Each of the WERS for screened ratings is the rating of a window system with a screen attached to the exterior of a window system (as energy rated by WERS). The ratings of screens are applied to the exterior of the window system and are only applicable to be rated covering the entire glass area.

  • The screen must be permanently fixed to the glazing system.
  • The screen must be of a woven screen or perforated screen type.
  • The screen must not be detachable, openable or removable, (egress security screens used to provide escape paths during fire are considered permanent screen systems).
  • The screen must be on the exterior of the window system.
  • The screen energy ratings can only be applied to a existing WERS rating.
