What is so special about heroal security windows?
What makes heroal windows so safe
A number of different requirements need to be fulfilled for a window to qualify for a specific burglary resistance class. Security windows by heroal meet the these requirements by their number of locking points, lockable window handles, penetration-resistant safety glass, fittings with mushroom locking bolts as well as a pry-proof protection. In addition, the material aluminium plays an important role for the stability of the security window. Finally, the professional installation also makes a significant contribution to the burglary prevention a window offers.

Locking points - The more locking points, the more the burglary protection your windows provide. Four RC locking points put the windows in burglar resistance class RC 2, and twelve locking points put them in resistance class RC 3.
Anti-lift protection - Burglars often break into your house by lifting a closed or locked window. Anti-lift protection makes this considerably more difficult.
Lockable window handle - A lockable window handle is mandatory for resistance class RC 3. If the window glass is destroyed, this provides additional burglary protection.
Safety glass - Laminated safety glass makes the window less susceptible to breaking. Depending on security requirements, our specialist partners use this glass as additional protection for your heroal security windows.
Mushroom-head lock - If a house has new windows but no mushroom-head locks, burglars can break in just as quickly as they could into a house with old windows. The fittings have mushroom-shaped pins that offer optimum protection against levering.
Aluminium - All heroal windows are made of an aluminium-KS composite. Aluminium offers a very long service life and is particularly stable. This makes heroal windows ideal security windows.
What do resistance classes (RC/WK) for windows acc. to DIN EN 1627 mean?
The classification of security windows has been defined in the German industry norm DIN EN 1627. This norm uses different resistance classes in order to define for how long a window is able to resist attacks to break it open. After a revision of this norm in 2011, the original German term (WK = “Widerstandsklasse”) was replaced by the international term “Resistance Class” (RC), which has been used Europe-wide since then. The higher the resistance class, the higher the burglary prevention a window provides. The police recommend the installation of security windows which meet at least the requirements of resistance class RC 2. A number of factors contribute to the achievement of a specific resistance class. All of these factors need to meet specific requirements, starting with wall attachment through glazing and locking points to professional installation. Please find below a survey of the different resistance classes and the requirements windows of each class have to fulfil.
