Case Study: Princeton ISD (Texas) - Security Window Film Installation

Princeton ISD used school safety grants and a fast, grant-friendly installation plan to harden glass at its campus facilities in Princeton, Texas. Epic Solar Control's portfolio shows security film on the district's elementary, middle, and high school buildings, making this a strong example of how a growing suburban district can cover multiple campuses without a long construction timeline. The takeaway is simple: when districts want more delay at the glass, security window film is one of the fastest upgrades available.

Project Overview: Princeton ISD, Texas

District context: Princeton ISD is a rural public school district in Princeton, Texas, serving more than 5,400 students across nine schools. Fast growth in Collin County means more students, more buildings, and more glass to protect.

Scope: School safety window film installed on interior and exterior doors and windows at district facilities.

Schools mentioned: Harper Elementary, Godwin Elementary, Lacy Elementary, Lowe Elementary, Smith Elementary, Southard Middle School, Clark Middle School, and Princeton High School.

Funding: School safety grants helped cover the project.

Timeline: The portfolio page does not publish a formal completion date, but the retrofit was completed as part of a grant-backed district safety rollout.

Cost: Not publicly disclosed.

Why it mattered: Princeton needed a security upgrade that could scale across multiple schools without a disruptive replacement project.

What the Portfolio Shows

The Epic Solar Control project page makes the district's priorities clear. The film was chosen to enhance security, improve glare reduction, and help with shatter resistance while preserving the normal use of each school building.

The most useful line in the project summary is that the film can "help buy precious time by slowing down intruders." That is the operational benefit districts actually care about. The point is not to make the glass indestructible. The point is to convert a zero-second breach into a delayed breach that gives staff time to react.

Why Princeton Is a Strong Case Study

• The district covered a wide set of buildings, not just one office or one entrance.
• The project uses grant funding, which makes it easier for other districts to copy.
• Film can be deployed in phases, so a district like Princeton can protect its most exposed schools first.
• Because the schools are part of a growing suburb, this is the kind of project that tends to expand over time.

Lessons for Other Districts

Princeton ISD shows that school security film is not only for big-city districts or high-profile campuses. Suburban and rural districts can use the same playbook: identify the glass most likely to be attacked, fund the work through safety grants, and install the film with minimal interruption.

It also helps that Epic highlighted both security and energy-related benefits. That makes the upgrade easier to justify to boards that need more than one reason to say yes.

Key Takeaways

• Princeton ISD used school safety grants to install window film at multiple facilities.
• The district's portfolio includes eight named schools, from elementary through high school.
• The project focused on both interior and exterior doors and windows.
• The film's main value is forced-entry delay, not bullet resistance.

Find Installers Near You

Suburban districts like Princeton usually need a turnkey installer that can work across several campuses with a single specification.

Conclusion

Security window film is not bulletproof, but it can still be a smart, grant-friendly delay layer for districts that need to move now. Princeton ISD's project is a good reminder that the best school security upgrades are often the ones that can be funded, installed, and defended clearly.
