Detention facility glazing is defined as translucent or transparent material constructed to withstand measurable, complex loads from intentional, sustained threats or attacks in a detention and correctional environment. Detention glazing must comply with testing standards as set forth by several administrative bodies depending on whether the facility is a local, state or federal facility. Security glazing proposed to be used in adult and juvenile detention facilities must be of the appropriate rating in relationship to the security level of the facility.
