Are roller shutters good for security?

Roller shutters can improve window security by adding a visible physical barrier, but no shutter can guarantee that a break-in will be stopped. Product construction, guides, bottom rail, locks or anti-lift design and installation all matter.

What good security shutters add:

• Physical resistance. The curtain, guides and bottom rail make the glass less directly accessible. Compare the complete system rather than assuming every aluminium shutter is a security-rated product.
• Visibility and privacy. A closed shutter hides the interior and creates an obvious extra obstacle. Keep in mind that permanently closed shutters can also advertise that a home is vacant.
• Anti-lift features. Ask how the proposed design resists lifting and whether any locks engage automatically or require manual operation.
• Documented performance. If the salesperson claims impact, cyclone, bushfire or security performance, request the test report or certification for the exact complete system and installation method.

For maximum security, look for:

• a clearly identified slat, guide, bottom rail and locking specification
• suitable fixings for the wall and opening
• safe emergency operation during a power failure
• written product and workmanship warranties with local service support

Treat shutters as one layer alongside suitable door and window locks, lighting, alarms or cameras where appropriate. Do not block a required escape route without discussing emergency egress. Ask your own insurer whether the installation changes the policy or premium rather than relying on a sales promise.
