A method of using an anti-ballistic protection system for protecting an interior space in a building. The ballistic barrier includes a laminated material having a plurality of layers of lightweight, flexible, ballistic resistant material such as woven sheets which are secured together into the laminate using a adhesive, heat weld, or stitching. The ballistic barrier is configured to be in a compact retracted state which can be deployed to provide a protective state to protect against kinetic ballistic projectiles. The system may include an automated control system operably configured to change the state of the ballistic barrier from the retracted state to the protective deployed state, such that upon sensing a threatening event or condition triggers a transition from the retracted state to the deployed protective state such that in the protective state. The ballistic barrier in the deployed state is configured to be resistant to penetration by high-speed ballistic projectiles such as a bullet fired from a gun or a shrapnel from a bomb to protect the interior space.

A laminated glass includes first and second glass plates. First and second interlayers are arranged on the first and second glass plates, respectively. The first and second glass plates are arranged so as to have the first and second interlayers face each other. An enclosing layer is arranged between the first and second interlayers. The enclosing layer includes a functional member having a sidewall, and a dummy layer arranged on the sidewall, the functional member including one or more transparent layers. The functional member has a thickness of 200 μm at a maximum. The dummy layer is made of a thermoplastic resin. When denoting an average refractive index of the transparent layers included in the functional member as nA, and denoting a refractive index of the dummy layer as nB, a difference Δn of the refractive indices expressed by an absolute value |nA−nB| is 0.05 or less.
