There are two common options.
- Roller shutters that are metal, are secured in a side track and have an automated mechanism at the top of the opening to roll up the shutter when not in use.
- External hinged shutters (plantation shutters) manually opened and closed, with fixed louvres or adjustable louvres.
If you require security, for either option the shutters need to be securely installed. The shutters and installation requirements will need to comply with the applicable Australian Standard, EG AS5039/5041.
Depending on your state there may be additional requirements to be met re the sale and installation of security equipment.
Depending on design roller shutters are typically marketed as providing insulation benefits, and noise reduction. They also block light and ventilation as a consequence.
Deciding your priorities and needs for convenience might point towards a particular design option. It’s also worth considering that systems designed to secure a property can work against occupants in the instance of the need to escape. EG house fire, flood etc. Our choices have put escape ahead of security.
