Roof window roller shutter
What is a roof window roller shutter?
A roof window roller shutter is a roller shutter that is mounted on a roof window.
The term is used to distinguish it from roller shutters that move vertically. These are generally referred to as just roller shutters, as they are more common.
In contrast to vertical shutters, roof window rolling shutters have special features that differ in their technical design.
- A roof window opens outwards, i.e. into the working area of the roof window roller shutter. A vertical roller shutter is generally mounted in front of a window or door, opening inwards.
- With a vertical roller shutter, gravity is used to unroll the curtain, i.e. the roller shutter curtain. This usually is not possible with a roof window roller shutter, as the effect of gravity cannot be exploited due to the angle of the roof.
- Because it is installed on the roof, a roof window roller shutter is more exposed to the weather than a vertical roller shutter. In particular, snow remains on the roller shutter in winter, and freezing water can cause the curtain, i.e. the roller shutter curtain, to freeze.
Roof window roller shutters are also used outside the roof. Products of this type are generally used above skylight domes or in front of vertical windows or doors.
A roof window roller shutter positively influences some parameters, such as the energy transmittance or the sound insulation of a window behind it. However, the primary function is sun protection, i.e. shading the window behind it.
