most concrete, steel, or curtain wall backbones. Brackets accommodate offsets for fire escape clearance or planter installations. One client in Dubai retrofitted a 2010-built business center by anchoring Jintong’s system into existing hollow brickwork—finishing in 28 days without any structural modifications.

Technical Collaboration with Sustainability Experts

All Jintong systems support LEED v4 thermal comfort credits, and we’ve worked with consultants aligned to USGBC and Dezeen Design Network. We provide CFD airflow simulations and material submittal packages upon request.
