Windows: main entry.
Over 80% of all burglaries in single-family houses are attributable to inadequately secured windows.
Burglary protection for Finstral windows.
Standard at Finstral: very high security.
Knowing the weak points will help you protect yourself.
We adopt the burglar’s mindset.
Whether or not life is made easy for burglars depends on how well a window is secured. More than two-thirds of all burglaries can be prevented by means of modern security.
High security as standard.
Even our base models meet the highest standards. Thanks to everything from the robust frame construction to the high-grade security hardware with roller mushroom head bolts and sash frames that are always securely bonded.
Security hardware.
Roller mushroom head bolts as standard at Finstral.
Standard market windows can be prised open in ten seconds. Our hardened-steel roller mushroom head bolts make it virtually impossible to force the window open, as the mushroom head on the sash hooks tightly into the recess of the solid locking part on the frame.
Glass-frame unit.
Solidly bonded around the full window perimeter.
A glass pane is traditionally clamped into the sash frame. Which permits a certain amount of movement in the frame. At Finstral, the panes are always bonded in the frame around the full perimeter such that glass and frame form a single, solidly connected, rigid unit that is much harder to prise open.
Middle gasket.
Always safely concealed hardware components.
Window frames with a middle gasket make it harder for burglary tools to reach the hardware from the outside. As Finstral windows are always fitted with a middle gasket, they offer greater burglar resistance than windows with conventional frames.
Locking points.
At least four security locking points for added protection.
With the FIN-Window system, windows and doors are always fitted as standard with solid security locking points and roller mushroom head bolts at four positions. On request, we can supply RC 2- or even RC 3-certified security fittings.
Always burglar-resistant windows.
Extra security for well-being at home.
Finstral sets itself apart from other manufacturers by offering reliable security even with its standard window versions. To achieve maximum burglar resistance, our windows can be fitted with additional security features.
| Normal market security standard | Finstral security standard | Finstral standard for RC 2 requirements |
|---|---|---|
| Mushroom head striking plate | Roller mushroom head security striking plate The mushroom head on the sash tightly interlocks with the openings in the solid striking plate on the frame to further secure the window. | Roller mushroom head security striking plate and corner hinge The mushroom head on the sash tightly interlocks with the openings in the striking plate on the frame while an additional securing point at the corner hinge further enhances window security. |
| One or two locking points | Four locking points Finstral windows are fitted as standard with solid security locking points and roller mushroom head bolts at four positions. | One locking point every 85 cm around perimeter Full-perimeter security locking and solid screw connections for the striking plates vouch for enhanced security. |
| Often only weatherstripping | Always with middle gasket A middle gasket – instead of simple weatherstripping – makes it harder for burglary tools to reach the hardware components from the outside. | Always with middle gasket A middle gasket – instead of simple weatherstripping – makes it harder for burglary tools to reach the hardware components from the outside. |

Extra-high protection for your windows.
Always the biggest choice of security options.
For maximum burglar resistance, you can fit your windows and lift-and-slide doors with additional security features.
Perimeter security hardware.
Powerful safeguards.
Full-perimeter security locking and – if required – additional securing at the corner hinge vouch for even greater burglary protection.
Drill protection.
Hard to drill into.
The hardened-steel drill protection located directly in front of the gear mechanism prevents the sash from being drilled into from the outside.
Security handles.
Locked.
Lockable or push-down window handles block the entire locking mechanism, thereby preventing the bolt from being pushed out of the striking plate.
Safety glass.
Splinters without breaking.
Multiprotect laminated safety glass comprises two glass panes bonded together with a highly tear-resistant film.
Window sensor.
Detects every movement.
Concealed magnetic sensors tell the alarm system whether the windows are open, tilted or closed.
Securely fixed glass.
Firmly anchored pane.
Sash-reinforcing PVC blocks prevent the window panes from being prised out.
Anti-lift device.
Impossible to prise open.
The solid anti-lift device prevents the sash from being lifted up when any attempt is made to lever it open.
Security packages.
To meet RC 2 or RC 3 requirements.
On request, we can supply RC 2- and RC 3-certified security fittings.
Interview with Dipl.-Ing. Robert Krippahl
“We go about it like burglars.”
Burglar resistance depends above all on window security. Robert Krippahl from the Institut für Fenstertechnik (ift) Rosenheim explains what construction clients should look out for when choosing their windows.

A secure window is more than just a detail – it is the product of an intelligent overall concept. Finstral develops windows in which all components interact perfectly: from sturdy profiles and robust glass to precision hardware systems. This paves the way for solutions that reliably withstand break-in attempts while promoting lasting comfort and well-being in the home environment.
FAQ
What resistance class is appropriate for my windows?
Resistance class RC 2 is recommended for normal residential buildings. Enhanced class RC 3 security is advisable for properties containing valuable assets as well as for vulnerable office and administrative buildings. Moreover, the less visible a window is from the outside, the greater the distance to the next-door neighbour and the more valuable a property appears on the exterior, the higher the level of burglary protection should be. Finstral windows set the highest benchmarks in the market. They are always fitted with roller mushroom head bolts, at least four locking points, a middle gasket and bonded panes. RC 2- and RC 3-certified security fittings are available on request. For further details, please visit: Burglary - Finstral Planner.
Can I retrofit my windows with burglary protection solutions?
The scope for retrofitting existing windows with burglar-resistant capabilities is limited. Given that security features are inherently designed into Finstral windows, we recommend replacing the entire unit to achieve fully effective burglary protection.
How does safety glass work?
Finstral offers two kinds of safety glass. Bodysafe toughened safety glass (TSG) guards against injury: should the glass break, then it will shatter into small, blunt pieces instead of sharp shards. Multiprotect laminated safety glass (LSG), comprising two glass panes bonded together by a tear-resistant film, offers both injury and burglary protection. If the glass fractures, the safety interlayer holds the shards in place, making the window difficult to penetrate. For further details, please visit: Safety glazing ‑ Finstral Planner.
