According to the standards EN 12210 and EN 12211, doors are tested for their resistance to wind. In these tests, the door is repeatedly subjected to increasing pressure in both directions to simulate the effect of strong winds.
It is important that the door remains stable and that no parts such as panes, door closers or handles are torn from their anchorage.
The resistance of doors to wind loads is divided into different classes according to the DIN EN 12210 standard, depending on the requirements of the building and the location. The classification ranges from class 1 to class 5, with higher classes representing higher wind loads.
The specific requirements are:
There are also special classifications (Exxxx) for doors that must withstand even higher loads than the regular classes.
Another important aspect in the assessment of wind load resistance is the deformation criteria. These determine how much a door can deform under wind load without its function being impaired.
The deformation is measured in terms of the relative frontal deflection and divided into classes:
Rainproof doors offer optimal protection for buildings exposed to severe weather conditions by preventing water from entering the interior due to wind pressure. These doors are made of durable materials and are designed to withstand heavy rainfall and wind loads.
The driving rain tightness is tested according to the European standard EN 12208, in which the building element is exposed to both rain and pressure under controlled conditions. Doors are divided into classes that determine their resistance to water and wind. The test process simulates different wind strengths and rain conditions to ensure that the building element is reliably protected against water ingress. At Hodapp, a special focus is placed on robust seals and a well-thought-out design to ensure the highest level of tightness.
Rainproof doors are particularly essential in the construction industry, as exposure to wind and rain poses a challenge in many climates. High-quality doors that meet the test requirements of EN 12208 contribute to long-term building safety, prevent moisture damage and at the same time increase energy efficiency.
Airtight doors are critical to the efficiency of buildings and specific applications where air exchange must be minimized. They prevent unwanted airflow between rooms, which not only optimizes energy efficiency but also helps prevent air pollution and dust in controlled environments such as the chemical and nuclear industries. These doors are particularly valuable for maintaining the cleanliness of rooms, for example in the production of pharmaceuticals or in research facilities. They also help ensure proper air circulation in complex HVAC systems.
Airtight doors are particularly relevant for special applications such as laboratories, clean rooms or industrial buildings where overpressure is required. By minimizing air permeability, the penetration of pollutants and dangerous particles is also prevented.
Airtightness testing according to EN 12207 is an essential part of accurately measuring door performance. It ensures that doors perform optimally when subjected to the stresses of demanding environments, whether it is energy use, maintaining pressure conditions or preventing harmful substances.
Every construction project has its own characteristics and the right solution depends on numerous aspects.
