Shatterproof Shutters: Australia’s Impact-Resistant Protection
Exposed windows and shutters across Australia’s varied climates face constant environmental stresses like hail, windborne debris, and accidental human activities. Without advanced protection, these threats can destroy traditional glass and wood shutters necessitating expensive repairs. Thankfully, shutter technologies now exist that are virtually unbreakable. Shatterproof shutters shrug off intense impacts that would decimate ordinary materials. This durability better protects windows, interiors, and occupants.
This guide examines the latest material innovations and engineering features that make shutters highly impact resistant. It covers proper installation techniques for longevity, signs of damage indicating replacement, and how qualified shatterproof shutters defend households against both natural and manmade risks nationwide. Follow the recommendations below to protect what matters most.
Why Impact Resistance is Crucial
Windows and standard shutters are vulnerable to these common Australian threats:
- Hailstones traveling at over 60 km/hr in supercell storms easily fracture thin timbers and plastics.
- Cyclonic debris carried by winds over 200 km/hr can puncture conventional density materials.
- String trimmers and whipped cricket balls readily launch projectiles that crack ordinary glazing.
- Sports like golf involve hard objects that can shatter glass and split subpar woods.
- Children’s errant toys and balls plus deliberate vandalism.
- Accidental human collisions into windows and shutters.
Without advanced protection, these threats destroy standard shutters necessitating expensive repairs and replacement. Upgraded impact-resistant models prevent damage by:
- Absorbing, deflecting and dispersing impact forces over wider areas rather than a focused point.
- Employing highly ductile materials that flex and rebound without cracking or splitting.
- Using resilient multi-layered constructions including polymers, foams and films.
- Diffusing energy through break-resistant glass, flexible outer skins and cushioning inner cores.
Choose proven shatterproof designs using the latest high-tech materials wherever exposure risks exist.
Shutter Impact Testing Standards
Shutter producers utilize established testing standards to verify protection abilities:
ASTM E1996 / AS2047
This protocol assesses resistance to external windborne debris impacts likely in Australian storms. Methods include:
- Repeatedly striking the assembly with a 9 lb timber missile at 34 mph velocity.
- No tear-through or glass breakage is permitted after a specified high number of cumulative blows.
- Simulates typical debris speeds in cyclonic events up to 125 mph.
AS/NZS 4284
The Australian/New Zealand standard evaluates resistance to smaller hard-body intrusions:
- Impacts are made using a 0.5 kg metal ball bearing dropped from increasing heights.
- No star fractures in glazing or visible permanent damage to shutters are allowed to pass.
- Assesses suitability against vandalism.
Seek shutters certified to survive area-specific impact risks. Don’t settle for untested products.
Shatter-Resistant Shutter Materials
Material science advancements create remarkable impact toughness:
Multilayer Polymer Composites
- Usually a polymer or fiber reinforced skin bonded to an inner cushioning foam core.
- Absorb considerable force without permanent damage. Won’t crack like more brittle woods and masonry.
- Flex rather than shatter, bouncing back to retain strength after most typical impacts.
- Low-cost manufacturing using molds allows any shape.
Polycarbonate
- Extremely strong clear thermoplastic material related to shatterproof plexiglass.
- Highly ductile and flexible – it distributes and absorbs forces rather than fracturing.
- Multiple times the impact strength of comparably thick standard glass.
- Lightweight with UV protection added. Easy to shape, repair and replace.
Impact-Resistant Film
- Flexible transparent multilayered polymer sheets applied to glass surfaces.
- Disperse and dampen strike energy rather than transferring forces directly to glass panes underneath.
- Significantly boost glazing protection from debris, vandals, etc.
Advanced plastic technologies create remarkably damage-resistant shutters.
Impact-Proof Shutter Design Features
Strategic engineering further improves protection:
- Thermoplastic foam cores flex to absorb forces without permanent indentations. The resilient foam regains its original shape after most typical impacts.
- Hollow multi-walled internals compartmentalize and disperse kinetic energy from localized blows.
- Composite sandwich constructions separate and cushion outer skins from inner structures.
- Angled facades deflect blunt forces rather than receive perpendicular impacts.
- Reinforced sidewalls prevent flexural distortions spreading damage over large areas.
- Internal structural ribbing adds localized reinforcement at typical impact points.
- Robust frames with added thickness and gusseted mounting points resist shear loads.
Intelligently engineered designs complement ultra-strong materials for maximum shatterproofing.
Professional Impact-Resistant Installation
Correct installation optimizes shutter lifespan:
- Use extra-long fasteners into anchors suitable for the mounting substrate to securely attach fortified frames without loosening over decades.
- Position mounting hardware specifically at reinforced locations designated by the manufacturer. Don’t improvise attachment points.
- Seal perimeter gaps according to specifications without over-compression that could induce cracking.
- Avoid exposing shutters to conditions exceeding rated design limits. Consider security films if necessary.
- Handle panels carefully during installation to prevent scratches or edge impacts compromising strength.
- Follow all recommended hardware torques and mounting preparation requirements precisely.
Consult impact-resistant specialists to ensure shutter capabilities are maximized through proper installation. Never cut corners.
Signs of Shutter Damage Needing Replacement
Not all impacts will necessitate immediate shutter replacement. But visible indications consistently requiring swap out include:
- Any through-holes, fractures, splits or punctures in panel skins, frames or glazing. Even minor damage critically weakens overall integrity.
- Visible cracks or clouds within polycarbonate and acrylic panes. Surface scratches are acceptable if panel integrity is intact.
- Peeling, warped or lifted skins or edge liners evidencing delamination from inner cores.
- Severe dents and deformations over 3-5 mm deep. Damage spreads impact forces to adjacent areas.
- Any broken or dislodged reinforcing studs or ribs.
- Ripped out hardware indicating overstressed mounting points.
- Sagging, movement or detachment of frames from anchors.
- Difficulty opening and closing evidencing looseness.
- Noises during operation like cracking that indicates problems.
Consult manufacturers immediately if any concerning conditions emerge for professional damage assessment.
Matching Shatterproof Windows and Doors
For full protection also install:
Impact-Rated Windows
- Multilayered laminated or toughened glass tested to Australian Standards.
- Thicker glazing panels better disperse impact forces over areas.
- Polycarbonate and acrylic sheets offer increased strength.
Impact-Rated Doors
- Steel and composite doors with internal reinforcement and bracing.
- Heavy duty adjustable hinges secured firmly into solid framing.
- Multipoint locks tie door panels together resisting racking forces.
Security Screens
- Heavy gauge steel diamond mesh screens deter forced entry and vandalism when anchored properly into masonry.
Window Films
- Clear impact-resistant films like 3M Scotchshield to apply over existing glazing.
Upgrading all exterior barriers to match shutters provides comprehensive protection. Avoid creating any weak links negating shutters.
