Guardian Bastille installed 3M security window film at Citizens Bank branch locations across multiple states. As one of the largest retail banks in the Northeast, Citizens Bank operates hundreds of branches — each of which represents a potential target for smash-and-grab attacks, forced entry, and opportunistic break-ins. This portfolio-scale security window film program delivers consistent protection across the branch network without disrupting operations or altering branch appearance.
Glass Security Across a Large Branch Network
Retail bank branches face a consistent and well-documented security threat from glass attacks. Smash-and-grab incidents — where thieves break through glass to access ATMs, cash, or other valuables — are fast, difficult to prevent with traditional security measures alone, and can result in significant property damage and staff trauma even when no cash is taken. The glass at branch locations is a primary vulnerability that security teams must address.
Security window film changes the risk profile of glass attacks. When film-treated glass is struck, it shatters but holds together — the film holds glass fragments in the frame, requiring multiple sustained impacts to create a usable opening. That delay is often enough to deter an opportunistic attack entirely, or to ensure law enforcement response before entry is achieved.
3M Security Film Across the Citizens Bank Portfolio
The 3M safety and security film installed across Citizens Bank locations uses a multi-layer micro-bonded polyester construction that significantly increases the resistance of existing glass to impact and penetration. The film is virtually invisible once installed — there’s no change to the appearance of branch interiors or exteriors, which is critical for maintaining the professional, welcoming environment that retail banking requires.
Installation is performed on existing glass, eliminating the need for expensive and disruptive glass replacement. The cost-effectiveness of film over new security glazing makes it the practical choice for a large branch portfolio where consistent protection across dozens or hundreds of locations is the goal.
Multi-Location Coordination and Consistent Standards
Managing a security film program across a large branch network requires a contractor with the organizational capability to deliver consistent results at scale. Guardian Bastille coordinated directly with Citizens Bank’s facilities and security teams to develop a phased installation program — scheduling each branch location to minimize operational disruption, working during off-hours and weekends where required, and ensuring that every location received the same standard of installation.
Consistent quality across locations was a priority throughout the project. Guardian Bastille’s trained installation team applied film to the same specification at every branch, with consistent edge finishing and application quality regardless of branch size or window configuration.
Results: Portfolio-Wide Security Enhancement
The Citizens Bank security window film program has delivered consistent protection improvements across every treated branch location. Glass that was previously a primary vulnerability for smash-and-grab attacks now holds together on impact, significantly increasing the time and effort required to breach a window. The installation is invisible to customers and staff — branches look and operate exactly as before.
