Our new Lux external venetian blinds protect a building from overheating whilst optimising light or blackout. A robust system which cleverly retracts and tilts the blades with an integrated guide rail mechanism replacing the lifting strap of the traditional venetian blind. The blades are deeper too providing an overall stronger and more durable shading system. Operated by motor, the blinds cannot be lifted by hand thereby protecting the window and deterring a break-in into the building.
