Evaluation FactorIntegrated BAL-FZ WindowsFZ-Rated Shutter Systems + BAL40 Windows
Primary BenefitAesthetics & Simplicity: Maintains the architectural design and requires zero user operation.Cost Efficiency: Generally a lower upfront capital investment for the product.
Operational ModePassive: Protective without human or mechanical intervention.Active: Requires physical or electronic activation to engage.
Visual ImpactNo change to building facade; larger glass spans are often possible.Visible guide tracks and pelmet boxes (approx. 250mm–300mm) above the window.
Light & VisionProvides natural light and progressive visibility during a fire event.Complete blackout: eliminates visibility to the outside once deployed.
MaintenanceStandard glass/frame maintenance.Periodic testing of motors, battery backups, and track lubrication required.
InstallationInstalled by the window contractor as a single unit.Coordinated install: Window supplier + Shutter installer + Electrician.
Power DependencyNone.Motorized versions require a fail-safe battery backup to operate during power cuts.
DurabilityHigh: No moving parts to jam or degrade over time.Moving parts subject to weathering; tracks must be kept clear of debris.

Considerations for Selection

Choose Integrated BAL-FZ Windows if:

  • The project prioritizes architectural intent and “clean” facades.
  • The home will be frequently unoccupied (e.g., a holiday home or commuters).
  • The owner wants to avoid long-term mechanical maintenance.
  • The views from the property are a primary feature of the home’s value.

Choose Shutter Systems if:

  • Upfront budget is the primary constraint for the build.
  • The windows are in low-visibility areas (e.g., laundry, bathrooms, or rear elevations).
  • The homeowner desires the added benefit of security and blackout privacy for daily use.
  • The building design can easily “hide” the shutter pelmets within the eaves or wall cavity.

Impact on Building Workflow

  • BAL-FZ Windows: One point of contact.
  • Shutters: Requires “flashing in” the tracks and coordinating an electrician to run power to every opening. Ensure your builder has accounted for the electrical and structural labor when comparing the total cost.
