anti-burglary facades
Aluminum anti-burglary facades meet special requirements pertaining to anti-burglary protection of buildings. Anti-burglary facade structures are based on standard curtain wall solutions in post-transom systems additionally equipped with elements raising their resistance against attempts to penetrate them from the outside. The production and assembly of light curtain walls in post-transom technology makes it possible to implement anti-burglary protection through the application of several indispensable elements such as anti-burglary glass, special fastening of clamping strips and assembly elements specially intended for applications of this type. Such technology for implementing enhanced resistance to burglary for curtain walls does not require changes in the exterior appearance of anti-burglary facades in comparison to standard constructions. Anti-burglary facades do not differ visually from traditional facades because of this, and through their aesthetically pleasing appearance, add functionality, elegance and prestige to any building.
Aluminum anti-burglary facades
are built based on post-and-transom systems with the appropriate profile width, translating to greater strength of the structure and the possibility of making large partitions of facades. Basing on typical aluminum post-and-transom system, anti-burglary structures of curtain walls are also characterized by high technical specifications with regard to thermal and acoustic insulation, watertightness and air permeability. Thanks to the high load-bearing capacity of profiles applied in the construction of light curtain walls, they are perfectly suited for special applications, including those with enhanced burglary resistance. The statics of such structures allow for fastening heavy glass panes in them, which simultaneously require the appropriate installation depth in profiles.
RC2 anti-burglary facades
are specialized aluminum curtain walls ensuring a basic level of protection against burglary for a building. RC2 aluminum facades are structurally a modification of the commonly applied post-and-transom system. Posts, transoms and clamping strips serve as the basis of anti-burglary solutions in class RC2, alongside masking strips on posts and transoms applied in traditional aluminum facades. Due to the nature of the structure of facades and their role in buildings, burglary resistance is tested only from the exterior, however resistance tests are conducted according to all current testing standards. Burglary resistance tests of facades cover checking of anti-burglary parameters with regard to resistance to static loads according to PN-EN 1628:2011, to dynamic loads according to PN-EN 1629:2011 and to manual burglary attempts according to standard PN-EN 1630:2011. For the test result to be positive in all three of these scopes, it is important to apply appropriately strong profiles, glazings and to properly space the screws fastening the clamping strip.
RC3 anti-burglary facades
are a professional way to secure buildings against burglary and theft. Aluminum curtain walls of this type ensure a high level of protection against burglary for buildings. They are also made based on tried and tested post-and-transom systems, however, in contrast to facades of lower classes, they are equipped with stronger glazing and have stronger fastening of the clamping strip. RC3 facades provide excellent protection against attempts at forced entry into buildings, and their application does not deprive the facade of its typical appearance. In terms of exterior appearance, RC3 facades do not deviate from ordinary aluminum curtain walls, and from the interior, it is possible to make the surfaces of post and transom profiles flush.
Design of aluminum anti-burglary facades.
The aluminum sections and fastenings functioning in anti-burglary facades do not deviate fundamentally from those applied in traditional curtain walls without anti-burglary resistance. Anti-burglary facades are built using vertical profiles – posts, and horizontal profiles, i.e. transoms. An important component of an anti-burglary facade is a clamping strip with an increased number of fastening points, but the absolutely critical component is filling with the appropriate protection class. For facades in class RC2, the appropriate laboratory-tested filling is a glass unit in class P4A according to PN-EN 356:2000, whereas for facades in class RC3, the filling is class P5A glass. Insulators of posts and transoms and interior gaskets of post and transoms supplement the facade's structure. The fastening elements are aluminum bases fixing elements to the floor as well as steel intermediate fastenings. Post-transom structural joints are based on aluminum connectors and steel pins, and their load-bearing capacity is an important feature when applying large and heavy anti-burglary glazings. The post-transom structure of anti-burglary curtain walls ensures broad capabilities of fastening various opening elements into facades, e.g. windows and doors with burglary resistance levels corresponding to facade classes according to standard PN-EN 1627:2012.
Application of aluminum anti-burglary facades.
Aluminum curtain walls in class RC2 are intended to stop random burglars equipped with basic tools like screwdrivers, pincers, wedges and small hand saws. RC3 class facades are applied in buildings at moderate risk of burglary and are designed to nullify attempts to break through protections by burglars with some experience and a better set of tools, including crowbars, hammers and drills. Aluminum anti-burglary facades are applied in buildings being potential targets for burglars; they are installed in military and police facilities as well as in banks, post offices and diplomatic facilities, as well as in other buildings requiring special anti-burglary protection.
