To reduce heat loss through windows, the glazing, frame, installation and external shading all need to be considered. Lowered roller shutters can create an additional air layer in front of the window, while compatible sun shading solutions can be controlled to use daylight and solar gains when appropriate.
A study cited by the Industry Association for Roller Shutters, Sun Shading and Automation (IVRSA) reports that heating-energy effects vary by building and by the combination of windows and automated shading. Project-specific results therefore depend on factors such as glazing, orientation, air tightness and control strategy.
External venetian blinds allow the slat angle to be adjusted for daylight guidance and privacy. Compatible automated controls can position the shading according to configured schedules or sensor inputs; manual operation remains available where supported.
Up to 60% solar heat are allowed to enter when the sun shading is open (provided that modern heat protection glazing with a typical g value of 0.6 is installed).
Roller shutters can create an additional air layer between the window and the lowered shutter. This can reduce heat transfer through the window area, but the effect depends on the shutter, window, installation, air tightness and operating position.
A lowered roller shutter can create an additional air layer in front of the window; the resulting reduction in heat transfer depends on the window and shutter system.
