Case Study: Colorado's Largest School Security Film Project — 3M Scotchshield & Epic Security

In what is believed to be the nation's largest school security film project, a prominent Colorado school district serving more than 53,000 students across 70 schools in 8 municipalities completed a district-wide installation of 3M Scotchshield Security Window Film S2400 with the 3M Impact Protection Attachment (IPA) system. The massive undertaking — led by Epic Security & Architectural Window Films, a multi-year 3M National Dealer of the Year — represents a milestone not just for Colorado but for school security nationwide. This case study examines the scope, product selection, field testing, and installation of a project that sets a new standard for district-wide glass hardening at scale.

Project Overview: A Landmark Colorado School District

District context: This prominent Colorado school district spans 8 municipalities and serves over 53,000 students — making it among the largest in the state. The district boasts a 91% graduation rate and over 250 state athletic titles, reflecting a community deeply invested in student success. The district operates approximately 70 school buildings, ranging from elementary schools to comprehensive high schools.

Scope: District-wide installation across approximately 70 school buildings, making this the largest known school security window film project in the United States.

Product: 3M Scotchshield Security Window Film S2400 with the 3M Impact Protection Attachment (IPA) system.

Installer: Epic Security & Architectural Window Films — a multi-year 3M National Dealer of the Year and one of the most experienced 3M security film installation firms in the country.

Key feature: Ballistic and impact field testing that outperformed competing products, leading to the selection of 3M S2400 with IPA.

Why 3M Scotchshield S2400 with IPA?

For a project of this unprecedented scale, the district conducted rigorous evaluation of available security film products. 3M's Scotchshield S2400 Security Window Film, combined with the 3M Impact Protection Attachment (IPA) system, emerged as the clear winner after extensive field testing.

The 3M Scotchshield S2400

The S2400 is a high-performance security film from 3M's Scotchshield line, designed for forced-entry and impact resistance. Key specifications include:

• Multi-layer construction: Multiple layers of polyester film bonded together with proprietary adhesives for maximum impact resistance
• Thickness: Designed to provide substantial forced-entry delay while remaining compatible with standard window frames
• UV protection: Blocks 99% of harmful UV radiation
• Optical clarity: High visible light transmission maintains natural daylight in classrooms
• Durability: Engineered for long-term performance in high-traffic educational environments

The 3M Impact Protection Attachment (IPA) System

The IPA system is 3M's proprietary mechanical attachment method that anchors the security film directly to the window frame. Rather than relying solely on edge-seal adhesive, IPA creates a structural connection between the film and the building frame using a specialized extrusion and adhesive system. This significantly increases hold time because an intruder must defeat not just the film but also the mechanical connection to the frame — a much harder task than simply cutting or peeling the film.

"The IPA system is what separates a good installation from a truly secure one," said a representative from Epic Security & Architectural Window Films. "The film itself is incredibly strong, but without proper attachment to the frame, the entire assembly can be pushed out as one piece. IPA solves that problem by mechanically locking the film to the framing system."

Field Testing: Performance Under Real Conditions

The district conducted its own ballistic and impact field testing before selecting the 3M system. The testing simulated real-world attack scenarios, including:

• Impact testing: Simulating thrown objects and blunt-force attacks on filmed glass
• Forced-entry testing: Simulating sustained attempts to breach the glass assembly
• Comparative testing: Head-to-head evaluation of 3M S2400 with IPA against competing products

The 3M Scotchshield S2400 with IPA consistently outperformed competitors in hold time and structural integrity under the district's test conditions. This real-world validation — as opposed to relying solely on manufacturer data sheets — gave the district confidence in its product selection.

The Installer: Epic Security & Architectural Window Films

Epic Security & Architectural Window Films has been a multi-year recipient of the 3M National Dealer of the Year award, placing them among the elite 3M-authorized installation firms nationwide. Their experience with large-scale commercial and institutional projects made them the natural choice for a project of this magnitude.

For a 70-building district-wide rollout, the logistical challenges were significant:

• Scheduling: Coordinating installation at 70 different buildings while minimizing disruption to classroom instruction
• Access: Working around school schedules, after-hours custodial operations, and community events
• Consistency: Ensuring uniform installation quality across dozens of buildings with different architectural designs, glass types, and frame conditions
• Quality control: Maintaining 3M-certified installation standards across a large crew working at multiple sites simultaneously

"Managing a project of this scale requires more than just installation expertise," said an Epic representative. "It requires logistics planning, project management, and a deep understanding of how school districts operate. Every building has its own personality, and every principal has their own schedule. Our job is to deliver a consistent, high-quality result across all of them."

Why This Project Matters for School Security Nationwide

A Model for Large Districts

Most school security case studies involve small-to-medium districts. This Colorado project proves that security film can be deployed at scale — across 70 buildings, 53,000+ students, and 8 municipalities. For large urban and suburban districts that had questioned whether film was practical at scale, this project provides the answer.

The 3M IPA Standard

The selection of the 3M IPA system — a mechanical attachment method rather than simple adhesive-only installation — reflects an industry shift toward proper anchoring as a core requirement. Many early school security film installations used dry (adhesive-only) attachment, which provides limited hold time. The IPA system, combined with S2400 film, represents the current state of the art in retrofit security glazing.

Ballistic Testing Matters

While no security film is bulletproof, the district's ballistic and impact field testing demonstrates that not all products perform equally. The district's willingness to conduct its own testing — and to select based on those results rather than marketing claims — sets a best-practice precedent for other districts evaluating products.

Colorado School Security Context

Colorado has been at the forefront of school safety funding. Following the passage of Colorado's Safe Schools legislation, the state has allocated significant resources to school security improvements, including:

• Colorado BEST (Building Excellent Schools Today) grants: Covers security improvements as part of school capital construction
• Colorado School Security Disbursement Program: Provides per-student funding for school security enhancements
• Local levies and bond measures: Many Colorado districts have passed local funding for security upgrades

While the specific district in this case may have used a combination of state and local funding, the project demonstrates that large-scale window film installations are achievable when districts commit to comprehensive security improvement plans.
