A bullet resistant glass screen (1) is described comprising a number of glass sheets (2-5). The sheets (2-5) are separated by an air gap (6-8) and each sheet has on at least one surface a security film (10) preferably made of polyester. Each sheet (2-5) may have the film (10) on both the front and the rear surface. Increasing the air gap increases the resistance of the structure to penetration by a projectile. Standard thicknesses of window glass can be used. The polyester film can be adhered to the glass sheets by a pressure sensitive adhesive.
