The nurses from the newly built hospital in Aachen were amazed at the reference in the late 1980s, when they wanted to test the building: The doors in the brand new high-tech complex were sometimes too narrow for the beds. This shows how important good and complete planning is. Only then is one protected from evil surprises. Compliance with standard dimensions is very helpful.

Standardization to keep prices under control

The biggest advantage of standard dimensions is that they allow mass production. Only standardized dimensions make it possible to produce door leaves, frames and frames in large quantities. For this reason, only the carpenter produces single-component production at a multiple of the price of a standard door. However, the planning of standard doors above all requires that the construction workers also stick to the standard dimensions in the bodyshell. It does not help the greatest standard door, if the frame does not fit into the opening of the wall afterwards.

Always check the shell dimensions!

Here is a tip for aspiring builders: Be sure to measure the door openings accurately! A good bricklayer learns while teaching, as the door opening has to look for a standard door. However, one never knows which workers are currently hired by the subcontractor. If there are many doors in the house, it is worth making a template. Simply four boards are screwed into a rectangle and stiffened with a diagonal strut. The external dimensions of the rectangle should correspond exactly to the raw construction dimensions. If the template fits through the door, everything is fine. If you do not fit, you have to work as early as possible. In most cases, a hammer and chisel or an angle grinder are enough to remove a crooked stone so far that the rough construction is made. But you should not wait until the decorators have laid the floor. The best time for control is immediately after pouring the false ceiling. Now accumulating dirt and grit from adjusting the openings can still do no damage to the interior.

Components of a door

A door always consists of four components:

  • Door leaf with lock
  • door frame
  • doorframe
  • Fittings and hinges

The door leaf is a flat rectangle of wood or other suitable building materials. High quality doors are made of solid wood. Inexpensive standard doors from the hardware store consist of coated or printed fibers. Heavy solid wood doors have the advantage that they also isolate the sound well. The inexpensive lightweight doors are usually not that good.

The door frame covers the inner reveal of the wall. It depends the most on the observance of the norms in the construction of the building.

The door frame hides the gap between the frame and masonry. The lock and the hinges are also attached to it, in which the door is hung. Here should be planned very carefully. It has quickly installed a wrong-opening door. As with any building activity, the same applies to the installation of door frames: Measure three times - execute once!

Components of standard door frame and frame

The shell dimension should be about 5 mm larger on the side than it has the dimensions of the standard door frame. This ensures both a good fit and good anchorability. For a skilled mason 5 millimeters are a very large tolerance that he can easily comply.

The first standard dimension - is important for the frame: It is the width of the wall.

The standard dimensions for the thickness of exposed walls are 11.5 cm, 17.5 cm, 24 cm, 30 cm and 36.5 cm. For the plaster you have to expect on both sides with 5-10 millimeters surcharge. The extremely wide walls are usually found only in the basement. Basically, walls up to 11.5 cm are not supportive. This makes retrofitting a door in these walls particularly easy. From 17.5 cm, a wall can be designed to be load-bearing. Any measure of it is definitely a load-bearing wall. Subsequent breakthroughs for doors are very dangerous and should be planned expertly. It can jeopardize the whole statics of the house up to the collapse, if it is too carelessly supported.

Frame and frame are finally standardized in the width of the door opening.

The standard measure - applies today to "Folded doors" and "Unfolded doors". Folded doors are doors with a peripheral double edge. This construction has gained acceptance, as it is the most reliable way of preventing wind from passing through. For many doors, the inner rebate is additionally sealed with a Dämmband.

Standard dimensions according to DIN ISO 18101

The standard dimensions for door frames are regulated in DIN ISO 18101.

wall thickness

The DIN ISO 18101 is based in the thickness of the walls not on Rohbaumaß, but on the finished plastered, ready for doors wall. For this purpose it specifies the following dimensions:

Lightweight / drywall:

  • 80 mm standard dimension - 75 - 95 mm tolerance for wall thickness compensation
  • 100 mm standard dimension - 95 - 115 mm tolerance for wall thickness compensation

Normal, single-shell, non-load-bearing walls:

  • 125 mm Standard dimension - 115 - 135 mm Tolerance for wall thickness compensation
  • 145 mm Standard dimension - 135 - 155 mm Tolerance for wall thickness compensation
  • 165 mm Standard dimension - 155 - 175 mm Tolerance for wall thickness compensation

Potentially supporting walls (possibly suitable for increased sound / fire protection):

  • 185 mm standard dimension - 175 - 195 mm Tolerance for wall thickness compensation
  • 205 mm standard dimension - 195 - 215 mm Tolerance for wall thickness compensation
  • 225 mm standard dimension - 215 - 235 mm tolerance for wall thickness compensation
  • 245 mm standard dimension - 235 - 255 mm tolerance for wall thickness compensation

Load-bearing masonry:

  • 270 mm standard dimension - 260 - 280 mm Tolerance for wall thickness compensation
  • 290 mm standard dimension - 280 - 300 mm tolerance for wall thickness compensation
  • 310 mm Standard dimension - 300 - 320 mm Tolerance for wall thickness compensation
  • 330 mm standard dimension - 320 - 340 mm tolerance for wall thickness compensation
  • 380 mm standard dimension - 370 - 390 mm tolerance for wall thickness compensation

How to measure a door opening in the shell "> The pre-measurement should take place as soon as possible after the erection of the masonry.This is the best way to determine whether the bricklayer measured or confused the measure.A final measurement is ideal after the introduction of the ground leveling you also get the right height from the doorway.

  • The width is simply measured at the finished wall opening.
  • The height is measured from the upper edge of the finished floor (screed) to the lower edge of the lintel.
  • The soffit is measured after plastering, from outer edge to outer edge. It is important that a possibly planned tiling is also included.

If no floor covering such as parquet, laminate or PVC has yet been added, a preshocking is still quite easy. In the falls but you have only a few millimeters of air for straining. These are load-bearing components with an integrated reinforcement. You must not break, otherwise the statics in this point is no longer guaranteed.

Prices for door frames and frames

The prices for doorframes and frames vary widely. As with the door leaves, especially the choice of materials for the price of a door frame is responsible. The prices start at very cheap models at about 80 euros. There are no limits to the top. In the basement mainly steel frames are installed. The same is mandatory for fire doors. Steel frames cost in the narrowest version from 50 euros. However, high-quality painted steel sheets can cost up to 280 euros or more.

In the real wood frames, the beech models are particularly inexpensive. For a new frame you have to expect about 120 euros. Structure oak already costs from about 180 euros. For a solid wood frame of cherry, however, can already be estimated 450 euros. However, a high-quality equipment of a house also contributes significantly to its increase in value. After all, you want to feel comfortable in your own home. A consistent "always as cheap as possible" equipment certainly does not contribute to a real feel-good climate. But a little luxury and value can change this in a sustainable way.
