Government buildings serve the public, which means many areas of government facilities are open to public foot traffic every business day.
Courthouses, city halls, and administrative offices need to remain accessible while protecting employees, visitors, and critical operations from a wide range of threats.
Balancing that openness with security requires a layered approach to government facility security, one that combines trained personnel, monitoring systems, access control, and physical hardening measures.
Because of their public role, symbolic importance, and the sensitive work that happens inside them, government buildings are more high-risk than many other types of facilities out there. That being said, they face many of the same threats as other commercial properties.
A layered approach to government facility security generally needs to address the following threats.
Whether the motive is vandalism, theft, or causing physical harm to those inside, forced entry is a major threat to government buildings. Any government building security plan therefore needs to implement measures that deter and prevent individuals from breaking in through doors, windows, or other glazed openings.
Civil unrest can turn government buildings into targets for rioters and looters, with mobs trying to breach entrances, smash windows, and generally force their way past security checkpoints and personnel. These events often develop quickly and can overwhelm facilities that are not prepared with adequate security barriers and protocols.
Active threats targeting government buildings can include armed intrusions, acts of workplace violence, and other deliberate attacks aimed at specific individuals or offices within the property. These situations demand not just deterrence but also barriers that physically slow down an attacker and buy time for those inside to react and wait for law enforcement response.
No single government facility security measure protects against all possible threats from every angle. That’s why it’s so crucial to layer security measures that combine people, technology, and physical barriers. If one layer is bypassed, there’s another behind it ready to keep protecting the facility and the people inside it.
Restricting who can enter a building and who can access specific areas within is a foundational component of any government facility’s security plan. This includes implementing credential-based entry systems, visitor check-in procedures, and verification of security clearances for staff working in restricted or classified areas.
Modern access control systems can log entry and exit activity, flag credential mismatches, and integrate with alarm systems to trigger immediate response to suspicious access or forced entry attempts.
Trained personnel remain one of the most effective deterrents available. Armed guards stationed at public entrances, restricted corridors, and high-traffic areas provide a visible security presence and a rapid response capability that technology alone doesn’t offer.
Security staffing decisions should take into account the size of the facility, the sensitivity of the work performed there, and the level of public foot traffic. For example, a city hall in a small town doesn’t need the same level of security personnel presence as a downtown courthouse in a major city.
Beyond stationing security personnel, having them perform regular patrols of the building perimeter and parking areas helps identify suspicious activity or individuals before they reach the entrance.
Pairing patrols with real-time monitoring of surveillance cameras and alarms tied to a central monitoring station gives government facility security teams the visibility needed to respond quickly to a forced entry attempt or breach anywhere on the property.
Even with strong access control, personnel, and procedures in place, a government building’s glass doors and windows remain a vulnerability.
The standard annealed glass found in many older buildings, and even the tempered safety glass found in modern facilities, breaks quickly under attack, whether that’s a blow from a hammer during a forced entry attempt, a thrown object during a riot, or a ballistic impact during an active threat scenario.
Forced-entry-resistant and bullet-resistant security glazing address this vulnerability directly, holding up against sustained attacks involving blunt force or ballistic impacts to keep threats out.
This type of glazing is commonly applied to exterior entryway glazing, such as glass doors leading to lobby areas, and ground-floor windows that are most exposed to street-level threats. It also has a role indoors when it comes to securing private offices, conference rooms, courtrooms, and other sensitive spaces. This mitigates risks even if an intruder makes it past the building’s exterior defenses.
One of the most common concerns with upgrading government property security is how to do it quickly and cost-effectively in existing buildings, especially those with outdated glass installed where a full glass replacement would be time-consuming and potentially disruptive to operations.
This is a particularly pertinent concern for historic government buildings, like courthouses and city halls, where preserving the original appearance and architecture matters as well.
The good news is that installing security glazing doesn’t have to mean tearing out existing windows and framing, even for historic buildings. Retrofittable framing adapters and compression-fit sub-framing systems allow forced-entry or ballistic-grade security glazing to be installed over the existing glass.
For example, Riot Glass J-Series sub-framing is ideal for hardening historic courthouses, creating access denial barriers over the original glass without drilling into or otherwise permanently altering the historic architecture.
A layered approach combining personnel, access control, monitoring, and hardened glazing can be applied across a wide range of government facilities, including:
Protecting a government facility against all the potential threats requires implementing multiple layers, from physical to procedural, that ensure if one layer fails, there’s another behind it to slow the threat down.
Government-grade security glazing plays a central role in this approach because it protects a facility’s most vulnerable glazed openings, preventing would-be intruders from bypassing security checkpoints and access control measures.
Riot Glass manufactures, supplies, and installs forced-entry-resistant and ballistic-grade security glazing suitable for government security applications right here in the USA.
Our team can help assess your building and its needs and recommend a solution that fits your facility’s specific risk profile and architecture.
Contact Riot Glass to discuss a security glazing plan for hardening your government facility that complements other essential government building security measures.
Yes. Compression-fit sub-framing systems allow forced-entry-resistant or ballistic-grade glazing to be installed over the existing glass while keeping original frames and architectural details intact.
Most facilities start with a threat assessment that identifies vulnerable entry points, gaps in access control, and areas that would benefit most from hardened glazing and other additional security measures.
No. Interior spaces like offices, conference rooms, and courtrooms often need their own hardening, especially where high-profile individuals may meet and work.
Forced-entry-resistant glazing resists repeated impacts from tools, thrown objects, and crowd pressure far longer than standard commercial glass, buying critical time for staff to secure the building and for law enforcement to respond.
Courthouses, city halls, and other facilities with high levels of public foot traffic and sensitive operations tend to have the most elevated risk levels.
Shopping centers, from outdoor strip malls to self-contained malls, are frequent targets of smash-and-grab theft, after-hours burglary, and other types of theft.
While traditional measures like surveillance cameras and alarm systems play an important role in overall shopping center security, they don’t do anything to physically prevent theft.
Cameras and alarms record events and alert security teams in real time, but neither one stops someone from putting a hammer through a storefront window or door and walking off with merchandise before anyone can respond.
This is why it’s crucial for shopping centers and businesses within them to look at hardening what’s physically standing between the sales floor and the parking lot or walkway outside: the glass itself.
Storefront glazing (glass) is typically the weakest point in an otherwise secure retail space. A shopping center tenant might have monitored alarms, a camera at every entrance, and a locked door after hours, and still lose thousands of dollars in inventory because ordinary commercial glass gives way in seconds to a single well-placed strike.
Upgrading that storefront glass with forced-entry-resistant commercial security glazing creates a barrier that can be virtually unbreakable, causing would-be intruders to abandon their attempts or get caught in the act.
Retail storefront design prioritizes visibility. Large glass panels showcase merchandise, invite customers in, and let natural light flood the space. This is all great for business, but it also means there’s a lot of exposed glass with relatively little separating the public walkway or parking lot from the merchandise inside.
A few factors compound the risks of smash-and-grab theft and burglary in shopping center settings specifically:
None of these factors are things retailers themselves have much control over, but what they can control is how much resistance their storefront glazing puts up.
Storefront security glazing, more specifically polycarbonate-based security glazing, is built to absorb and disperse impact energy instead of shattering. Depending on the specific product, this is achieved by laminating different combinations of glazing materials together.
For retailers specifically, the best forced-entry-resistant glazing solutions include polycarbonate in their compositions. For example, AP-Series glazing from Riot Glass, an ideal solution for retailers, is fully polycarbonate-based, with acrylics and other plastics mixed in to improve performance in certain ways.
Polycarbonate is favored for its incredible resistance to blunt-force blows. In fact, it’s virtually unbreakable under normal impact circumstances. A blow from a hammer or crowbar that would put a hole through a standard storefront window in one or two hits instead bounces off.
Polycarbonate shopping center security glazing maintains full visibility and natural light, so retailers gain peace of mind without sacrificing curb appeal. It also holds up against less dramatic threats, including accidental impacts, minor vandalism, and the wear that comes with being located in a high-traffic public space.
Because it can typically be installed over existing storefront glass as a retrofit, it’s one of the most practical, cost-effective ways for businesses located in shopping centers to beef up security, with minimal interruption compared to a full storefront replacement.
Security glazing is most effective as the centerpiece of a layered approach. A few complementary measures worth considering alongside it include:
Certain types of retail store layouts in shopping centers face unique challenges when it comes to layering security measures.
For example, some stores located within contained shopping malls don’t have glass across the full storefront opening, opting instead for a wide, mostly open entryway that allows an easy flow of foot traffic and air when open.
In such cases, an accordion-style or rolling shutter can cover the non-glazed width of the opening after business hours. These can be built with clear polycarbonate slats, essentially strips of the same kind of security glazing used elsewhere in the storefront.
This keeps the retail space visible through the shutter and lets ambient light through, rather than closing off the storefront behind solid metal, while still making entry harder for anyone trying to break in after closing time.
When used in tandem like this, security glazing and shutters aren’t competing solutions. The glazing protects the fixed glass areas 24/7, while the shutters add a second layer of defense for the hours when the store is unattended (or secure unglazed openings).
For shopping center owners and retail tenants, the first step towards increasing security to prevent forced entry, smash-and-grabs, and burglary is to identify which storefronts carry the most risk, and where those storefronts are most vulnerable.
High-visibility corner units, stores with particularly high-value inventory, and locations with a history of attempted or successful break-ins are typically the best candidates for a glazing upgrade.
From there, choosing the right security glazing for the shopping center’s storefronts comes down to the level of protection needed, the size and configuration of the existing storefront, and whether additional measures like shutters or grilles make sense for the space.
Riot Glass works with shopping center owners, security consultants, and individual retail tenants to evaluate storefront security and recommend glazing retrofit measures suited to the specific risks a given location faces.
Whether you’re concerned about smash-and-grab theft, after-hours break-ins, rioting and looting, vandalism, or anything in between, contact Riot Glass today to talk through your options and get a recommendation for your space.
No. It’s designed to look and feel like standard retail glazing and doesn’t significantly change a storefront’s appearance or the customer’s view.
Yes. In most cases, it can be retrofitted over the existing glass using specialized framing adapters without requiring full glass replacement.
It can. It’s designed to resist and significantly delay entry, rather than making it physically impossible. That’s usually enough to deter an intrusion attempt.
No. Smash-and-grabs can and do happen anywhere, and many shopping centers add glazing simply to reduce risk and lower potential losses regardless of their location.
City halls face a unique set of circumstances when it comes to security. They are open to the public by design, since residents need to pay bills, attend meetings, and access services, yet they also house sensitive records, council members, and staff, and can become flashpoints during civil unrest. That combination of open access and elevated risk makes city hall security a difficult problem to solve.
Fortunately, there are solutions that balance physical security with openness and accessibility, allowing city halls and similar government buildings to harden their security without hurting aesthetics or functionality. One such solution is a security glazing retrofit, which reinforces vulnerable windows and doors against threats without turning the building into a visibly fortified facility.
A security glazing retrofit involves installing a layer of impact-, forced-entry-, or bullet-resistant glazing directly over a building’s existing windows and doors, rather than removing and replacing the original glass and frames.
Specialized framing adapters hold the retrofit glazing in place by attaching around the perimeter of the existing window or door opening. These universal framing adapters secure the new glazing firmly in front of the original glass, creating a formidable barrier that can resist impacts, forced entry attempts, and even ballistic attacks, protecting the glass behind from shattering instantly.
This approach offers several major advantages for public buildings like city halls. It is generally faster to retrofit than to fully replace windows. It can often be done with minimal interruption to daily government operations, and it preserves the existing structure and appearance of the building.
For a facility that a city’s residents interact with regularly, keeping the familiar and inviting look of entryways and public-facing windows is key to maintaining the right kind of image. A city hall security glazing retrofit accomplishes the goal of hardening security without turning the facility into something that looks and feels like a fortress.
Now, what about city halls with architectural preservation concerns? Many city halls, courthouses, and other municipal buildings are historic structures, sometimes listed on state or national historic registries, with strict limitations on what can be altered, drilled into, or removed from the original facade.
Riot Glass addresses this with the J-Series compression-fit sub-framing, which was built specifically for courthouse hardening and similar applications.
Instead of drilling into frames, mullions, or surrounding masonry, the J-Series system holds security glazing in place over existing glass through compression, meaning the sub-frame exerts enough pressure against the existing structure to hold the glazing securely without the need for fasteners that penetrate original materials.
This is important for two reasons. First, it satisfies preservation requirements that would otherwise prohibit the kind of structural alteration a typical retrofit or window replacement requires. Second, it means the city hall security upgrade is effectively reversible. If the building’s needs change or a preservation review requires it, the system can be removed without leaving any permanent damage behind.
For a courthouse or city hall with ornate original woodwork, cast iron detailing, or protected masonry, that non-intrusive installation reversibility is often the deciding factor in whether a security upgrade is even possible.
City halls face a broad range of security threats, with many facing heightened risks over recent years as public buildings have increasingly become targets for attacks or flashpoints of unrest. Of course, not all threats are man-made, and city halls have to prepare for all the possibilities.
City halls often store cash from fees and payments, sensitive resident and government records, and IT infrastructure, all of which make them potential targets for break-ins and theft outside of business hours.
Municipal buildings are frequently symbolic targets during periods of civil unrest, and ground-floor windows and glass entryway doors are typically the first point of failure when a crowd turns hostile.
City council meetings, public hearings, and permit offices bring members of the public into close contact with elected officials and staff, and that access has the potential to be exploited by individuals intent on causing harm.
In coastal and storm-prone regions, hurricanes and severe windstorms turn ordinary glass into a serious liability. Wind-driven debris can instantly shatter standard annealed glass, sending it flying dangerously inwards, and once the building’s envelope is breached, the interior is exposed to further damage from winds and rains.
Each of these threats is unique, but they share one thing in common: standard commercial glass fails to protect against any of them.
Security glazing is tested and rated against specific threat types, from forced entry attempts using hand tools to ballistic impacts to blows from large windborne debris. By choosing the right retrofittable security glazing, city halls can harden their security against all the potential threats.
The core benefit of a city hall security glazing retrofit is that it addresses the full range of threats above with a single system that protects vulnerable glass doors and windows.
Against intentional attacks, whether that’s a break-in attempt, a riot situation, or an active threat, security glazing buys valuable time. Most forced entry attempts rely on speed, since an intruder trying to break through a door or window wants to get in before anyone notices or responds.
Forced-entry-resistant security glazing is designed to withstand repeated blows from common burglary tools and readily available objects, making a burglary or looting attempt much more difficult and time-consuming.
Ballistic-grade security glazing builds on this, resisting multiple rounds of gunfire from specific types of firearms and ammunition, which extends the window of time for building occupants to react, lock down, and shelter in place while law enforcement handles the threat.
Against storm damage, shatter-resistant windows and door glazing protect the original glass behind from flying storm debris, preventing shattering and keeping the building envelope intact to reduce the risk of cascading interior damage that comes along with a breached exterior.
Impact-resistant city hall security glazing also stands up to a variety of accidental impacts, helping protect the original glass from major damage and wear over time, making it a very cost-effective long-term investment.
City halls operate at the intersection of public access and public risk, and that makes them ideal candidates for security glazing retrofits.
Whether the facility is part of a modern municipal government complex or a historic building with strict preservation requirements, a retrofit can harden the city hall against forced entry, active threats, rioting, storm damage, and other threats without significantly altering its appearance or structure.

No. Retrofit glazing installs over the existing windows and other glazed surfaces, leaving the original glass and framing in place.
Yes. Compression-fit sub-framing systems like the J-Series system from Riot Glass hold security glazing in place without drilling into or altering the surrounding structure.
Depending on the glazing and its specific security ratings, it can protect against forced entry, ballistic impacts, storm damage, and other types of impacts and related security threats.
Not significantly. Retrofittable framing adapters are low-profile, and security glazing is crystal-clear, allowing the original windows or doors to show through and preserving the overall architectural look of the building.
Windows are one of the biggest sources of energy loss in any building. Heat escapes through single-pane or outdated glass in the winter, and unwanted heat creeps in during the summer, forcing HVAC systems to work harder than they should.
Insulated glass panels for windows, commonly known as insulating glass units or IGUs, were developed to solve this exact problem, and today they're a standard feature in commercial and high-end residential construction and renovations.
An insulated glass panel is made up of two or more panes of glass separated by a spacer bar and sealed around the edges. The sealed cavity between the panes is filled with air or an inert gas, most commonly argon, which acts as a buffer against heat transfer. Instead of one solid sheet of glass conducting temperature straight through, the IGU forces heat to cross an insulating gap before it reaches the other side.
The basic components of an IGU include:
Because the unit is fully sealed, the airspace stays free of moisture and debris for the service life of the product, which is what keeps the insulating performance consistent over time.
Additional panes of glass improve insulation, but the insulating gap is what really does the heavy lifting. Heat naturally moves from warmer areas to cooler ones, and glass on its own is a poor barrier to that movement. By adding a gas-filled cavity between two panes, an IGU slows the rate of heat transfer significantly compared to single-pane glass. That means less heat loss in the winter, less heat gain in the summer, and a building that holds a stable interior temperature with less strain on mechanical systems.
That being said, glass selection also plays a role. Low-E coatings, tinted glass, and laminated interlayers can all be incorporated into an IGU to further tune its thermal and solar performance, depending on the climate and orientation of the building.
The spacer bar deserves its own mention here too. Older insulated glass window panels relied on aluminum spacers, which conduct heat efficiently and create a weak point at the edge of the glass where condensation and heat loss are more likely to occur. Most modern IGUs now use warm-edge spacer technology, made from materials with lower thermal conductivity, which reduces that edge-of-glass heat transfer and helps the unit perform more consistently across the entire pane, not just in the center.
Note that standard insulated glass panels for windows use two panes of glass, while triple-pane configurations add a third layer and a second sealed airspace for even greater insulating performance. Triple-pane units cost more and add weight to the assembly, so opting for triple-pane usually comes down to climate severity and how much of a performance gain the building actually needs to justify the added cost.
Energy efficiency is the main benefit of an IGU, but it's far from the only one. A high-performance insulated glass panel brings a combination of advantages that a single pane of glass or an outdated double-pane window simply cannot match.
That last point is especially important when it comes to implementing insulated glass panels in schools, government buildings, and other facilities where both energy efficiency and security are part of the project requirements.
| Feature | Single-Pane Glass | Standard IGU | Security-Rated IGU |
| Energy efficiency | Low | High | High |
| Noise reduction | Low | Moderate to high | Moderate to high |
| UV/glare control | Depends on coating | Depends on glass | Depends on glass |
| Forced-entry/impact protection | No | No | Yes |
| Typical use case | Non-critical openings | General commercial/residential | Schools, government, high-risk facilities |
The right IGU configuration depends on the building's climate, noise exposure, and any security requirements specific to the facility.
Schools, government buildings, places of worship, and commercial properties in higher-risk areas often need more than energy performance alone, which is why more manufacturers now offer IGUs that combine insulation with a security-rated panel on one side.
Riot Glass offers this exact combination through its AP-Series IGUs, pairing standard insulating performance with integrated security panels and a full line of interior glass options.
If you're evaluating insulated glass panels for an upcoming build or retrofit, contact Riot Glass to discuss which configuration makes sense for your building.
An insulated glass panel, or IGU, is made of two or more panes of glass separated by a sealed, gas-filled airspace that reduces heat transfer and improves comfort and energy efficiency.
Yes. The multiple glass surfaces and sealed airspace help dampen sound transmission compared to single-pane or outdated double-pane glass.
Yes. Security-rated panels can be integrated into the attack side of an IGU, combining forced-entry or impact protection with the energy efficiency and sound mitigation of a standard insulating unit.
Yes. Riot Glass's AP-Series IGUs combine the energy efficiency and sound mitigation of a standard insulating unit with integrated AP25, AP375, or AP375-BR security panels, plus a proprietary Shock Spacer™ that protects the seal from impact.
It depends on the manufacturer and framing system. Riot Glass AP-Series IGUs, for example, are designed to work with the Riot Glass Universal Framing System for single and dual-pane upgrades.
