Security Film vs Security Screens in Adelaide — Which One Stops the Smash, Which One Stops the Climb

Security film and security screens defeat different threats. Security film, applied to the inside face of an existing pane and tested under AS/NZS 2208:1996, holds the broken glass together on impact — the smash-and-grab attacker breaks the pane, but the spalled glass stays bonded to the film and stays in the frame, which buys time and frustrates a quick-snatch entry. Security screens, tested under AS 5039:2008 and installed under AS 5040:2003, are a stainless-steel or perforated-aluminium mesh barrier installed over the opening — they prevent forced bodily entry through the window even after the glass is gone. Different standards, different test regimes, different threats. They aren’t competitors; on most security-conscious Adelaide homes they’re complements. This is the standards-led comparison. It explains what each product is, what each Australian Standard actually tests, and where the right answer is film, screen, or both.

This article sits below the AS/NZS 2208 heritage-glass pillar and complements the film mil-ratings explainer and the Grade A vs Grade B safety film article. Vista Fox installs security film and works alongside SA security-screen specialists where a combined solution is the right call. The honest answer for many homes is the combination, not the choice between.

The standards stack — different tests, different threats

The security-glazing conversation lives across two parallel standards stacks. They don’t overlap; they answer different questions.

For glass and applied film — AS/NZS 2208:1996 and AS 1288:2021.

AS/NZS 2208:1996 is the Australian/New Zealand Standard for safety glazing materials. It defines the pendulum-impact test — a 45 kg leather-covered weighted bag dropped from a defined height onto the test pane — and classifies glazing materials by the drop height they survive without producing cutting or piercing fragments. Grade A passes at the highest drop height; Grade B at a middle drop height. Architectural security film, when bonded to a single annealed pane to manufacturer specification, allows the assembly to pass the same test as a unit. The film holds the broken glass to itself; the assembly behaves as safety glazing.

AS 1288:2021 is the standard for selection and installation of glass in buildings — where safety glazing is required (doors, sidelights, low panels, wet-area glazing). AS 1288 is the document that tells you a particular pane needs to be safety glazing; AS/NZS 2208 is the document that tells you what counts as safety glazing.

The full safety-film position — including the manufacturer test certificate, the WFAANZ membership condition, the WERS for Film accreditation, and the AS/NZS 2208 compliance sticker affixed at install — sits inside the AS/NZS 2208 heritage-glass pillar.

For security screens — AS 5039:2008, AS 5040:2003, and AS 5041:2003.

AS 5039:2008 — Security screen doors and security window grilles — sets the minimum performance requirements for residential security screens. The standard specifies six tests:

• Knife-shear test — the mesh must not allow a defined blade to make an incision longer than 150mm
• Impact test — the screen must withstand a series of five impacts simulating kicking, shoulder-charge, or heavy-object attack
• Jemmy test — the screen must remain securely closed when a screwdriver or jemmy is levered between the screen and the frame
• Pull test — simulates an intruder attempting to pull the mesh out of its frame
• Probe test — applies 1.5 kN (≈150 kg) of deflecting force to each side of the opening, simulating an intruder attempting to deflect the screen enough to reach through
• Shear test — simulates a cutting-plier attack on the mesh

AS 5040:2003 — Installation of security screen doors and window grilles — specifies the installation method, fixing schedule, and minimum frame integration that lets an AS 5039-tested screen actually perform when installed in a building.

AS 5041:2003 — Methods of test — provides the test apparatus and procedure for the AS 5039 performance requirements.

A “security screen” that doesn’t carry compliance to AS 5039 + AS 5040 is a “fly screen with thicker mesh” — it stops insects, but it doesn’t stop a determined intruder.

The standards don’t overlap. AS/NZS 2208 tests what happens to the glass under human impact (anti-shatter, anti-laceration, hold-glass-together-after-break). AS 5039 tests what happens to a metal mesh barrier under forced entry (anti-cut, anti-knock-out, anti-deflect, anti-pull-through). They answer different questions about different products defending against different threats. Owners who reach for “security” as a single concept get the choice wrong; the standards-led owner asks “which threat am I defending against on this pane” and reads off the answer.

What security film actually does

Security film — also called safety film, anti-shatter film, or security window film — is a polyester (PET) film, typically 4 mil to 14 mil (100 micron to 350 micron) thick, bonded to the inside face of the existing pane with a pressure-sensitive adhesive. The film carries an AS/NZS 2208 test certificate from the manufacturer for specific film-grade and glass-thickness combinations.

What it does on impact:

• The pane still breaks. A thrown brick through a film-treated window still breaks the glass. The film does not make the glass unbreakable.
• The broken glass stays bonded to the film. Instead of falling out of the frame as a curtain of cutting fragments, the spalled glass adheres to the film. The film carries the broken-glass mass.
• The pane stays in the frame. Unless the impact also knocks the film off the perimeter (which is why high-security commercial work pairs film with a structural attachment system at the edge — Dow 995 wet-glaze sealant or a mechanical batten), the film and the broken glass stay in the opening.
• Time to entry is multiplied. A smash-and-grab raid on un-filmed glass is a one-second event. The same raid on a film-treated pane takes the offender 30 to 90 seconds of additional kicking, levering, and hand-clearing to make a useable opening — by which point the alarm has triggered, the dog is barking, the lights are on, the neighbour has heard, and the offender is moving on.

What it does not do:

• It does not stop the offender if they’re prepared to spend the time. With enough sustained attack and the right tools, any single-pane window will eventually yield. Film delays; it does not prevent.
• It does not stop bodily entry once the glass is cleared. A standard residential security film, after the glass is fully removed, does not stop a person climbing through the empty opening. The film holds the glass; it doesn’t replace the glass as a barrier.
• It does not protect against ballistic threats at residential film grades. Bullet-resistant glazing is a separate engineered product family, not a film retrofit.

The mil-rating drives the impact tolerance — see the film mil-ratings explainer for the 4 / 8 / 12 / 14 mil progression and which Grade each typically achieves. The Vista Fox default for residential security work is 8 mil, which achieves Grade A on most single-pane annealed assemblies per the manufacturer’s certificate.

The compliance documentation that should accompany every install: manufacturer test certificate (AS/NZS 2208), WFAANZ installer reference, WERS for Film accreditation where performance figures are claimed, and the AS/NZS 2208 compliance sticker affixed to the lower corner of each treated pane at install.

What security screens actually do

A compliant AS 5039 security screen is a stainless-steel woven mesh (304 or 316 grade) or a perforated-aluminium sheet, set in an aluminium or steel frame, with the frame fixed to the building structure to AS 5040 specification. The well-known Adelaide brands — Crimsafe, Invisi-Gard, Prowler Proof, Amplimesh, SecureView — all hold AS 5039 certification on their compliant product lines.

What it does on attack:

• Resists cutting. The 0.9mm to 1.2mm 316-grade stainless mesh on most premium products survives the AS 5039 knife-shear test and the cutting-plier shear test.
• Resists impact. The screen frame and mesh together survive five impacts simulating a kick or shoulder-charge attack without separation.
• Resists levering. The screen-to-frame connection survives the AS 5039 jemmy test — a screwdriver or jemmy bar applied at the edge cannot lever the screen out of the frame.
• Resists pull-through. The mesh-to-frame attachment survives a defined pull force.
• Allows airflow and visibility. The mesh is open enough to keep windows operable in summer (sliding sashes can stay open behind a screen) and to allow light and air through, while remaining intact against attack.

What it does not do:

• It does not stop the glass from breaking. A rock through a screen lands on the glass behind it. If the glass is unfilmed, it shatters. The screen prevents bodily entry but doesn’t prevent a thrown-object incident leaving glass on the carpet.
• It does not survive permanent removal. Determined attack with battery-powered angle grinders and saws will eventually defeat any screen. The screen, like the film, is a delay-and-frustrate measure; both rely on the offender’s risk threshold being exceeded before the barrier is fully defeated.
• It changes the look of the window. Even on the lowest-visibility products, a security screen is visible from the street and from inside. Owners on heritage frontages with conservation rules cannot always install screens on the front elevation.

AS 5040 installation matters as much as AS 5039 product compliance. A premium AS 5039 mesh installed with cheap fasteners into a softwood frame fails the AS 5040 fixing schedule and gives a false sense of protection. Owners should ask the installer for the manufacturer compliance documentation and the AS 5040 installation certification.

Where security film wins on its own

Five cases where security film alone is the correct answer, and a security screen would be wrong or impossible:

1. Heritage front doors and front-facing leadlight. A 1900s sandstone villa with original leadlight in the front door and adjacent sidelight cannot have a stainless-mesh security screen bolted across the front elevation — the heritage character is the asset. Security film achieves AS/NZS 2208 safety glazing without altering the visible appearance of the heritage glass. (See the Norwood heritage villa case study for the heritage application.)

2. Sidelights and fixed panels not designed to take screens. A narrow vertical sidelight beside a front door, a fixed panel above a stair, a feature window with no openable sash — these don’t have a frame configuration that an AS 5039 security screen can integrate with. The screen retrofit option doesn’t exist; film does.

3. Architectural panels where a screen is aesthetically impossible. Floor-to-ceiling glass on a contemporary entertainer extension, frameless glass balustrade panels, large-format feature glazing in a high-design build. A security screen would destroy the architecture. Film is invisible from inside and outside; the architecture survives.

4. Low-stakes ground-floor windows where a smash-and-grab is the realistic threat. A bathroom window, a laundry window, a small kitchen window — where the realistic risk is a quick smash-and-grab to reach in and unlatch a door, not a full forced entry through the opening. Film raises the cost of the smash-and-grab to the point where it isn’t worth the offender’s time, without the cost of full screening.

5. Commercial storefronts and retail glazing. A retail-strip shopfront where the threat is a ram-raid or a smash-and-grab at 3am. Heavy security film (12 mil or 14 mil) plus a structural-edge attachment system is the standard commercial answer — security screens at storefront scale are uncommon and aesthetically wrong for most retail. The same applies to commercial mixed-use ground floor.

Where security screens win on their own

Five cases where the screen is the correct answer and film alone is insufficient:

1. Sliding doors that need to stay open for airflow and pet access. A sliding patio door that stays open all summer for cross-ventilation and dog access. Film does nothing once the door is open. An AS 5039 security screen behind the open glass door delivers continuous protection while the slider is open.

2. Bedroom egress windows. A bedroom window that’s an emergency egress route under the building code. A film-locked broken pane does not provide a working egress; an openable security screen with a key-operable inside release does. Egress design favours the screen.

3. Outdoor entertaining areas with permanent open access. Bifolds, cavity sliders, large openable wall systems that are designed to be open most of the time. The security barrier is needed in the open-aperture position; film doesn’t operate there.

4. Insurance-driven full-perimeter requirements. Some insurance policies for high-value contents specifically require AS 5039 security screens on every accessible opening. The policy condition is the design driver; film alone does not satisfy it.

5. Areas with a documented forced-entry pattern, not a smash-and-grab pattern. Where the offending pattern is bodily entry through opened windows or kicked-in screens, not glass-smash, the screen is doing the load-bearing work. Film addresses the wrong threat.

Where you want both — and why most security-conscious homes do

Three cases where the right answer is film and screens:

1. Premium-east heritage homes with mixed risk. Film on the front-elevation leadlight (AS/NZS 2208 safety glazing on the heritage glass, invisible from outside, no façade alteration); security screens on the rear-elevation sliding doors and bedroom windows (AS 5039 forced-entry resistance on the openings that are the realistic entry point). The combination addresses both threats without forcing the heritage compromise.

2. Coastal and Hills homes with extended absences. Properties left unattended for parts of the year — holiday house in the Hills, second residence on the coast — benefit from layered defence. Screens on the sliding doors and accessible openings; film on the fixed glass and the high-value-contents elevations. Two-layer delay buys time the alarm system needs.

3. Insurance-stipulated combined coverage. Some commercial and high-value residential insurance policies recognise the combination — film on the glass plus screens on the openings — for premium reduction. The combination documentation pack (AS/NZS 2208 compliance sticker per pane plus AS 5039 screen certification per opening) is what the insurer requires for the premium adjustment.

The standard Vista Fox approach on a high-risk job: survey the elevations, identify which threats apply where, recommend film where film does the work, recommend a screen specialist where screens do the work, document both compliance regimes for the customer’s insurance file. The answer is rarely “film only” or “screens only” on a properly secured property.

Cost comparison — order-of-magnitude figures

Approximate Adelaide retrofit ranges, 2026 — film and screens are priced differently because the work is different:

• Security film, residential. 8 mil clear film on 5 to 8 standard windows: $1,800 to $4,500 typical depending on glass count, total area, and any frame work. The film mil-ratings explainer covers the mil-grade pricing progression.
• Security screens, residential. A full perimeter of AS 5039 hinged screen doors and window screens on a typical 4-bedroom home: $4,000 to $12,000+ typical depending on brand, frame size, and screen count. Premium custom-finish screens push higher.
• Combined film + screens, residential. Combined cost depends on the split — film on the heritage front elevation and feature glazing, screens on the openable rear elevation and bedrooms. Combined budgets typically $5,500 to $14,000+ on a heritage premium-east home.
• Pane replacement to safety glazing without film or screens. $400 to $1,500 per pane on standard residential glass; rapidly higher on heritage leadlight (often impossible — the original glass is irreplaceable). On a 12-pane front elevation, $4,800 to $18,000 of replacement cost vs $1,800 to $4,500 of film cost achieving the same AS/NZS 2208 safety classification without disturbing the heritage glass.

The cost crossover that matters most: on heritage stock with original leadlight, film is the only affordable AS/NZS 2208 path because replacement is either prohibited or prohibitively expensive. The film-vs-replacement maths is documented in the AS/NZS 2208 heritage-glass pillar.

Insurance and the security combination

Some Australian home and contents insurers acknowledge AS/NZS 2208 security film and AS 5039 security screens — separately or in combination — for premium reduction or for satisfying minimum-security policy conditions on high-value cover. The documentation an insurer typically asks for:

• For film: the manufacturer’s AS/NZS 2208 test certificate (Grade A or Grade B), the installer’s accreditation reference (WFAANZ), the AS/NZS 2208 compliance sticker affixed to each treated pane (with installer accreditation reference, install year, and unique reference number), and the WERS for Film performance certificate where applicable.
• For screens: the manufacturer’s AS 5039 compliance certification per opening, the installer’s AS 5040 installation certification, and the brand-specific warranty pass-through.
• For the combined package: both sets of documentation, a property survey identifying which protection applies on which opening, and (for premium high-value policies) sometimes an annual re-inspection.

We don’t make claims about specific insurer premium-reduction percentages — that depends on the policy, the insurer, and the address. We do provide the documentation pack that lets the customer have the conversation with their broker on solid evidence.

Frequently asked questions

Is security film as strong as Crimsafe?

They aren’t the same product and they aren’t tested the same way. Security film is tested under AS/NZS 2208 — a pendulum-impact test that measures whether a glazing material breaks safely under human impact. Crimsafe and other AS 5039 security screens are tested under a separate regime — knife-shear, jemmy, pull, probe, and impact — measuring forced-entry resistance through a metal mesh barrier. Film holds the glass together when the glass breaks; the screen prevents bodily entry through the opening. Both have legitimate roles; neither replaces the other on the threats it isn’t tested for.

Will security film stop a break-in?

Security film delays a break-in significantly — typically by 30 to 90 seconds of sustained attack on a residential pane — and frustrates a smash-and-grab pattern that depends on quick entry. It does not absolutely prevent a determined offender from eventually defeating the pane, especially with sustained tools. The combination of film with monitored alarms and exterior lighting is the realistic residential defence; film alone is one layer of a layered approach. For full forced-entry resistance through the opening once the glass is gone, an AS 5039 security screen is the next layer.

Do I need both film and screens?

It depends on what threats apply and on the building. Heritage front elevations where screens aren’t acceptable need film for the safety-glazing question; rear-elevation sliding doors where forced entry is the realistic threat need screens. Most security-conscious Adelaide homes end up with both — film on the heritage glass and feature panels, screens on the openable doors and bedroom windows. The Vista Fox survey identifies which threat applies where and which compliance regime answers it.

Will security film leave my window darker?

Most architectural security films are clear or near-clear. A standard 8 mil clear safety film transmits 80 to 90 per cent of visible light — visually similar to no film at all from inside. Where the customer wants additional solar or privacy benefit, a tinted security film is available, but it’s a separate spec choice from the safety classification. Clear film delivers AS/NZS 2208 without changing the look of the window meaningfully.

Does security film help with my insurance?

Often, yes — but the specifics vary by insurer and policy. The documentation an insurer typically asks for is the manufacturer’s AS/NZS 2208 test certificate, the installer’s WFAANZ accreditation, and the AS/NZS 2208 compliance sticker affixed at install. Some insurers also recognise the combination of film plus AS 5039 screens for high-value-contents cover. We provide the documentation pack on every install; the conversation with the broker uses our paperwork as evidence. Specific premium-reduction figures depend on the insurer and the property, not on a marketing claim.
