Burglar-resistant windows

Burglar-resistant windows offer increased resistance to break-in attempts. A standard closed window also forms a barrier, but additional security features make it harder to lever the sash open or force the glazing. Protection depends on the hardware, glazing, construction and installation. The required RC class is verified for the complete window, and we select the fittings to meet the project's needs.

Application

Where are burglar-resistant windows worth using?

Security features are particularly important for windows accessible from ground level, a terrace or a balcony. We also consider garden-facing glazing and other easily accessible areas. Features can vary between different parts of the building.

We supply made-to-measure windows with your chosen colour, divisions and opening style. Security features can be combined with thermal or acoustic insulation requirements where the selected system permits this configuration.

01

Hardware and locking keeps

Locking points and suitable keeps make it harder to lever the sash open. Their positioning and interaction with the profile are part of the window’s construction.

02

Protective glazing

Laminated glass with suitable interlayers increases resistance to penetration attempts. Glazing selection takes account of the required protection, its weight and the system's capabilities.

03

Handles and fixings

Key-locking handles or other handle security features complement the fittings. Correctly fixing the frame to the building substrate in line with the construction requirements is equally important.

Before choosing

What should you compare in a quotation?

RC resistance class
If you need a specific class, we check its certification for the entire assembly. Protective glazing or selected hardware alone does not give a window an RC classification.
Complete fittings
The specification lists the glazing, hardware and handle security. This lets you compare quotations for windows with genuinely comparable features.
Installation conditions
During measuring, we assess the supporting structure and installation method. Security features must be paired with appropriate installation in the specific building.

Questions before buying

Burglar-resistant windows — what should you know?

Does a security window guarantee that a break-in will not happen?

No window offers complete protection. An assembly with a specified resistance is designed to make forced entry harder and delay an attempted break-in. We select the security level to suit your project; it can form part of a wider building protection system.

Should every window in a home have the same fittings?

That is not always necessary. We can prepare different configurations for the ground floor, upper floor and patio access, considering how accessible the windows are from outside and any requirements in the design or set by the insurer.

What should you prepare for a quotation?

Approximate dimensions, facade photos and details of the floor level and opening style. If you require a specific RC class, state it at the outset. We will use this information to select the assembly and installation scope.
