Security experts, property managers, architects and engineers are now doing something about it. Emergency preparedness has become a high priority.
Before Oklahoma City and 9/11, security window film was considered a practical way to protect building occupants against injury from flying shards of glass. The simple idea was to install the film on the inside of the windows, forming an invisible shield to capture blast-shattered glass and minimize its shrapnel effect.
This early method of applying window film was an important first step toward reducing injuries. However, the grim reality of terrorism has forced experts to understand blast phenomena and how buildings and their windows react under the stress of explosive forces.
Different anchoring and restraint systems may be used according to the types of windows and the client's budget. Structural engineers play a critical role in this process, based on their knowledge of the available technology and the behavior of building structures under load. Their analysis is the first step in determining the best system for the building. Gulling Attachment SystemThis system uses a flexible plastic strap to attach all four perimeter edges of the filmed glass to the frame, allowing significant deflection of the filmed glass while retaining the shattered pane in its frame. Using double-sided adhesive tape instead of screws, this system is suited where the window frames must remain in their original condition. Wet Glaze Attachment This system is built around carefully crafting a triangular joint of structural silicone - up to 0.5 inch at the perimeter edges of the window - connecting the filmed glass to the supporting framing. Dry Glaze AttachmentThis system employs an extruded rubber batten, creating a “factory-made” triangular joint around all four perimeter sides of a window, attaching the filmed glass to the frame. Arpal RestraintThis structural cable restraint system is suited to high-load conditions for oversized windows, or to large explosions. It is used with 12- to 15-millimeter high-strength window film. Emergency preparedness compels us to take a closer look at the windows that surround us. Considered a liability in many locations, windows that are properly secured can once again become an attractive and valuable feature in our buildings. And now, filmed glass is not only used to fight terrorism, it is also used in residential building.
The favorite of simple decorative style, translucent and hazy, the infinite expansion of space totally and segregation block of the reality, it has replaced the traditional style of residential building; we can have a good indoor natural light and also reduce visibility. It has rich color, flexible transform style, simple and real innovative, low-cost, security, environmental protection, which has become home, offices, restaurants, shopping malls prospects, and the bedroom, bathroom and other personal private space the best choice. The building advantages:1) Effectively prevent glass breakage, the protection of life and property safety. 2) Layer is separated from the vacuum ultraviolet sandwich, containing trace elements of plutonium, can absorb harmful spectrum, tune-spectrum video. 3) Prevent sound waves enter and the effective noise reaches above 38 percent, to prevent indoor noise pollution effectively and effective protection of study, sleep. 4) Reduce glare and offer added comfort. 5) energy-saving insulation can be separated more than 99 percent of the radiation. 6) Fully enjoy the sun and protect home from the stunning and the harassment of ultraviolet light at the same time. 7) Avoiding fading of furniture and reducing high expenses of air-condition. Some other feature: a) Energy conservation and environmental protection reduce the high electricity tariffs of air-conditioning and central heating. b) Avoid UV entering and indoor items bleaching and aging. c) Filter glare and reduce glare, protect the skin and vision. d) Increase the strength of the glass, reduce personal injury and the protection of property and build a stealth protection network. e) One-way perspective, the protection of privacy, making living space ease, comfort, quiet and comfort. Improve the appearance of the construction and landscaping indoor living environment. f) Noise isolation, effective guarantee of sleep. g) Economical and practical, not fading and long time using.
