When a southerly change or summer storm hits Melbourne or Sydney, windows and doors take the first blow. Hail, debris and pressure shifts can quickly turn glass into a weak point. Shutters add a tough outer skin that absorbs impact and sheds water, reducing shattered glass and costly damage. Here’s how they help in wild weather—plus what to look for and simple tips to get storm-ready.

The storm threats your windows face

Storms attack in three ways: impact, pressure and water. Hail and debris strike at speed, cracking glass and frames, while gusts push and pull until weak points fail. Once a pane breaks—or seals deform—wind drives rain inside, soaking sills, plaster and floors. A well-specified roller shutter acts like a crash helmet: it absorbs the hit, spreads the force through slats and guides, and keeps rain out while the front passes.

What a roller shutter actually does in a storm

Closed exterior roller shutters form a rigid shield over the opening. Interlocking aluminium slats absorb hail impacts and spread loads through the curtain, guides and headbox, easing stress on the glass. If a pane does crack, the shutter helps retain fragments and keeps water out. It also sheds sideways rain like a “first roof tile,” protects seals from wind pressure, lowers storm noise and steadies indoor temperatures.

Which products help most—and where each one fits

Aluminium roller shutters are the frontline for larger windows and sliding doors. Foam-filled slats suit typical suburban storms; heavier extruded slats add stiffness for exposed sites (corners, coastal, hilltops). Robust security doors and window screens help at hinged doors and smaller openings, blocking wind-blown debris. Outdoor track blinds boost alfresco comfort but aren’t impact-rated for glass. Interior plantation shutters improve light control and insulation, but they sit inside—so they won’t stop hail.

Build details that matter when weather turns nasty

Slat profile & infill: Foam-filled aluminium slats offer insulation and everyday impact resistance; extruded slats deliver higher rigidity for exposed façades and large panes.
Side guides & bottom bar: Deep channels keep the curtain captured under wind load, while a solid bottom bar and positive locking help it stay down in gusts.
Finishes & fasteners: Quality powder-coating, sealed end caps and corrosion-resistant fixings maintain strength and smooth operation—especially near the coast.
Operation & backup: Prefer motors? Include a manual override or battery backup so you’re covered if the power drops.

Before the storm: simple prep that pays off

Close shutters early—before the first gusts arrive. Clear sills and tracks so water drains freely once the curtain is down. If you use smart controls, set a “storm scene” to drop street-facing and large panes first. Trim whipping branches and keep side guides free of debris. Do a seasonal check for loose end caps, worn straps on manual units or stiff motors so small issues don’t become big ones.

During and after: safe use and quick checks

Keep shutters down during the storm—don’t open them to “check the glass.” When it’s safe, inspect from the ground for dented slats, bowed guides or an uneven curtain. Minor dents are usually cosmetic; scraping or misalignment means it needs adjustment. If a unit jams, don’t force it—this can damage the axle or slats. Take photos for insurance and book a professional if you suspect frame or structural impact.

Roller shutters vs. double glazing: better together

Double or laminated glazing strengthens windows, but glass still takes direct hits and seals can be overwhelmed by wind-driven rain. A roller shutter adds a sacrificial, repairable layer that absorbs impact and diverts water before it reaches the pane. Many homeowners pair laminated glass with shutters on street-facing or exposed windows for the best blend of resilience, quiet and everyday usability.

Smart controls: helpful, if you set them up right

Automation is more than convenience in a storm. Timers or weather integrations can drop key shutters at set wind speeds or on a “closing cue.” Remote control via app is handy if a cell change pops up while you’re out. Test the manual override twice a year so you’re confident under pressure. Upgrading? Ask about quiet motors, obstacle detection and multi-channel remotes for smooth group control.

Maintenance that extends service life

Strong performance comes from small, regular habits. Wipe powder-coated surfaces a few times a year and keep drainage holes clear. Check manual straps and gearboxes for fray or stiffness; on motorised units, listen for sluggish starts that may signal misalignment or a tired motor. If a section is dented, ask about replacing individual slats instead of the whole curtain. A quick annual service before the wet season brings quieter operation and fewer surprises.

FAQs

Will hail damage my shutters? Severe hail can dent aluminium slats, but dents are usually cosmetic and the curtain stays functional—protecting the glass behind. Consider stiffer profiles on exposed elevations.

Are outdoor blinds enough for storm protection? They’re great for alfresco comfort, but not engineered as impact-rated barriers. Use roller shutters to protect glass.

Do shutters make my home too dark? You choose. Keep living areas open most days and close shutters for naps, evenings or when a front is forecast—smart controls make it easy.

What about bushfire zones? In BAL-rated areas, ask about fire-rated shutter options designed for extreme radiant heat while remaining practical day to day.

Bringing it all together

You don’t need to bunker down—just remove the “what if.” Shutters add a tough layer that takes the hit while boosting privacy, insulation and noise control. With the right profile, smart controls and simple upkeep, you’ll be ready for the next hail burst and more comfortable between storms. Want help prioritising openings?
