Security doors

Certified burglary protection for your security

Feeling safe in your home has a significant influence on your quality of life. For higher security requirements and valuable household items, the police recommends resistance class RC 3 front doors for effective burglary protection. heroal security front doors offer you optimal burglary resistance thanks to the seamless integration of every element – from the door handle to the door construction and the installation. Depending on the equipment and construction, our security doors can also serve for escape and rescue routes in accordance with DIN 179/1125 (with CE marking) and can be made fully barrier-free up to resistance class RC 3.

What makes heroal security doors stand out

Several components come together to ensure that heroal security doors meet the highest standards of burglary protection. These include burglar-resistant fittings, secure door panels, door hinges with side protection, our patented heroal profile composite to ensure extra stability, professional installation and the strength of aluminium.

Door construction - The patented heroal profile composite that we use between the aluminium half-shell and the insulation ensures particularly high stability and optimum burglary protection.
Door hinges with side protection - Door hinges connect the door leaf with the door frame. If they are too weak, the door leaf can easily be levered out. Door hinges with side guards make it considerably more difficult to lever out the door leaf.
Burglar-proof fittings - The more locking points, the more difficult it is to lever out the door leaf. heroal security front doors can be equipped with multiple locking systems. This offers particularly high burglar resistance combined with a high level of operating convenience.
Break-resistant door panels - All heroal security front doors can be combined with break-resistant panels, regardless of whether you opt for an insert, attachment panel or security glass.
Installation according to tested installation instructions - Without professional installation, the front door can easily be installed too far from the house wall. Our specialist partners ensure an optimum wall connection with no weak points.
Aluminium - heroal uses aluminium to achieve particularly high stability for our front doors.

Security doors withe tested burglary resistance

The safety and quality of heroal security doors are certified by the Institute for Window Technology (Institut für Fenstertechnik , ift-Rosenheim). There are many components in a security door that put burglary protection first – and they pose no restrictions in terms of dimensions and design. heroal aluminium security doors can achieve resistance classes RC 2 and RC 3 depending on their design.

Resistance class RC 3 means that no burglar can enter your house within 5 minutes using a screwdriver, crowbar or drilling tool. In more than 65% of door break-ins, the perpetrators break into the house by levering it open. If you have heroal security front doors in resistance class RC 3, those burglars do not stand a chance.

Resistance classes for security doors

Security doors in resistance class RC 2

Security doors in resistance class RC 2 (formerly WK 2) place high demands on components such as lock systems, door hinges and fittings. In addition, a safety glass certified in accordance with DIN EN 356 or an anti-break door panel is installed. Using simple lever tools such as screwdrivers, pliers or wedges, opportunistic burglars are unable to enter your home within a period of 3 minutes.

Security doors in resistance class RC 3

The individual door components used for security doors in resistance class RC 3 (formerly WK 3) are subject to higher demands. In addition, these doors use elements such as specially reinforced safety glass certified in accordance with DIN EN 356. Alternatively, the door can have break-resistant panels. Doors in this resistance class make it difficult to enter using other tools such as crowbars or drilling tools. Security doors in resistance class RC 3 withstand burglary attempts with such tools for up to 5 minutes. So even seasoned burglars do not stand a chance.
