Anti-burglary fittings – how to genuinely deter a break-in
Most window break-ins take less than 60 seconds. A window with security fittings requires time and noise – two factors burglars avoid. Effective protection doesn't mean replacing the whole window.
How to genuinely secure a window against break-in?
Glass alone won't stop a burglar – it can be broken in seconds. The key is securing the frame and hardware. If overcoming the window takes more than 60–90 seconds and creates noise – in 80% of cases the burglar will give up.
Effective protection = reinforced peripheral hardware + anti-burglary bolts + key-locking handle. It's a system, not a single element.
Elements of an anti-burglary security system
Anti-burglary bolts – metal bolts built into the peripheral hardware. When closed they enter sockets in the frame. They prevent the sash being forced even after the glass is broken.
Handle with cylinder lock – prevents the handle being operated without a key. Effective when a burglar tries to reach through a hole after breaking the glass.
Window restrictors (stops) – limit the opening angle. The window can be tilted but not opened wide enough to climb through.
Profile reinforcing plates – steel inserts at the point where the sash meets the frame. They reinforce the critical point that is levered first.
Which windows to secure first?
Ground floor and first floor near a tree or balustrade. Courtyard-facing windows – not visible from the street. Cellar and garage windows – often overlooked by owners, noticed by burglars.
How much do anti-burglary fittings cost?
Window restrictor: from 45 PLN. Locking handle: from 85 PLN. Bolts for existing hardware: from 80 PLN per window. Complete single-window security (hardware + handle): from 220 PLN. Free diagnosis.
What security upgrades do we install?
Each element works independently – can be installed individually or as a complete set
Hardware locks
Mechanical locks fitted to existing perimeter hardware prevent the latch from being slid back after the glass is punched out or cut. This is one of the most effective window security upgrades without full replacement.
Opening restrictors
A restrictor allows the sash to tilt open a few centimetres – enough for ventilation, but prevents full opening without a key. Especially recommended for bedrooms and children's rooms.
Reinforced multi-point hardware
Replacement of standard hardware with an RC2-class multi-point locking system (formerly WK2). The bolt secures the sash at a minimum of four points – forcing it open requires significantly more time and effort than a standard window.
Window opening sensors
Magnetic or reed-contact sensors attached to the frame and sash. When the window is unlatched they send a signal to the alarm panel or a notification to your phone. Installation requires no drilling into the window profile.
Floor bolts for balcony doors
An additional bolt that locks balcony doors from the bottom – used as a supplement to the standard lock. Particularly effective on double-leaf and active/passive door sets.
Servicing of existing anti-burglar hardware
Adjustment, lubrication, and condition check of existing locks, restrictors, and hardware. Anti-burglar fittings often need realignment after a few seasons to ensure they latch correctly.
What actually protects a window against break-ins?
Three things worth knowing before installation
Opening restrictor – simple and effective
An opening restrictor is often the simplest and most affordable step with a real impact. A window fitted with a restrictor can still be ventilated, but cannot be opened wide without a key — a burglar won't get through a gap of a few centimetres. Installation takes 20–30 minutes, with no hardware replacement required.
RC2 class – what does this certification mean?
The PN-EN 1627 standard defines window burglar-resistance classes (RC1–RC6). RC2 means that a window fitted with such hardware withstands an attack using hand tools (crowbar, screwdriver) for at least 3 minutes. Most standard PVC windows are RC1 or below. Upgrading the hardware to RC2 does not require replacing the entire frame.
Layers of protection – each one buys more time
No single element provides one hundred percent protection. An effective system combines anti-burglary hardware + a lockable handle + an opening sensor + optionally an external roller shutter. Every layer extends the time needed to break in — and statistics show that most intruders give up after 2–3 minutes of resistance.
