A safety portal system for use in existing building, such as schools. The safety portal system includes a first portal section. The first portal section includes a first wall and a second wall, a first open end, a floor portion and a ceiling portion, the at least one open end defined by an outer edge. In addition to the first portal section, the safety portal system includes a second portal section. The second portal section includes a first wall and a second wall, at least one open end, a floor portion and a ceiling portion. The at least one open end of the second portal section is defined by an inner edge that cooperates and engages with the outer edge of the first portal section to create a protective overlap section. A method of installing the safety portal system includes positioning the safety portal system in a desired building and assembling the safety portal system. The safety portal system can then be secured in its desired location within the building.

An anti-ligature device for attachment to an edge of a door leaf, the anti-ligature device having a proximity sensor arranged to detect a ligature secured around the anti-ligature device. The proximity sensor may be arranged to detect a weight being suspended from a ligature secured around the anti-ligature device. The sensitivity of the proximity sensor may be user-controllable, such that the anti-ligature device can be calibrated once affixed to the door leaf.

An impact-resistant window may include features that reduce the forces exerted on the edges of related panes, thereby preventing breakage due to impacts. In a described embodiment, the in pact-resistant window comprises at least one pane made of a transparent material and a frame including a first frame portion, a second frame portion, and a third frame portion. In this embodiment, the connection between the first frame portion and the third frame portion may be configured to allow movement between the first frame portion and the third frame portion.

Safety window films are described. In particular, safety window films including a substrate including polyurethane—the substrate having a first and second major surface, an optically clear pressure sensitive adhesive, and a polymeric liner are described. The first major surface of the substrate is the top surface of the safety film, and the polyurethane has a Shore hardness of less than 80 D. Such films may provide improved physical and optical performance over conventional safety window films, while being easier to install.

A bullet-resistant door includes a wooden frame forming a perimeter structure and protective layers that are collectively secured within the wooden frame. Such protective layers include: bullet-resistant panels that are made of a base material having embedded fibrous material and that are at least semi-rigid; and bullet-resistant sheets of a woven high-strength pliable fabric. In addition, a substantially hollow core that is at least ½ inch thick is provided between the protective layers

The present invention is directed to an apparatus and system involving the use of a panel for protecting fenestrations in buildings such as windows and doors, from damage caused by storms, tornadoes, hurricanes, riots, and the like. Embodiments of the present invention include a substrate panel attached to a security film providing increased protection against wind-driven missiles associated with high winds with decreased weight and mitigating improper installation.

An anti-graffiti window film covering system that includes multiple polymeric film layers. Each layer includes a unique visual indicia to identify the number of sheets remaining in the system.

Lightweight, glidable shielded components (e.g. doors) may be used in conjunction with accredited enclosures to provide electromagnetic, acoustic and CBR protection.
