An external roller shutter is made of connected rigid slats, usually PVC or aluminium, that retract into a box installed in the window head. Small gaps between the slats provide a limited amount of daylight and ventilation and when fully extended provide a ‘block-out’ function.
Thermal comfort Overheating prevention | ***** | Reduces solar radiation up to 96 % (*) when fully extended. |
Thermal comfort Passive heating Insulation | ***** | Roller shutters provide an additional layer of insulation helping to keep warmth inside and reduce heating costs. How strong that effect is depends on the type of glazing behind it. |
Visual comfort Daylight | * | The gaps between the slats allow for a certain degree of daylight, but it will mainly depend on how much the roller shutter is retracted. In winter it allows maximum daylight when fully retracted. |
Night cooling Ventilation | *** | In combination with an open window, the gaps between the slats allow for a degree of ventilation, but it will mainly depend on how much the roller shutter is retracted. |
Wind resistance | ***** | Rigid slats guided by side channels can withstand strong winds. |
Operability | ***** | External roller shutters perform best when operated automatically, maximising energy savings and comfort. |
Maintenance | **** | Regular maintenance ensures the proper functionality and the life span of the product. |
Weather sensors adjust shading according to sunlight intensity, outdoor temperature and wind conditions.
Smart integration connects with building management systems (BMS) or smart home solutions.
Dynamic facades optimise both cooling in summer and passive heating in winter by managing solar gains automatically
