Tennessee state law requires all new and remodeled schools to install bullet-resistant film on exterior lower-level windows and doors.

A tragic school shooting at The Covenant School, which rocked the community and pushed for a change for school safety, is one of the key factors why the law is now in effect.

“If anyone has seen the video from last year and how she shot at the glass and walked into the building, right there is your answer,” said Wayne Gregory of Eversafe Security Solutions.

It’s an answer Gregory said his company has had a 100% success rate with. They have installed film in several Tennessee schools, as well as schools all across the country.

“Over the last two months, we have stopped six attempted breaches,” he said.

“We actually do an assessment of every school before we make a recommendation about what we want to do and what we think that they should do,” he said.

Gregory said they take measurements and install the film on the interior and exterior sides of the glass, which he emphasizes is critical.

“If you really want to know what I’m selling, I’m selling time. Time for you to hide, time for law enforcement to do what they do, but the most important part is it keeps the bad actor outside of the building,” Gregory said.

The goal is to prevent tragic incidents like the Covenant school shooting from ever happening again.

The technology is designed to save lives, which is why Metro schools is hoping to have the film in all their schools by January. Wilson County is also working on it, while Williamson County already has this film installed in all of their schools.
