Electric Roller Blinds fitted in Hampshire. We have just installed 3 full cassette electric roller blinds into a property in Fareham, Hampshire. Our client recently had bifold doors installed and wanted a screen fabric to filter the daylight better. We manufactured electric roller blinds in a rounded cassette and had it specially painted Anthracite the same colour of the bifold doors, we hard wired into 3 fused spurs so no wires could be seen.
