Harlingen CISD's achievement of 100% Texas Education Agency (TEA) Designated Safe Schools across all 32 campuses demonstrates exceptional commitment to student safety. However, comprehensive security requires protecting every potential entry point, and windows remain the most vulnerable part of any school building.

Standard glass offers no resistance to impact and creates dangerous projectile hazards when shattered. Security film changes this reality by transforming ordinary windows into protective barriers that delay intrusion and prevent glass from becoming a safety threat.
