When talking about doors, it is essential to consider both performance and dimensional indications , to ensure safety, functionality and accessibility. These aspects are described in detail in the Ministerial Decree 236 of 1989 , which at point 4.1.1 establishes precise requirements to ensure that the frames are suitable for use also by people in wheelchairs.
Let's look at these issues in more detail, with a particular focus on the classes of armoured doors .
Performance Indications
Accessibility and Maneuverability
The access doors of each environmental unit must be easily maneuverable . This means that the door, including the compartment and the surrounding spaces, must be designed to allow easy transit even for people in wheelchairs. The spaces in front and behind the frame must be coplanar and sized adequately for the necessary maneuvers.
Types of Doors and Handles
To facilitate opening and closing from both sides, sliding or folding doors are recommended. On the contrary, revolving doors, non-delayed automatic return doors and glass doors without adequate safety measures should be avoided. Glass doors , in this regard, must be easily identifiable through appropriate signs to avoid accidents.
Furthermore, door handles should preferably be of the lever type, curved and rounded , positioned at a height between 85 and 95 cm, with a recommended height of 90 cm.
Differences in Level and Renovations
In the case of renovations or for access doors of real estate units, differences in level are permitted, provided they are limited and such as not to hinder the passage of a person in a wheelchair. This flexibility allows existing structures to be adapted without compromising overall accessibility.
Dimensional Indications
The dimensional indications for the doors are precise:
- The clear width of the access door of each building and each real estate unit must be at least 80 cm .
- The clear width of the other doors must be at least 75 cm .
These measures ensure that the doors are wide enough to allow easy passage, even with mobility aids.
Differences between Class 3 and Class 4 for Security Doors
When choosing armored doors, it is essential to understand the differences between the various security classes . In particular, class 3 and class 4 represent two different levels of resistance :
- Class 3 : Offers good resistance to attacks by expert thieves. These doors are suitable for homes in urban areas or for those who want a medium-high level of security .
- Class 4 : Provides a higher level of security, resistant to break-in attempts with heavy and sophisticated tools. These doors are ideal for homes in isolated areas or for those who require high protection .
The decision between a class 3 and a class 4 security door depends on several factors , mainly the location of your home. A class 4 security door is particularly suitable for those who live in isolated homes or in contexts that require a higher level of security. However, for those who live in an apartment building or a terraced house , a class 3 security door is generally sufficient.
In terms of price, a class 3 security door ranges between €1,800 and €3,700 , while a class 4 one varies between €2,200 and €6,500 .
