Repair - it is a very complicated process that requires attention and a responsible approach.To achieve the desired result quality by following a specific sequence of actions.For finishing floors and walls precedes installation of interior doors, which are one of the most functional and aesthetic elements of the interior.


Options doorways ↑

Special attentioninstallation of doors should be paid to the doorway, his size, configuration and number of other parameters.The fact that it must be defined in advance with the dimensions in order to avoid undesirable situations when necessary to order custom doors or engage additional finishing the walls.Obviously, in this case doors and repair the whole premises owner cost significantly more than might be.

It should be noted that at present the manufacturers of interior doors offer consumers a huge number of the

most different variations.Most of them have standard dimensions:

- door height is 2000 mm;

- width can be equal to 600 mm, 700 mm or 800 mm.

However, some manufacturers are products of a width equal to 550 mm, and height - 1900 mm.Furthermore, it varies not only these parameters but also the width of the door frame - from 15 mm to 45 mm.

These data are extremely important when determining the size of the door opening, which will be installed in interior doors.In the case of neglect of these parameters may be a situation where the door frame just did not fit into the existing opening, which would entail the expansion and additional costs.Moreover, the presence of any utilities, plasterboard walls with a metal frame and complicate the process of expanding the opening.

downside would be the situation where the doorway is too large for the door.The narrowing of the opening will also entail the need to appeal to the civil organization and spending.

Sizing interior door ↑

Calculate the correct size required can be the doorway, knowing a number of parameters:

  • desired height of the door leaf, its width;
  • thickness and width of the door frame;
  • width casings;
  • the presence and size of the threshold.

Example of calculating the dimensions of the door: height and width ↑

As an example, the following calculation.The size of the desired door leaf is 2000 * 800mm, and the thickness of the door frame - 25 mm.Calculate the size required for such an interior door opening can be, adding to the thickness of the width of the door of the box.It should take into account that the latter figure is the case on both sides, so the thickness of the box is added twice.Furthermore, the calculation should take into account and necessary assembly clearances is about 15-20 mm on either side.Thus, the formula for calculating the size of the opening is the following amount:

800 + 25 + 25 + 15 + 15 = 880 (mm)

The width of the door opening

width of the doorway 800 mm is almost perfectfor the majority of manufacturers of interior doors.These doors are easy to install in standard size doorways premises.

opening height is calculated similarly, depending on the availability threshold and mounting clearances.For this adjustment to the added thickness of the door panel of the box, the gap size (10-20 mm).

Total height of the doorway is:

2 000 + 25 + 10 + 15 = 2050 (mm)

From this we can conclude that for the door leaf, which measures 2000 * 800 mm, the wall opening musthave dimensions of 2050 * 880 mm.

thickness doorway ↑

Also width and height, a doorway characterized by even thickness.In typical homes standard doorways, more precisely, their thickness is 75 mm.For this reason, manufacturers of interior doors offer the consumer the doorframes of the same thickness.This is sure to be taken into account when installing the door.Otherwise, we can talk about installing extender box or sipped along.If you do not take these measures, then install casings can be problematic and lead to an unattractive appearance of the door.

to determine the parameters wall is recommended to measure the thickness at three (at least) the points on all sides.At the same parameters on the perimeter of the doorway will have to carry out an order of non-standard interior doors.If the thickness at these points are different, it is necessary to cut the door frame, and in some cases put transoms.The fact that non-uniform thickness indicates the curvature of the wall.If you do not take the necessary measures, it will not be possible to establish quality frames.

Installing the door frame with transoms

Thus, at present, there are certain standards of doorways.Competent approach to the measurement of the parameters of the opening, the calculation of its optimal size based on the desired size of the door leaf, a number of other nuances - all it allows high-quality and reliable installation of interior doors that will last more than one year.It will delight the home owners and their guests not only for its functionality and security, but also the aesthetic appearance, which is largely achieved with proper installation.
