Agressiya the broken glass or how to make glass safe
If to consider dwelling of the primitive person, meaning a rocky cave, from the point of view of maintenance of safety of its inhabitants it, perhaps, could apply on the sample of reliable protection. Has filled up from within an input with the big stone, has fixed its log and all - sleep easy. Neither the bad person, nor a furious animal will not get. As there are no ways for purpose achievement. Namely: doors are not present, windows are not present, walls, a floor, a ceiling and a roof are merged in an unapproachable stone monolith.
Weadmit to themselves: we began to get used already to elegant and graceful buildings with the glazed doors, windows and, moreover, with transparent facades and roofs. And, really, - was stable increasing dynamics of consumption of glass in modern building recently is observed. In the majority of modern structures, - among which it is a lot of shopping centres, the shops, covered market complexes, the area of the glazed designs acting in a role of transparent boundaries, take to 80 % of the area of a facade. The number of the buildings which walls are executed entirely from glass has considerably increased. And it is explainable. It is difficult to give up to itself in pleasure to behold through windows of people, beauty of the nature, architectural masterpieces. During too time it is impossible to imagine, for example, a modern supermarket without a show-window with corresponding registration. In the given aspect the glazed apertures, unconditionally, are good. But here as a barrier on a way of the burglar they are frequently useless. If, of course, not to accept special counter-measures as it is absolutely simple.
… There are problems? - There are decisions!
The most trivial method to protect fragile glass - to establish metal lattices. However, as shows the statistican of thefts, it not the most reliable. Any more not speaking about doubtfulness of its aesthetic parametres. And it is rather actual for modern shopping centres. The special tool of the salvor and in a few minutes a lattice is enough to have there is on the earth, and a malefactor - in the house.
More effective, civilised and, it is necessary to note, rather graceful method of maintenance of safety of the glazed apertures - replacement of usual glasses by compositions from glass and the protective polymeric film, supplying necessary for a concrete category of object a protection class on RD 78 Ministries of Internal Affairs of Russia "Protective osteklenie. Classification, test methods, application", and also GOST 30826-2001 "Glass multilayered building appointment". At conformity of such composition to requests of the given document on stability to ill-intentioned actions it can serve as alternative to application of metal lattices.
Glass with a protective film is capable to delay the discouraged thief for long time, granting protection services possibility to react to a security alert and to prevent a crime. Equipped even the most thin film, glass becomes bezoskolochnyim and detains the strongest blows, not scattering on pieces, preventing possible cuts, wounds (and at times and more tragic outcome), damage of the goods by splinters in case of show-window damage, saving up the expensive equipment and furniture.
Do not think of splinters haughtily! At explosion enough the big capacity in the street compositions from usual glass and special explosion-proof polymeric films in a condition to be kept in a frame and to save in inviolability everything, that was in a premise. At even more powerful explosion (to several tens in kg. Trotyl) such compositions usually at first bursting, cave in inside under blast wave effects, and behind that at pressure depression, remain in a frame or fall on the earth integral sheet.
According to the decree of the mayor of of Moscow # 1384-RM from 28.12. 2000 "About urgent measures on realisation of the program safe ostekleniya" explosion-proof films trading, cultural, sports and business complexes with mass stay of the population, and also the residential buildings possessed in populous streets and the areas should be protected.
What class of protection is necessary to you?
Application of protective glasses on protected objects is based on very simple rule - the more important object, above its category or as still speak, the importance (material, historical, cultural, etc.), the is stronger owe glass - thicker a protective film, more than its layers.
Protective osteklenie in most cases use in a combination to means of the security alarm system (shockproof compositions - with izveschatelyami razbitiya glasses, bulletproof glass - with buttons of the disturbing alarm system). At a choice of a class protective ostekleniya for concrete object, except its special importance, it is necessary to consider still real time of reaction of a protection service for the security alerts acting from means. The increase in this time (for example, because of possible technical or transport problems) requires a choice of stronger ostekleniya.
