FREQUENTLY ASKED QUESTIONS LAST UPDATED: MAR 2026

Yes, our Heroal stainless steel shutters are actually designed for everyday use, just like any other domestic shutter (heat/cold, light, noise, security). The difference is that these shutters have also passed stringent testing at the CSIRO to comply with AS1530.8.2 and AS3959:2018.

It’s never too early to commit us to your project and to lock in a price as material costs continue to rise. The earlier we receive a deposit, the less you’ll pay. In terms of construction, when the external walls are up, we can measure.

Yes, after commissioning we issue you with a BAL-FZ Compliance Certificate.

There’s a variety of exclusions that you can elect to make that can significantly decrease the overall price of your shutters. These include but are not limited to:  

  • Larger windows rather than more smaller windows
  • Making some shutters manual to save on the costs of motors
  • Combining windows so that one shutter can cover multiple openings saving money on installation and motor costs
  • Engaging your own electrician
  • Supplying your own UPS battery back up system

Heroal, the engineers of the stainless steel slats do not paint/powdercoat their slats due to:

– quality (delamination of paint)
– safety (harmful fumes in the protected area and the CSIRO stipulating painted slats are non-compliant)

In order to keep the shutter system we install on your home consistent with the compliant shutter we tested at the CSIRO, we are unable to paint the shutter slats.

137mm – 205mm – dependent on height, axle diameter, deflection and width.

Comfort Shutters made, fitted and tested the first compliant Heroal BAL-FZ shutter at the CSIRO.
