Drop and sliding arm awnings are ideal where you do not
have enough room above your window for a folding arm
awning, where you have a small window or where you want
to have greater control over shading on your windows.
With drop arm awnings the front profile lowers by
gravity and is fixed to side arms that fall from a pivot
point. The projection of the awning is therefore the
same as the distance from the roller to the pivot point.
This is the simplest form of awning that is ideally
suited to shorter drop windows. The arms normally fall
900 to the horizontal although they will drop through to
1350 to give shading against low angle sun.
To achieve a long projection or for clearance under the
arms, as would be required over a patio door, a sliding
arm awning is needed. In this blind the pivot point
moves up the slide as the blind drops. A spring
mechanism or gas piston device in the slides draws the
arm up, tensions the fabric and provides resistance to
wind buffeting.
There is an extensive range of fabrics available for
type of blind from plains to stripes and patterns. Many
fabrics have special coatings to make them resistant to
fading, water and staining.
These blinds are typically operated by a winding handle
linked to a gearbox fitted at one end of the blind or by
an electric motor
