Doorway: dimensions and features of the box installation

Carrying out repairs, you need to carefullyapproach to various calculations. For example, the doorway dimensions may vary depending on the design of a particular room. Therefore, when replacing door structures, it is important to calculate everything competently. What should be taken into account?

Size matters

As you know, the doors - interior or entrance -play an important role in any interior. Accordingly, it is necessary to approach their installation correctly. In order not to get into a situation when you have to work on refining the wall finishes, you should determine in time what size of the doorway. Choosing designs, it should be remembered that different manufacturers offer different solutions. So, the majority of domestic and foreign brands offer systems under the doorway, the dimensions of which have a height of 2000 mm with a width of 600 mm to 800 mm. The designs of some manufacturers have a height of 1900 mm and a width of 550 mm. This varies the thickness of the boxes.

Possible problems and inconsistencies

Such a variety of solutions suggests that,choosing input designs, you need to take into account the parameters that the doorway has: dimensions and its design features. Otherwise, there may be several problems:

1. The unit simply does not stand in the doorway in the supporting wall, which will lead to the need to expand the opening.
2. Any increase is a huge amount of dusty and dirty work, during which the entire profile will undergo deformation. And this promises only extra time, nerves and money.
3. If you build a doorway, the dimensions of whichwere calculated incorrectly, you can also face the following problem: a wooden platband will not block the entrance in width or height, and this will affect the fact that you will have to perform some more work. Accordingly, it is also extra waste.

How to calculate?

So, to determine the size of the doorway entrance door, you need to proceed from the following indicators:

• width and height of the selected canvas;
• the thickness of the boxes and their widths;
• the width of the wooden trim;
• the presence of a wooden threshold.

Let's say your door has the following dimensions -2000 mm high and 800 mm wide with a box thickness of 25 mm. To determine the size of the opening, you need to add the width and thickness, plus the gap between the box and the door - about 20 mm on each side. That is, the ideal width will be about 880 mm. Under this opening will fit most of the models offered today. The height is calculated in the same way, only the top and bottom clearance is added to the height figure - it turns out 2050 mm for a door without a threshold and 2080 mm if the threshold is planned. As for the thickness, the most often offered are the designs of the door frame of 75 mm - they are designed for typical houses. However, there are exceptions to any rule, and therefore it may be necessary to dobore if the thickness of the walls of the opening is not the same.

Thus, the preparation and careful calculations of the doorway is a very demanding job that will allow installation to be carried out more correctly and quickly, and most importantly - without additional cash costs.
