No one can match our experience and expertise in the installation of safety & security window films
Commercial Window Shield is one of the nation’s most experienced and trusted experts in safety and security window film installation. For nearly four decades, we’ve helped protect government buildings, schools, commercial properties, airports, museums, and some of America’s most recognizable facilities from glass-related injuries and damage.
As leading window film installers, we ensure every project meets safety standards and delivers long-term durability.
Commercial Window Shield specializes in large-scale security window film installation for government agencies, commercial office buildings, airports, schools, hospitals, and institutional facilities nationwide.
For nearly four decades, our work has focused on complex glazing systems, multi-story structures, curtain wall assemblies, and occupied environments where safety, logistics, and precision execution are critical. We understand the demands of high-profile buildings and security-sensitive facilities, and we execute every installation with strict attention to performance standards and long-term durability. Our experience extends across some of the nation’s most recognized public and private buildings, where professional-grade installation and risk mitigation are essential.
Security window film is a high-performance polyester laminate engineered to increase glass retention and reduce hazardous fragmentation during blast events, forced-entry attempts, and severe weather incidents.
Commercial-grade security films typically range from 4 to 21 mils in thickness and utilize advanced pressure-sensitive adhesive systems designed for high-impact performance. Depending on the building’s risk profile and glass configuration, films may be installed as standalone systems or integrated with attachment or wet glaze systems to improve frame retention and overall resilience.
When properly specified and professionally installed, security window film strengthens existing glazing systems without requiring costly glass replacement — making it a practical retrofit solution for institutional and commercial properties.
Effective protection depends not only on the film selected, but on the expertise behind its installation. Commercial Window Shield is experienced in executing security window film installations in:
Large-scale projects require careful coordination, phased scheduling, and the ability to work within occupied and security-sensitive environments. Our teams are accustomed to collaborating with facility managers, general contractors, and security personnel to ensure installations are completed efficiently, safely, and with minimal operational disruption.
From atriums and curtain wall systems to high-security interior glazing, we bring the experience necessary to manage complex installations at scale.
For facility managers and security directors, security window film is a risk-mitigation and occupant-safety strategy. It addresses one of the most common causes of injury during catastrophic events: flying glass shards.
Because it can be applied to existing glass systems, security film is frequently selected for retrofit projects where structural changes are impractical or cost-prohibitive.
Commercial Window Shield has specialized in glass protection since 1985. Following the evolution of modern blast mitigation film after the 1995 Oklahoma City bombing, we became early adopters of advanced security film systems and attachment technologies designed to improve glass retention during catastrophic events.
Our long-standing focus on safety, performance, and professional installation continues to position us among the most experienced commercial security window film installers in the United States.
Security window film significantly increases the shatter resistance of glass. While it cannot prevent glass from cracking, it keeps shards bonded to the film, reducing injuries and structural damage during impact events. Higher-mil films and attachment systems offer enhanced performance.
Films are applied directly to the interior side of the glass using a precision cutting and wet-application process. In high-risk environments, installers may add a wet glaze attachment system to anchor the film to the frame for greater blast resistance.
On April 15, 1995 a bomb planted by Timothy McVeigh in a rental truck detonated in front of the Alfred P. Murrah Federal Building in downtown Oklahoma City. The bomb blast killed 168 people and injured 680. A number of those killed and many of the injured were the result of flying glass shards from the federal building and buildings located blocks away. Security window films were developed soon after and have proved to be a tremendous success due to their shatter resistant capabilities.
Fragment retention films are generally thinner and used primarily to prevent minor glass breakage injuries. Security films are thicker, stronger, and designed for forced entry and blast mitigation applications.
The intention of the security window film is to hold the glass in place in the event of a bombing, gas explosion or foul weather event. But the security window film by itself won’t keep the window frame in place. By affixing the film to the frame with a wet glaze attachment system, you are protecting both the glass and the window frame.
After an increase in school invasions by armed intruders, the installation of security window film on all first-floor windows, doorways and other entry points became a critical part of the school system’s overall security plan.
