Howdens Joinery

Large format electric roller blinds with printed images


To supply and install 12no large electrically operated with blackout fabric and high resolution printed image.


  • Fabric must be made from one single piece, no joins or welds. Fabric must be blackout with matt finish and FR

  • A high quality image must be printed on the fabric

  • The electric roller blinds must be controlled externally by AV company, using hard wired control

  • The electric motors must rise and fall at a set speed to co-inside with the presentation speech

  • There must be a twin motor system with one to operate the blind and a second dormant backup motor available for instant operation should the first motor fail to operate

  • Must be a manual back and override

  • Black powder coated cassette frame to enclose inner workings


The majority of this project required bespoke elements. Firstly, the instant backup motor operation was very difficult to overcome. The majory of motors do not come with a clutch therefore if a motor fails, the roller tube would lock in position. A secondary motor would not be able to operate without a clutch system to allow the failed motor to free-wheel and the second backup motor to take over the drive.

The addition of an extra manual override was even more difficult to overcome.  The end result was a mixture of clever manual engineering with cable operation linked to the back of each set, with one person on standby at each of the twelve sets, ready for the unlikely failure of not one, but two motors!
