In today’s volatile landscape where school shootings are unceasingly making headlines, many school officials are looking for ways to increase safety and security on their own campuses. The Houston Independent School District is no exception. As the largest school district in Texas and the seventh largest in the United States, it serves about 209,000 students across 280 campuses.

When Houston ISD Police Sergeant Karl Brown learned about 3M™ Safety & Security Window Film, he knew he wanted to see the product first-hand. NGS Films & Graphics, with offices in Dallas TX, Washington DC, and Atlanta, offered to conduct a live demonstration with Brown and his fellow officers. What resulted was a three-minute video that showcased the ultimate power of safety and security film.

The results? 3M™ Safety & Security Film, when installed with NGS Film & Graphic’s proprietary TRI-SHEILD method, took officers armed with assault rifles more than six minutes to puncture through the glass. Under an active shooter scenario, this would have meant more time for emergency officials to arrive and for students and faculty to find shelter.

“There is no doubt that it could save lives,” said James Beale, managing partner of NGS Films & Graphics. “A single minute could make all the difference in the world. This took six minutes.”

3M™ Safety & Security Window Film’s Ultra Series incorporates proprietary micro-layered and tear resistant technology. To ensure its reliability, 3M rigorously tests its window film products against a multitude of explosion and blast standards. Governments across the world have installed 3M™ Safety & Security Window Film to protect both people and property from violence.

As 3M’s largest window film dealer, NGS Films & Graphics works with school districts throughout the nation to assist them with installing film as a security measure. The company creates individual safety and security assessments of school campuses and also assist with grant applications.

“When we shared the video on social media, a commenter wrote, ‘Every school in America – not just Houston – should have that (3M™ Safety & Security Film) on the glass,’” Beale said. “I tend to agree with them.”
