Guardian Bastille installed 3M security window film at WSFS Bank locations across the Mid-Atlantic region. Banks and financial institutions have specific security requirements that go beyond standard commercial window film — the glass at branch locations must be able to withstand forced entry attempts, accidental impact, and in some cases blast events, while still meeting the aesthetic standards of a customer-facing retail environment. 3M security film meets all of those requirements.
Why Banks Specify Security Window Film
Glass is one of the most vulnerable points in any bank branch. Standard float glass shatters easily under impact — whether from a forced entry attempt, a smash-and-grab, or an accidental collision. When glass fails, it creates immediate safety risks for staff and customers and leaves the building exposed until emergency repairs can be made. Security window film changes that equation.
3M security film holds glass fragments in place when a pane is broken, significantly slowing forced entry and reducing the risk of injury from flying glass. For a bank branch where staff are present and cash is on the premises, that delay matters. It increases the time required for a break-in and reduces the likelihood that an opportunistic attack will be successful before law enforcement responds.
3M Safety and Security Film at WSFS Bank
The 3M safety and security film installed at WSFS Bank locations is designed specifically for high-security commercial applications. It uses a multi-layer micro-bonded polyester construction that dramatically increases the resistance of existing glass to impact and penetration — without changing the appearance of the windows or requiring glass replacement.
For bank branches, this is a critical advantage. Glass replacement is expensive, disruptive, and time-consuming. Security film is applied to existing glass at a fraction of the cost and can be installed during off-hours with no disruption to branch operations. The finished installation is virtually invisible — there’s no change to how the branch looks from inside or outside, which is important for maintaining the professional, welcoming appearance that retail banking requires.
Multi-Location Installation Across the Mid-Atlantic
WSFS Bank operates branches across Delaware, Pennsylvania, New Jersey, and Virginia. Managing a security window film program across multiple locations requires a contractor who can deliver consistent results across different building types and window configurations — and who can coordinate installation at active banking locations with minimal disruption to operations.
Guardian Bastille managed the full scope across the WSFS portfolio, working with the bank’s facilities and security teams to schedule installation at each branch. Work was performed during off-hours and weekends where required to ensure branches remained operational throughout the project. Every location received the same standard of installation, with consistent film selection and application quality across the entire program.
Results: Enhanced Security Across the Branch Network
The 3M security window film installation across WSFS Bank locations provides continuous, passive security enhancement at every treated branch. Glass that was previously vulnerable to smash-and-grab attacks now holds together on impact, slowing forced entry and reducing injury risk from flying shards. The installation is completely transparent to customers and staff — there’s no visible change to the branch environment.
Security film also provides UV protection and modest solar heat reduction as secondary benefits, improving comfort at teller windows and in customer-facing areas near glass.
