Certified security and burglary protection for windows

Burglary-resistant aluminium windows provide security and protection from burglary to your house, flat or commercial building. heroal safety windows offer a standard, basic protection which, thanks to the modular design of our products, may be further increased on demand. As certified by an independent test of ift Rosenheim, Institute for research, testing and certification, heroal safety windows in combination with lockable handles are resistance class RC 3-rated and thus able to resist loads of 600 kg. The protection from burglary is not visible from the outside.

What makes heroal windows so safe

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.

Double fused

The combination of a heroal security window and a heroal stainless steel security shutter gives your home an especially high degree of safety. Both security windows and stainless steel shutters on their own meet resistance class RC 3. In order to achieve resistance class RC 3, a closed and locked window must withstand a perpetrator for at least 5 minutes with a screwdriver, a crowbar and a simple drilling tool. When the two are combined, the resistance class goes up to RC 4.

Certified burglar protection

The safety and quality of heroal security windows are certified by the Institute for Window Technology (Institut für Fenstertechnik, ift-Rosenheim). ift Rosenheim determines the resistance class according to DIN EN 1627 by simulating different types and behaviours of burglars within set periods of time. For resistance class RC 4, the perpetrator must not succeed in penetrating a closed and locked window within 10 minutes using sawing tools, a cordless drill and impact tools such as an axe, chisel and hammer.
