KAFD Tower 3 Financial Center
Dynamic Motorized Kinetic Louvers & 4.0mm High-Tensile Solid Aluminum Curved Spandrels engineered for extreme desert thermal cycles.
14,200 m² Dynamic Kinetic Louvers + 8,500 m² CNC Deep-Drawn Spandrels.
Peak solar heat gain reduction. Maintained overall tower SHGC at 0.14.
ASTM E330 Ultimate proof load rated against extreme Arabian desert squalls.
Non-combustible rating coupled with CWCT 1,200 Pa Air / 600 Pa dynamic water barrier.
South-Facing Glazing Protection Array
Dual-skin aerofoil louvers dynamically positioned at 37° incident angle.
Hyperboloid 4.0mm Roll-Bended Edge
Sunset Tracking Mode Active
KAFD Tower 3 Curtain Wall Hoisting
Field alignment of motorized kinetic louvers and curved spandrels under 50°C solar radiation.
Surviving 52°C Ambient Thermal Shock & Severe Desert Sand Abrasion
Riyadh's desert microclimate presents one of the most punishing structural envelope testing grounds globally, demanding multi-layered structural and chemical defenses against heat, UV, and particulate erosion.
Extreme Thermal Shock (+52°C Desert Microclimate & UV Degradation)
Thermal cycling causes intense differential expansion between glass substructures and aluminum mullions. Engineered expansion joints and continuous EPDM isolating thermal bridges absorb cyclic expansion without oil-canning or fastener fatigue.
Kinetic Dual-Skin BMS Automation Integration
ALUMAX synchronized motorized kinetic louvers into KAFD's central automation bus. Intelligent sensors dynamically trim aerofoil blade deflection in 0.5° increments based on solar azimuth, cutting peak solar thermal gain by 34.2%.
Hyperbolic Sandstorm Abrasion & Micro-Scratch Resistance
High-velocity particulate silica winds erode standard coil coatings. We engineered a bespoke 3-coat PPG Duranar XL fluoropolymer formulation loaded with ceramic microspheres, sustaining gloss and zero blistering past 4,000 hours of cyclic ASTM testing.
