Ballistic Glass

Ballistic and forced-entry glass can be engineered to meet specific threat levels, from intrusion resistance to advanced ballistic protection, based on the requirements of each project. While residential applications typically focus on forced-entry resistance, institutional and high-security facilities may require higher ballistic ratings. These solutions integrate seamlessly into Portella’s custom steel doors and windows, delivering high-performance security without compromising architectural design or aesthetics.
