Leave your worries at the door
Inotherm security doors: no compromises
FOR THOSE WHO DON'T WANT TO LEAVE FRONT DOOR SECURITY TO CHANCE
First-class burglary protection is one of Inotherm's core commitments. Our aluminium entrance doors meet this commitment with robust construction and state-of-the-art security technologies as standard. With their quality, they have reliably protected almost half a million homes.
They also offer the highest level of energy efficiency, and you can customise the style to suit yourself.
COMPREHENSIVE PROTECTION AS STANDARD
Basic features include extra-thick aluminium plates, a 5-point locking system, security hinges and escutcheon, as well as cylinder protection.
FOR THE HIGHEST SAFETY STANDARDS
Our security packages of accessories are classified as RC2 and RC3 according to European standard EN 1627, thus achieving the highest level of protection for private premises.
ADVANCED, EASY LOCKING
Combine our security doors with the intelligent INOSMART system, which provides automatic locking and can be unlocked with a fingerprint, code or smartphone.
SECURITY IN STYLE, CUSTOMISED FOR YOU
Choose from over 400 security door models, each of which can be customised. Change the dimensions, colour, handles, glazing and much more.
EXCELLENT PERFORMANCE UNDER PRESSURE!
Inotherm security doors do not give in to brute force or tools used by burglars. The fact that only invited guests are allowed in is most eloquently illustrated by a particularly brutal attempted burglary.
Our door not only survived it, but also remained structurally intact! Despite the severe damage, it was still able to be unlocked and opened without any problems.
CHOOSE YOUR SECURITY DOOR
When looking for a security door that suits your needs and tastes, don’t just browse for one. Create it yourself!
Find inspiration in our virtual catalogue presenting over 400 models. With the online configurator, you can customise each one in your own unique style. Add transom lights and sidelights or a canopy, change the colour of the door leaf or the handle, choose unique accessories like a retro door knocker, and much, much more!
OUTSTANDING FRONT DOOR SECURITY ACCESSORIES – AS STANDARD!
5-POINT LOCKING SYSTEM
In addition to the centre latch, two additional latches, a solid hook and an additional pin ensure that the door is firmly fixed in the frame.
For easier unlocking, we have increased the distance between the cylinder and the edge of the door leaf as standard. At 45 mm, this is above average.
ABOVE-AVERAGE DOOR LEAF THICKNESS
The double-sided door leaf overlay measures 94 mm thick, with an aluminium plate on the exterior side that is 3 mm thicker than average.
This couples outstanding structural stability with a high level of protection.
SECURITY ESCUTCHEON OR LEVER HANDLE SET
An exterior and structurally integrated security escutcheon protects the cylinder area from drilling, while also serving an aesthetic function.
The security lever handle set is equipped with integrated protection to RC3 level.
CYLINDER WITH DOUBLE-SIDED OPERATION
Thanks to its bi-directional operation and security profile, the cylinder for the entrance door can be operated even when a key is already inserted on the other side of the door.
Each cylinder comes with 6 keys as standard.
3-PIECE SECURITY HINGES
Adjustable three-piece security door hinges protect the hinge side and prevent would-be burglars from simply ripping off the door leaf.
Security hinges are available in all three standard door colours, as well as the ten most popular shades of our aluminium security doors.
ADAPTABLE DESIGN
Whichever model you choose, Inotherm security door locks and fittings can be fully customised to meet your security requirements.
Every one of our doors is designed to be compatible with all the security accessories in our range, from intelligent unlocking to digital door viewers.
ACCESSORIES FOR EXTRA PROTECTION
SAFETY GLASS
Tempered safety glass (ESG) is impact-resistant and, in the event of breakage, shatters into small fragments that are not sharp, reducing the risk of injury.
An even higher level of front door security is provided by laminated safety glass (VSG) and glass with additional laminated layers (P4A or P5A). These types of glass consist of two or more layers with a special film between them. In the event of breakage, the glass fragments adhere to the foil, preventing both injury and break-in.
COPY-PROTECTED SECURITY CYLINDER
The cylindrical insert has several fixed and active pins to prevent cylinder drilling. The security cylinders also have a special security card to prevent the unauthorised copying of the keys.
In case of loss, additional keys can only be obtained from authorised workshops and by presenting this card.
MOTORISED LOCK
Combine burglary protection with maximum convenience. Our high-quality motorised security door locks automatically lock the door whenever you close it. So you have one less thing to worry about in your day – your entrance will always be securely locked.
WE MEET THE HIGHEST STANDARDS WITH DISTINCTION
Inotherm security doors are available with two certified security packages of accessories that comply with the European standard EN 1627 (Pedestrian doorsets, windows, curtain walling,
grilles and shutters - Burglar resistance - Requirements and classification), which classifies them in the RC2 and RC3 (RC – Resistance Class) protection classes.
RC2: RC2 security doors protect your entrance in particular against the opportunist burglar who uses everyday tools to break in. Most often, they try to open it with a screwdriver, pliers, wedges or small hand saws. The door must withstand such attempts for at least 3 minutes without yielding.

Inotherm's smart opening system INOSMART will make these worries a thing of the past!
THREE-WAY AUTOMATIC LOCKING AND UNLOCKING
With INOSMART, the door locks itself every time you close it. So all you have to do is unlock it. But rather than with a key, you have the option of three simple and practical methods:

Frequently asked questions (FAQ)
How can I make my home safe?
Experts point out that the most effective means of protecting against burglars tend to be very simple. Despite the common belief that security cameras or alarm systems are the best deterrents to burglars, recent studies have shown that the most effective solution is to install motion detector lights. The second most important thing is to have a good quality secure front door and secure windows.
What are the distinguishing features of a security front door?
Security doors are designed and built to withstand mechanical damage or tools used by burglars. In order to be rated as anti-burglary, entrance doors must have the relevant international certification. At EU level, the level of burglary protection is defined by the European standard EN 1627:2021 - Pedestrian doorsets, windows, curtain walling, grilles and shutters - Burglar resistance - Requirements and classification.
How do I choose the right security door?
When buying a security entrance door, you should pay attention to the level of anti-burglary protection (RC2 or RC3) provided by the security door locks and components, e.g. multi-point locking, security hinges, security escutcheon and impact-resistant glass. Quality of workmanship and thermal and acoustic insulation are also important. This way, you will not only keep burglars out, but also the cold and noise.
The security entrance door you choose should reflect your personal style and fit in with your daily routine. For example, if you value practical features, choose a fingerprint lock. But if security is particularly important to you, an Inotherm security door with RC3 protection is the right choice.
Is RC3 better than RC2?
Yes, RC3 security doors offer a higher level of protection than RC2 entrance doors. RC2 doors already offer a good level of protection, but we recommend RC3 for higher-risk buildings. Police and security experts recommend doors with a higher level of protection especially for buildings that have already been the target of a burglary or an attempted burglary, and for buildings in the vicinity of which a burglary has taken place.
What level of protection should I choose when buying a security door?
For the highest burglar protection for entrances to private premises, we recommend RC3 protection. Such doors can withstand at least 5 minutes of break-in attempts with more enhanced tools such as a combination of screwdrivers, crowbar and drill.
Which doors are the most secure?
The most secure front doors are those that are resistant both to physical force (blows and kicks) and to the various tools used by burglars (screwdrivers, saws, hammers, drills, wooden wedges, crowbars, etc.). High-quality security doors are equipped with multi-point locking, security hinges, impact-resistant glass, a security escutcheon and other security features.
The level of security provided by the door is determined by the classification according to the European standard EN 1627. According to this standard, the door is classified into six Resistance Classes, with RC3 being the highest level of protection for private premises. Although the method of manufacture and the security features are more important than the door material itself, it should be stressed that a quality aluminium security door provides excellent protection against burglars. They are structurally stable and strong, and when combined with the anti-burglary components we install at Inotherm, they can easily prevent even the most severe break-in attempts.
How much does a good quality security door cost?
Each of our security doors is unique, so we don't have a set price list. However, you can get a quote for your dream security door quickly and easily. We recommend that you select the desired model in the configurator, customise it to your liking and send us an enquiry. We will provide you with a personalised quotation as soon as possible.
