Points to be considered when choosing the type of door

Choosing the appropriate type of door in your current or new project is important as much as choosing all the other components. Points such as the potential temperature to be maintained, the temperature difference between indoor and outdoor space, the sizes of the carrying system, opening and closing frequency, doorsill details, quality of the panel/wall to be assembled, operational areas suitable for the door to function, compatibility of the door with the existing passing system are critical issues to be considered when choosing the type of door.

Well, do you choose a door according to your needs or do you choose the door and then adjust to your needs?

What we typically experience is that first a door is chosen and then its compatibility with the need is evaluated. However, some basic questions should be answered at the beginning and the type of the door should be chosen in accordance. For instance; a larger door which is not compatible with your needs means, first of all, more purchase cost, difficulty of use and unnecessary energy losses during the operation. On the other hand, a smaller door would increase your service costs after sale, since it will cause operational accidents. The automation system may seem as high-quality, but you may use so rare that it isn’t worth that cost. You may order unnecessary accessories for your doors or you may reduce your service costs after sale by ordering very simple protective accessories.

How do basic questions and answers direct us when choosing the suitable door?

You can examine below how some basic questions and their answers direct us when choosing the type of door.

Question: What are the properties of the environment in which the relevant room is opened?

For example, the potential temperature to be maintained should be -5C° and above. If this door is opened to an external environment or to a corridor at room temperature, we recommend the blade thickness to be 9 cm. If it faces a corridor with a potential temperature of +5C°, 7cm-thickness will also provide the same insulation level. The atmospheric conditions of the external environment are also important to specify other details of the door. For example, if it is opened to a very humid environment, icing and/or sweating may be experienced during pass and exits, so resistance inside the gasket and ground resistance can be used to prevent this. If necessary, oil-filled doorsill heater can be recommended in order to prevent freezing. This door may be exposed to external environment conditions such as sun, rain etc. with respect to the environment it will be opened to. In order to reduce the negative effects of external environment conditions, suitable accessories can be used and added on the door.

Question: Which part of the environment and location does the door open to?

Some development suggestions can be offered according to the environment which the door is opened to and with respect to the location of the door, if necessary. For example, a design can be developed by taking forklift and transportable working platforms into consideration. For example, the door should be wide enough to enable the faster forklifts move easily. However, a narrower passage can be chosen for a forklift that moves relatively in a straight corridor.

Question: What is the potential temperature to be maintained and the temperature difference between environments?

Basically, potential temperature to be maintained and temperature difference help determining the door thickness. At the same time, it supports the selection of the icing inhibitor accessories to be used on the door. If there isn’t a ground heating system on the doorsill at -40C° and below room temperatures, oil-filled doorsill passage and resistance system inside the gasket should be made. If there is a humid environment, case gasket system can also be applied in addition.
