A panel assembly (12) comprising two outer panels (16,20) positioned in a face-to-face relationship and made of a light-transmitting material (e.g., glass), and an inner panel (18) positioned between the two-outer panels (16,20) and made of a light-transmitting material having a greater impact resistance than the two outer panels (e.g., window glasslaminated with polycarbonate resin or a single layer of polycarbonate material). The twoouter panels (16, 20) can each have a film (30) of plastic material (e.g., a polyester film) applied to at least one of their surfaces thereby making the panels (16,20) have enhanced thermal performance, increased impact strength, improved shatter resistance, and better sun protection. Additionally or alternatively, the chambers (22,24) between the panels(16,18,20) can contain Aragon gas thereby providing increased thermal and acoustical values. The panel assembly (12) may be mounted in a frame (14) to form a security window (10).
