In most modern apartments, openings in capital walls have a rectangular shape. And many residents seeking to increase comfort have a desire to change the rectangular shape to arched. It is the arched form that is common in the apartments of improved layout, since it visually increases the doorways and gives the interior elegance. You can redo the doorway not only with the help of professionals, but also on your own. And you can do this in just a few hours. The whole procedure consists of four stages: the calculation of the parameters of the arch, the selection of the source materials, the creation of the arch, the installation of the arch in the opening. To properly determine the size of the arch, it should be noted over the door its top point and add five centimeters to this height. The source materials can be wooden, polystyrene foam, drywall. First, horizontal and vertical guides are attached in the doorway. Then the width and height of the doorway is measured, and these data are transferred to the source material, for example, to drywall. Next, the radius of the arch is determined, for which half the width of the doorway is taken. Using a jigsaw of drywall, two arches are cut out and using screws are installed on both sides on prepared horizontal and vertical guides. Now the turn of the slopes has come. For this purpose, a guide profile is taken, and marks are cut on it on the central and side. One side side is left whole. It is this side that the profile is screwed inward. It is attached around the circle on the inside of the sheet. The same is done on the back of the arch. After preparing the guides, the two halves of the arch are connected by installing a small section of the profile into the installed guides. At the end of the work, the arch needs to be thrown and painted.
