RC3 aluminium doors and windows are a group of aluminium and glass joinery products that meet high standards of durability, aesthetics and quality, and above all the level of safety. Each element of the structure of such anti-burglary windows and doors plays an important role in adapting the product to the RC3 class requirements in accordance with the PN-EN 1627:2012 standard. Contrary to classless window and door structures and products of lower classes, RC3 doors and windows are equipped with a number of reinforcements which improve the burglary resistance at sensitive points. The proper and proportional use of such reinforcements is confirmed by static load tests, dynamic load tests and manual burglary tests. All anti-burglary components contribute to the final result of the research classifying windows and doors as burglar-resistant in the high RC3 class. An additional advantage of RC3 doors and windows is their aesthetics. RC3 window and door structures do not have external profile reinforcements, they do not differ visually from classless windows and doors, which positively affects the aesthetic appearance of the entire building without provoking burglary attempts.
are specialised products, the launch of which is preceded by a series of laboratory tests confirming the burglary resistance classification of the structure. Classification of windows and doors in terms of burglary resistance is a source of information of when and how the window or door structure is able to provide effective resistance against equipped burglars. Such information is extremely valuable and allows investors to select the optimal windows and doors for the building in terms of its risk of burglary. Achieving the RC3 resistance class for doors, and especially for windows, is a very good result confirming high resistance to impacts, balancing tests and a few minutes' attack with the use of a set of tools including screwdrivers, wedges, hammers and crowbars. The process of testing the resistance of windows and doors to burglary meets the requirements of research standards and consists of a series of sequential tests verifying the resistance to static, dynamic and manual burglary tests. The resistance of windows and doors to static loads is tested in accordance with the PN-EN 1628:2012 standard. In the closed and locked position, the sashes of windows and doors are subjected to static loads with test values at critical design points, i.e. at the locking points and in the corners. After the test load is applied, the wing deformation degree is checked by relocating the tester. The places where static loads are applied for the door are the corners of the fillings, as well as the hinges with securing pins and the bolts of the main lock. The testing of windows and doors in terms of resistance to dynamic loads is carried out in accordance with PN-EN 1629:2016-03 and PN-EN 1629:2012 standards, and it consists in hitting the tested structure with an impact object weighing 50 kilograms dropped from a height of 75 centimetres. The structure of the window or door is struck centrally three times and once in the corners, and after the impacts have been made, the deformation of the structure is also checked with a tester. The resistance of windows and doors to manual burglary tests is carried out in accordance with the PN-EN 1630:2016-03 and PN-EN 1630:2012 standards. This type of test can be divided into two stages, i.e. the initial one that determines the direction of the attack, and the main one, which is the actual test of resistance to a manual burglary attack. In the case of RC3 aluminium windows and doors, within the time specified in the standard, tests are carried out to bend the sash, detach the hinges and destroy the locking system. The deformations created during the tests are examined with appropriate testers. The series of laboratory tests that classify windows and doors at the RC3 level is quite devastating and requires the preparation of several samples for the testing process.
Contrary to the lower classes of burglary resistance, the RC3 window and door constructions are equipped with a number of additional reinforcements effectively increasing the level of security. The high class of burglary resistance is the result of the use of appropriate components such as reinforced profiles, anti-burglary fittings and glazing. The creation of window and door structures in the RC3 class requires the solution of certain technological issues and the development of details that are not present in standard aluminium window and door structures. The resistance of aluminium doors and windows results, among other things, from the excellent parameters of aluminium profiles, which are damage-resistant, light and, at the same time, extremely durable. Aluminium profile systems for window and door constructions have solutions that allow for high burglary resistance while being adapted to the requirements of the thermal insulation of the building.
requires experience, thoughtful solutions and precision in their execution. Every detail of the structure is made with special care, so that the level of protection of windows and doors exactly meets the requirements of the PN-EN 1627:2012 standard. The burglary resistance of aluminium windows and doors in the RC3 class is the result of the use and skilful connection of anti-burglary components. In addition to durable aluminium profiles, fittings and glazing of windows and doors play an important role. The hardware used in anti-burglary doors and windows is characterised by a reinforced structure and special anti-theft elements. Thanks to specialised solutions, optimised for high burglary resistance, window and door fittings are one of the key elements ensuring reliable operation and anti-burglary classification at the RC3 level.
The window hardware has a strong anti-drill protection, special catch rollers and an increased number of locking points. Despite the greater number of locking points, they do not cause much resistance and the comfort of their operation does not differ from a conventional window equipped with a basic set of fittings. The doors are equipped with locks of at least class 5 security in the PN-EN 12209:2005 standard, anti-burglary inserts, door handles on plates that protect against drilling, as well as fixed bolts protecting the hinges against being prised. Optionally, the RC3 class aluminium doors are equipped with automatically locking multi-point locks. The anti-burglary window and door structures are filled with aluminium sheet panels or glass packages. Insulated glass packages used for RC3 class aluminium structures are made of panes in a multi-layer system of tempered glass separated by a layer of PVB foil. The quality and structure of the glass pane is extremely important, because it has a great impact on the strength and resistance to burglary; therefore, in the construction of RC3 class windows and doors, it is required to use glass of a class not lower than P5A according to the PN-EN 356 standard. An important issue is also how the glass is mounted in the frames and sashes of RC3 windows and doors. For the installation of glazing in anti-burglary window and door constructions, glazing strips with a closed cross-section are used, resistant to pushing out. The contact of the edge of the glazing with the RC3 door and window profiles is filled with a special sealing compound, which is a very good connection between the glass and the structure and an effective additional anti-burglary protection.
Anti-burglary windows and doors, despite their special design and equipment, cannot fulfil their function without a permanent connection to the wall of the protected building. RC3 aluminium doors and windows are characterised by a high standard of protection against burglary, while the combination of their structure with the walls of buildings still remains a critical point. That is why it is so important to design and accurately apply the RC3 window and door assembly technology. Each anti-burglary door and window should be installed in accordance with the manufacturer's instructions, using appropriate materials and preferably by trained contractors. RC3 doors and windows are equipped with a rich set of security features that hinder burglary and extend the time needed to break through them. They provide effective resistance to attack with the use of simple tools and are a group of products recommended for single-family housing, public utility buildings and other facilities with an average level of burglary risk.
