Retrofit external venetian blinds to improve daylight control and privacy at existing windows. WAREMA external venetian blinds can be configured for different façade details, installation spaces and drive concepts.

Retrofitting can be planned with front-mounted, self-supporting or other system variants, depending on the building. The product, fixing points, guidance and cover panel must be coordinated with the existing window and façade.

This page explains which external venetian blinds may be suitable and which details should be checked before installation.

In many projects, external venetian blinds can be added to existing windows. Feasibility must be assessed for the individual building.

Important planning points:

  • Available space for the slat stack, cover panel and guidance
  • Suitable fixing points and condition of the façade
  • Window dimensions, opening function and access for maintenance
  • Drive, power supply and control system

A qualified specialist can assess the installation situation and coordinate the product dimensions and fixing details.

Where new mains cabling would be difficult, WAREMA solar drives can reduce the need for a direct power cable to the unit. The solar panel, battery, system size and installation position must be matched to the project.
