Opti Essence Extruded Slats are non-insulated aluminium sections available in different sizes from 4 cm to 7 cm. They are from Granada aluminium sections and have a suitable thickness. These feathers are characterised by their strength and the possibility of painting them with all RAL and anodize colours. They are usually suitable for large sizes or in the event that customers wish to unify the colours of the shutter curtains with the colours of the windows and facades.
