Attackguard® and Prisonguard® Forced Entry Resistant Glass

It is security glazing designed to withstand sustained physical attack — axes, sledgehammers, hammers, crowbars, bricks, kicks — long enough to deter or delay an intruder. Unlike standard glass, it stays intact (or holds together in its frame) even after repeated blows from threats described in the Standard specified. It has been available and subject to continuous development since 1989.

No. They're tested to different standards for different threats. Bullet-resistant glass stops projectiles; forced entry glass resists blunt/sharp tool attacks over time. Some products are rated for both, but one rating doesn't imply the other.

It is tested and GenuinelyCertified™ to AS3555, UL 972 (burglary-resistant glazing), and EN 356 (P1A–P8B). Ratings are generally based on how many impacts or how much attack time the glazing withstands. It is also a safety glass certified to AS2208 and Z97.1

Laminated glass comprising two or more glass layers bonded with interlayers. In an attack, the interlayer holds glass particles together so there's no easy opening even when the glass cracks. If properly installed, an attacker would need to penetrate the glass-interlayer assembly. Prisonguard® does not incorporate polycarbonate, which has a propensity to embrittle with time, and to delaminate.

Depending on the Standard and the classification, from around 5 to 20 minutes of sustained attack. That delay is the point — most forced entry attempts are abandoned within a minute or two, and it buys time for security response.

From $600 per square metre and more, depending on the rating.

Often yes — either by replacing the glazing in existing frames if the frames are strong enough and wide enough to accept the glass.

No. Film improves ordinary glass and slows smash-and-grab attempts, but Prisonguard® withstands far more aggressive and sustained attacks. Film is a budget upgrade, not an equivalent.

Critically. An attacker can defeat strong glazing by pushing the whole panel out of a weak frame. Forced entry systems are tested as complete assemblies — glass, frame, and anchoring together.

Prisons, data centres, police stations, embassies, mental health facilities, hospitals, commercial buildings, petrol stations, storefronts and retail (smash-and-grab prevention), schools, government buildings, pharmacies, banks and increasingly homes — especially entry door sidelites and ground-floor windows.

It can be supplied flat or curved; clear or tinted or translucent or fluted; with integrated solar control to reduce SHGC; single laminate or in an IGU (insulated glass unit) to enhance thermal performance and/or sound attenuation; as a one way observation window; with anti-spall film applied to protect from glass shards.

Maximum panel height is 5000 mm and maximum width is 2700 mm for flat panels. Curved panels up to 3600 high x 2400 mm girth are available.
