Windows which protect against burglary

How do you protect your home against burglars? It is best to provide all-round protection of your home against theft and vandalism. As it happens, replacing window joinery can influence the security of your property. It is worth knowing how windows should be equipped to provide more effective protection for houses and flats.

Burglar-resistant fittings

A burglar’s route to stealing property frequently leads through windows or patio doors. Forcing these open or smashing panes are the most common methods of opening up the closed living area. “An anti-burglary window is one which has fittings with increased anti-burglary properties, with a glazing unit in a burglar-proof structure, e.g. pane P3 or P4 type, and installed appropriately in the opening in the building. Burglar-proof windows are categorised according to their resistance to break-ins, based on classes RC1-RC6. In PVC windows, the most popular anti-burglary class is RC2, with the highest anti-burglary class being RC3 (the remaining classes apply to aluminium and steel products). Forcing these open is a great challenge for burglars, requiring the use of non-standard tools, thus significantly delaying the opening of the sash and entry into the building. Windows of class RC1 have a minimum of four anti-forcing points, but at RC2 level they are reinforced with at least eight points, which protect the window even more effectively against any attempt to use force, such as shoving with the shoulder, using sharp tools, etc.,” explains Anna Latus of Budvar Centrum. It is worth knowing that standard windows have one such safeguard. This point is located in the sash of the window along the perimeter and its task is to work with the ZnAl (an alloy of zinc and aluminium) clips connecting the sash with its frame. This is the so-called safe point, and the more of these a window is fitted with, the more effectively it protects against burglary.

Anti-burglary panes and safe assembly

Fittings are not everything. In the case of a window with high burglary resistance, it must absolutely be equipped with steel sections to which are screwed anti-burglary clips, forming a barrier against break-ins, and with an anti-burglary glazing unit. The anti-burglary panes used are usually in classes P3 and P4, e.g. pane 44.4 – this is a pane made from two 4 mm thick sheets of glass stuck together, and four sheets of foil, each one 0.4 mm thick, giving the pane a total thickness of around 9.6 mm. It is very important that windows which are to provide protection against burglars are properly installed. The method usually applied, using foam and a few anchor bolts, allows burglars to even tear the entire window structure from the wall, so it is worth getting recommended professionals to deal with the installation. They will use the right materials for a more burglar-proof window assembly.

Reed switches – an alarm sensor in the window

The alarm systems in general use work with alarm sensors fitted to the windows. These are reed switches - magnetic proximity sensor switches connected to an alarm system, which enable an audio signal to be activated outside the building if the window is tilted or opened. The device may be installed outside the window fittings (simplified reed switch), and it then works in the event that the window is tilted or opened. This is a great support against break-ins, as well as providing a safety check during sudden changes of atmospheric conditions, as the reed switch is constantly monitoring the position of windows and doors. A reed switch mounted inside the window fittings will react much earlier, as soon as any attempt is made to shift the fittings, thus giving warning of any mechanical movement of the window, or of light pressure on the handle itself even before the window is opened.

How to handle burglars

The humble handle actually has a very great influence on household security. There are several types of handle which affect the level of anti-burglar security. A model with a key means the window can only be opened with an individual key, which prevents attempts to break in by drilling through or forcing open the sash. This type of handle is also highly appreciated by parents who want to ensure their children’s safety by preventing the risk of them opening windows when there are no adults around. Another type of handle, with a button, prevents the window from opening completely accidentally, which always provides burglars with an opportunity to enter a home freely. This is a safeguard which ensures that the fittings can only be moved by pressing the button in the open or closed window position and turning the handle. The Secustic model is a handle which gives its surroundings a warning sound if an attempt is made to breach the private space. Turning it causes a specific click-click sound, which announces that someone is trying to get in, and that this is someone who does not want to use the door and so may have dishonest intentions. The Secustic handle has a built-in safeguard which means that the fittings can only be set in movement by turning the handle itself from inside the room, and not by drilling through or mechanically shifting the fittings from the outside. Windows are particularly vulnerable to attempts by burglars to enter private spaces from the outside. Those opportunists who take advantage of ineffective window protection or the carelessness of householders (e.g. a window accidentally left open when the is no one home) are therefore particularly keen on this method. Budvar Centrum offers windows which strengthen the protection of private property and help maintain the comfort of people using a house or flat.
