Today, every second apartment is decorated with an arch, or even more than one. More and more people tend to move away from interior doors in favor of open space. There is a tendency to move from complex arches to more primitive forms. The shape of the arched vault determines its name. The rectangular interior arch is one of the most popular.

Features of the
The arch is modern and fashionable. A rectangular arch, or as it is also called - a portal, of all forms and options is the easiest to install. For her, you do not have to radically change and adjust the doorway. The portal looks like the letter "P". The component of the portal is platbands, cornices and accessories. There are two types of arched doorway: passive and active.


A passive opening is a simple structure that separates rooms in an apartment. More complex arches that open a view of several rooms are called active. Portals are also divided into simple and complex. Stucco molding, decorative glass inserts, and carving make arched structures intricate. Their main difference from interior doors is that the doors separate the living space, while the arches, on the contrary, unite.
Arches are especially appreciated by owners of small apartments, because interior swing doors “eat up” a few meters.


The square arched opening is also a frequent guest in the design of the interior space. This is a good option for a room style where smooth lines do not prevail, and a rectangular option does not fit in width. The side supports of this square design can be decorated like shelves or glass inserts. Wooden arches made of wood with carved details are incredibly beautiful and majestic.


Interior portals are also relevant in the kitchen. This is a very convenient option for combining a kitchen and dining room or living room. For the kitchen, delights are not needed. Usually these are simple light arches made of drywall or wood. The rectangular portal is a good alternative to the kitchen door.
The only drawback in this design will be the smell from the kitchen throughout the apartment. But a powerful hood will make this disadvantage invisible.


A classic arch looks good when the height of the ceilings allows. If, after removing the interior door, you find a transverse concrete lintel above your head, then in no case should you break it. It is a load-bearing element to reinforce the wall. Then a high narrow arch will not work. A low arcuate arch looks unprofitable, which means that a rectangular version will come in handy. It happens that the arch is needed for technological indicators. Sometimes it may be necessary to reinforce the load-bearing wall when, for example, a door trick is cut through.
The arched structure conceals the result of the renovation and serves as a decorative function.


The portal must match the room setting. A dark wood opening in a light, light room will look strange, where even the armrests of the sofa are light. The presence of a cornice or curtain above the portal will give the impression of the heaviness of the structure. If you periodically need to isolate a room without an interior door, pay attention to a folding screen. This accessory is functional and in fashion again.
Variety of materials
Rectangular portals are most often made from drywall, foam, wood, brick or stone.
Most often found plasterboard structures. At the base there is a metal frame, drywall is attached to it. This type of arches is the most budgetary, besides, it is quite simple to install. It is a good choice in minimalist interiors where the doorway should not be a distraction. Such an arch can be supplemented with shelves, ceiling spotlights, and a niche.


Wooden arches they are particularly durable, they are practically not afraid of external factors. As a rule, such arches have wide cash boxes. Today, products are made from glued sawn timber. Such a structure is cheaper in cost than solid wood, but in quality it is not worse.
To prevent cracks from appearing on the arch from temperature and humidity changes, it must be treated with a special compound.


Arch made of stone created mainly from imitating lightweight materials. The materials serve as finishing of the finished portal. Natural stone is used only in private homes.


How to do it yourself?
Portals in place of interior doors add space and make the room visually larger.
You don't need to be a builder to install a portal to a doorway yourself. First of all, the old door frame is dismantled. If you cut the box beam in the middle, the dismantling process will speed up many times, the floors and walls will not suffer. Side edges of the portal will be formed from the additions for interior doors. It is important that the side walls are flat. If not, use plaster and corners. With the corners, it is easier to expose the edge of the opening so as not to reduce the extensions. It is important to set the first corner exactly in order to avoid further skewing of the entire structure.


The space between the corners must be filled with a solution and wait until it is completely dry. After that, by attaching the finish to the door and stepping back a few centimeters from above, a through hole is made using a drill. Dowel-nails are used for a concrete wall, and self-tapping screws for a gas silicate wall. First, the add-on is fixed at the top, bottom and then on the central holders. On the other side and on top, the extension is attached in exactly the same way. You can replace the self-tapping screws with assembly glue.

If you are sure of the accuracy of your calculations, then you can build a three-sided portal separately, then insert it into the doorway and put it on self-tapping screws.
