A window wall

First and foremost are windows functional elements. But they also have a style-shaping effect. For both reasons, the position of a window in a building may not be as optimal at some point over time. Then a consideration is to close the window. In this guide you will learn what to pay attention to when you want to wall your window. Also, find out why you should not wall an old window.

The tasks of windows

Windows are significant elements on the facade of buildings. Windows have a number of primary but also secondary tasks:

  • weather protection
  • Protection against large temperature differences (inside, outside)
  • Regulation of room humidity
  • Regulation of room temperature
  • Brightness in rooms
  • architectural influence of the facade

The combination of these different requirements can result in a variety of arrangements on a building. So it may well be that a window precludes the determination of a room (for example, several windows in a bathroom) or even from a trend (symmetry of the facade, which is more or less important depending on the architectural style) was planned.

Can a window be simply bricked up?

Over the decades, it can happen that one or the other window is disturbing. Not infrequently, the homeowner then have the idea, the wall just zuzumauern. But one of the first questions that arises immediately is: is that even allowed? Then a simple answer can be given. You can brick up a window at any time without the permission of the authorities or a neighbor.

If a bricked window should be set later

However, if a window was originally set with the consent of a neighbor (for example in the case of border building), this declaration of consent may expire. Although this has no direct influence on it when you wall the window. If there is a need for a window later, it may need the new permission of the neighbor.

Do not underestimate the workload of bricking

However, bricking up a window can cause significant work that you should not underestimate:

  • plaster or cladding the inside of the facade (possibly including insulation)
  • plaster the facade
  • possibly a fitting or completion of a thermal insulation composite system (ETICS)
  • Repaint the interior wall as well as the facade

You may be able to combine the bricking of a window with other work such as painting the facade. For it is very difficult to adapt the walled and plastered window to an old façade painting. With existing thermal insulation systems, care must also be taken to ensure that no thermal bridge can arise at the junction between old and new ETICS.

Basic work while walling a window

Only the basic work, which always results in the demolition of an old window, remained. First you have to take out the old window. Also, the window frame, which is mounted in the window reveal, must be removed. Depending on the age of the window, the frame is fastened with window anchors with dowels as well as mounting foam or with dowel-free screws and adhesive tape. These are the changing assembly techniques for window and door assembly according to RAL that have changed over time.

Preserve lintel

Then the plaster is knocked off the soffit. Now the rows of walls can be continued as they were originally brought up to the window. The fall does not have to be taken out of the window opening. Depending on the requirements of the building, this could even have a negative effect on the statics. Now the window is bricked up, as every conventional wall is bricked. Then the bricked window is still insulated, plastered and painted according to requirements.

Tips & Tricks

Again and again, homeowners have the idea to simply disguise a window from the inside, for example with mounting plates or with plasterboard. So basically the walling of a window. From the outside, the window is mirrored and usually maintained. This is not a good solution, as moisture can enter quickly. From the inside, this can cause massive moisture damage to the building fabric.
