Install external sun shading

← Back to Cool Tips Pro Building & Infrastructure

External blinds, awnings, brise-soleils, and shutters intercept solar radiation before it passes through the glass. That makes them significantly more effective than indoor shading, which only acts once heat has already entered the room.

Once heat passes through glass, it gets trapped inside (a greenhouse effect). Blocking radiation outside the building — with blinds, adjustable louvers, or awnings — stops that trapping at the source.

• Far more effective than indoor curtains or blinds
• Sharply reduces the need for daytime air conditioning
• Adjustable models let you keep natural daylight
• Also improves visual comfort by cutting glare

1. Identify the most exposed facades (south- and west-facing first)
2. Choose the right shading type: retractable awnings, fixed or adjustable louvers, shutters
3. Favor motorized models with automatic control based on sunlight
4. Have them installed by a professional to ensure wind resistance
5. Train staff on usage — close them before the heat peaks, not after
