Visual glazing strips, also know as decal strips are required to fully glazed doors and surrounding glazing (including glazed walls with no transom i.e. mid-rail or similar) within common areas.

AS1428.1-2009 requires that visual glazing strips be a minimum 75mm wide, solid, non-transparent, contrasting line across their full width. The lower edge of line must be between 900mm – 1000mm from the finished floor level and must have a have 30% luminance contrast when viewed against floor or background surface within 2m of glazing.

It is highly recommended that frosted/translucent visual glazing strips are not installed on glazing and they still allow a level of filtered light through the glazing which does not meet the intent/purpose.
