How does aluminum sun shade cladding reduce solar heat gain?

Aluminum sun shade cladding, including horizontal louvers and vertical fins, intercepts direct solar radiation before it strikes the building envelope. The extruded profiles feature reflective finishes that bounce infrared energy away from the facade, reducing conductive heat transfer into the interior. By angling the louvers precisely, designers can maximize shading during peak sun hours while preserving sightlines and daylight penetration. Integrating the sun shades into the facade sub-frame ensures continuous rain protection and structural stability. The ventilated air space between the shading device and wall allows trapped heat to exhaust naturally, preventing radiant heat buildup. In atria or under deep overhangs, ceiling-mounted aluminum shades provide similar benefits for suspended ceiling systems. Overall, aluminum sun shade cladding enhances occupant comfort and cuts HVAC energy demand.
