Burglars most often enter single-family homes through easily accessible window openings and patio doors. Therefore, when planning construction or renovation, it is worth investing in solutions that effectively deter intruders. Real security windows are not a matter of marketing, but of precisely defined standards and technical parameters. What should you look out for to create a truly secure home?
RC Resistance Class – What Do These Abbreviations Mean?
The resistance of windows and doors to forced opening attempts is defined by the European RC (Resistance Class) standard. For residential housing, two classes are of key importance:
-
RC1 Class: Provides basic protection against burglary attempts using physical force (e.g., kicking, shoulder-striking).
-
RC2 Resistance Class: This is the recommended standard for single-family homes. A window in this class resists an intruder equipped with simple tools like a screwdriver, pliers, or wedges for at least 3 minutes.
Anatomy of a Security Window: Hardware, Glazing, and Handles
For a window structure to obtain an anti-burglary certificate, it must consist of several harmonized elements. First, special security hardware is essential, equipped with mushroom locking cams and anti-pry strikers mounted directly into the steel reinforcement inside the frame. Second, standard glass must be replaced with safety glass (laminated with PVB foils, e.g., P4A class), which cracks upon impact but does not shatter, preventing entry. The entire setup is completed by a lockable handle with a key and an anti-drill plate.
Remember that even the highest quality components will not fulfill their purpose without professional installation. At AM Okna, we ensure that windows with increased burglary resistance are installed strictly according to the manufacturer's guidelines, guaranteeing full protection of your property.

FAQ: Do external roller shutters replace security windows? Standard aluminum shutters provide a visual and psychological barrier, but they do not pose a mechanical obstacle for a thief. Only combining RC2 class windows with certified security shutters provides the maximum level of safety.
