One of the best ways to ensure the classroom environment is optimized for learning is keeping distracting outside noise out. The American National Standards Institute (ANSI) S12.60-2002 standard, Acoustical Performance Criteria, Design Requirements and Guidelines for Schools
establishes guidelines for schools to build their educational facilities—classrooms, labs, lecture halls, and libraries—to protect against unwanted sound. By exceeding the ANSI standard, Krieger acoustical doors ensure an optimal learning environment.
Plus, Krieger acoustical doors have a bullet resistance rating of UL 752 up to UL Level 3 included—with higher ratings up to UL Level 10 available—for added safety during an active shooter event.
