Hardening Government Facilities with Safety Film
For government facilities, military installations, and state agencies, physical security is a paramount concern. While the primary discussion around window films often centers on energy efficiency, the U.S. Department of Energy (DOE) also recognizes the critical role of thicker films designed for security and safety [1]. Procuring security and safety window film rolls for maintenance stockpiles allows agencies to proactively harden vulnerable glass surfaces against impact, severe weather, and security threats.
Standard window glass is inherently fragile and can shatter into dangerous shards upon impact. Security window films mitigate this risk by holding the shattered glass together within the frame, providing an essential layer of protection for building occupants and critical infrastructure.
DOE Insights on Film Construction and Security
The DOE outlines the standard construction of applied window films, noting that they typically consist of an adhesive layer that sits against the glass, a polyester film layer, and a scratch-resistant coating [1]. However, when it comes to physical protection, the DOE explicitly states that facility managers can choose "thicker films that offer security" [1].
The Efficient Window Coverings Collaborative, an authoritative resource linked directly by the DOE, provides further technical detail. While standard solar control films are typically 2 to 7 mils thick (50–175 microns), films designed specifically for safety and security functions are substantially thicker [2]. These robust films are engineered to absorb impact energy and maintain the integrity of the building envelope even when the underlying glass is compromised.
Benefits of Stockpiling Security Film Rolls
For government procurement officers, purchasing safety and security film in bulk rolls offers several strategic advantages:
| Advantage | Description |
|---|---|
| Rapid Deployment | In-house maintenance teams can quickly apply security film to high-risk areas, ground-floor windows, or entryways without waiting for external contractors. |
| Cost Efficiency | Supply-only procurement of bulk rolls reduces the per-square-foot cost of materials and eliminates third-party labor markup. |
| Phased Upgrades | Agencies can systematically upgrade building security over time, prioritizing the most vulnerable facilities within their portfolio. |
| Dual Benefits | Many security films also incorporate solar control properties, providing both physical protection and energy savings by blocking UV rays and reducing solar heat gain [1] [2]. |
Integrating Security with Energy Efficiency
It is important to note that security upgrades do not have to come at the expense of energy performance. The DOE highlights that modern window films can combine multiple technologies. A thick security film can also feature tints, UV blockers, or low-emissivity (Low-E) coatings [1]. This means government agencies can simultaneously address physical security mandates and federal energy reduction targets with a single product.
By maintaining a stockpile of dual-purpose security/solar control film rolls, facility managers are equipped to handle broken glass replacements, security audits, and energy retrofits efficiently.

Frequently Asked Questions
How thick are security window films compared to standard films?
Standard solar control films are typically 2 to 7 mils thick. Security and safety films are substantially thicker, often ranging from 8 mils to 15 mils or more, depending on the required level of impact resistance [2].
Does the DOE recommend window films for security?
Yes. In its guidance on energy-efficient window coverings, the DOE specifically notes that consumers and facility managers can choose thicker films that offer enhanced security alongside other benefits like UV blocking and glare reduction [1].
Can security film also save energy?
Absolutely. Many security films are manufactured with solar control properties, meaning they can reject solar heat gain, block 99% of harmful UV rays, and reduce cooling costs while simultaneously hardening the glass against impact.
