OKASOLAR F

Optimized Daylight System for the Façade

OKASOLAR F is a daylight system optimized for facades and unites the use of daylight with effective sun protection. The louvre type OKASOLAR F U reflects a large part of the solar irradiation to the outside. OKASOLAR F O is also retro-reflective and directs the incidental daylight deeply into the room. By combining both louvre types in one element, the requirements of the interior can be dealt with specifically.

OKASOLAR F can significantly lower the cost for artificial illumination and cooling loads and optimize the energy balance of a building. Due to the extremely narrow profile cross-section of the louvres, OKASOLAR F is especially well-suited for triple-insulating glazing and narrow pane build-ups.

High Functionality

  • Effective, direction-selective sun protection
  • Daylight direction towards building interior
  • Light transmission precisely and specifically adjustable to the project
  • No limitations in the function when compared to shading systems located in the interior or exterior
  • Two functionally different louvre types can be combined in one insulating glass module without visible differences
  • The extremely narrow dimension of the louvres enables especially narrow pane build-ups.
  • Fire protection according to requirements
  • Variety of special formats possible
  • Visibility as bird protection function

Sustainability

  • Daylight entry reduces need for artificial  light
  • Reduction of cooling load in summer, solar gains in winter time
  • Fully recyclable
  • Louvres fully and durably protected inside the cavity
  • No additional cost for maintenance, repair or cleaning

User Comfort

  • Comfortable daylight atmosphere in the entire interior
  • Outstanding vision to the outside
  • Effective privacy protection
