Introduction for Security Doors RC4

En RC4-säkerhetsdörr är en högsäkerhetsdörr som uppfyller kraven för motståndsklass 4 (Säkerhetsdörrar RC4) enligt den europeiska standarden EN1627. Denna klassificering innebär att dörren klarar av en extra hög nivå av fysisk påverkan och inbrottsförsök.

The RC4 door consists of a heavy steel structure and is equipped with several different protective layers to ensure its strength and resistance. The door leaf is constructed from 2 mm steel plate in the door box and the faceplate is 3 mm thick. The door frame is reinforced with steel and the fixing points are protected to prevent tampering. It is also anchored to the wall with special anchor bolts and screws, making it difficult to pull the frame out of the wall.

The door leaf is equipped with several security features such as an additional and RC4 approved multi-point locking system and high security cylinder.

How long does an RC4 rated door resist a burglary attempt?

According to the standard, an RC4 door should be able to resist a burglary attempt for up to 30 minutes. This means an effective attack time of 10 minutes. When testing an RC4 door, it is assumed that the intruder has experience of burglary and will take more time. They also have access to heavier tools such as axes, saws, hammers, chisels and a battery-powered drill.

Despite a more experienced intruder with access to heavier tools, the door takes a relatively long time to open. This means that the door is designed and constructed to provide a high level of protection against burglary and allows enough time to alert security staff or the police.

Where do doors under the designation "RC4 security doors" occur and what are their uses?

The doors are widely used in all sorts of different contexts and are a good example of a high security door. They are found in industries, commercial buildings, warehouses and government buildings. Below are some examples of high-risk areas where they are more common than in other contexts.

RC4 security doors are designed to provide the highest level of security in high-risk areas where sensitive information or valuable assets must be protected. These doors are used in a variety of areas, from financial institutions and defense facilities to research laboratories and government buildings.

In the banking sector, for example, RC4 security doors are essential to protect customers' assets and money. These doors are designed to resist drilling, cutting and heavy impact, and have high fire resistance. They are available in different sizes and can be adapted to different needs, such as protecting large safes or smaller security compartments.

Another example is the defense sector where RC4 security doors are used to protect high-tech equipment, weapons and sensitive information. The door thus creates a secure location for defense equipment and protects against espionage and sabotage. In many cases, a high-grade door like RC4 is a regulatory requirement for these types of facilities.

In the field of research, RC4 security doors are used in laboratories where hazardous substances or dangerous experiments are carried out. These doors are designed to withstand high temperatures and the risk of explosion, minimizing the level of risk to researchers.

RC4 security doors are also common in government buildings where sensitive information and documents need to be protected. These doors are used to protect against unauthorized access, theft and data breaches.

Overall, RC4 security doors are used in a variety of high-risk areas where the highest level of security is necessary. These doors provide a reliable and effective solution for protecting sensitive information, valuable assets and lives.

Why choose an RC4 instead of an RC3?

RC4 doors have several advantages over RC3 doors. Here are the main and most distinctive advantages of RC4 doors:

Higher level of security: RC4 doors offer a higher level of security than RC3 doors. They are designed to resist more sophisticated burglary attempts and can provide an extra layer of protection for people and property. Higher requirements include locking systems and the material and thickness of the door leaf, which is an important factor.

More time to call the police and emergency services: One of the major differences is that an RC4 door has 30 minutes instead of 20 minutes of attack time during security testing. This gives you extra valuable time to repel the attack before the situation becomes critical or potentially life-threatening.

Increased durability: RC4 doors are more robust and durable than RC3 doors. They are made with high-quality materials and have been designed to withstand higher stresses, making them ideal for use in high-risk environments.

Better insulation: RC4 doors have better insulation properties than RC3 doors. They are designed to minimize energy loss and maintain a consistent indoor temperature, which can lead to lower energy costs and a more comfortable environment.

Other benefits

Another advantage of RC4 doors is that they can offer higher protection against fire compared to RC3 and RC2 doors. This is because RC4 doors are often made of materials with higher fire resistance, which reduces the risk of fire penetration.

A further advantage of RC4 doors is their flexibility in terms of design. The RC4 rating is available for a wide range of doors, from standard external doors to fire doors and balcony doors. This allows users to choose an RC4 door that suits their specific needs and security requirements.

Is the glass in my RC4 really safe?

Yes, the glass in RC4 security doors is safe and is specially manufactured to meet high security requirements. When manufacturing RC4 security doors, the glass is an important factor to consider in order to achieve the highest possible security. MaxiDoor builds its security doors with bulletproof and advanced ballistic protection glass BR6NS/FB7NS. The glass also has explosion class EXR5NS. The doors can also be reinforced with polycabonate or laminate.

Using reinforced glass reduces the risk of intruders entering the door by smashing or breaking the glass. As well as providing greater security, it also helps to increase energy efficiency and reduce sound transmission. Insulated glass can also be used in RC4 doors to further improve the sound and thermal efficiency of the doors.

In summary, the glass in RC4 security doors is an important factor in achieving the highest possible level of security. In addition, glass in doors can provide better visibility and communication between different areas of the workplace, which can increase collaboration and reduce the risk of accidents and injuries. Glass in doors can also help create a more open and inviting atmosphere in the workplace, which can improve the well-being and motivation of employees.

Examples of door types

RC4 security doors are used in different types of doors, depending on the needs of the organization or individual. The most common types of RC4-rated doors can be used for example for exterior doors, fire doors, balcony doors or entrance doors.

RC4-rated external doors are often used to protect against burglary and other external threats. These doors can be installed in both private homes and commercial properties. RC4 doors are not yet the most common for residential front doors. They belong to the category of the most secure and affordable doors that can be installed for a residence.

RC4 rated fire doors can be used to provide both fire and burglary protection. These doors can be particularly important in public buildings or commercial properties where it is important to ensure that people can be safely evacuated in an emergency. As an RC4 door has a more robust construction, it provides extra protection in the event of a fire.
Balcony or patio doors can also be installed with an RC4 rating to provide extra protection for apartments or villas. These doors can be particularly important for people living on the ground floor or ground level, thus having a higher vulnerability to intrusion.

Entrance doors are one of the most common door types to have an RC4 rating. The reason is that for many businesses they act as the outer shell and in many cases are the only obvious way to enter the building. It is not uncommon to place the highest ratings on the outer shell of the building, and then lower the ratings on internal doors. An entrance door or entrance section is also usually made with large open glass sections for aesthetic and practical reasons.

A good choice

In summary, RC4 doors offer higher levels of burglary protection, better protection against fire and a flexibility in design that makes them a popular choice for both businesses and individuals seeking the highest level of security for their homes and premises.
