A large selection of interior doors makes it possible to purchase a structure to your taste, various designs, high strength, with good heat or sound insulating properties. There are designs that suit most requirements. These are interior doors with a protruding strip around the perimeter. You need to know what a porch is, what are its features that affect the installation.
What is a narthex of a door: its features
If you look closely at the design, you will notice that when closing the door with a vestibule, part of the canvas has a protrusion that is superimposed on the box. What is a narthex and how is it different? This is a thin rail protruding around the perimeter of the door leaf and going into the door frame. Its thickness is 4 times less than that of the main canvas. In this regard, the design is called the door to the quarter.
Previously, the narthex was used in structures made of solid wood. Now it can be found in other models made, for example, from MDF, as well as in plastic constructions or in armored entry mechanisms.
Advantages and disadvantages of products
Due to the presence of a single or double protrusion at the door there are no gaps and gaps between the box and the canvas when it is closed. A mock plank allows you to achieve a perfect fit between them.
Therefore, such models are in demand for a long time. Advantages of doors with a narthex.
- Quality soundproofing. The pretended plank creates the necessary tightness of the closed door due to the tight pressure on the box. It is especially necessary in the study, bedroom and nursery, where extraneous noise often interferes.
- The protrusion does not allow draft, cold air, dust and moisture. For greater tightness, it is glued inside with a sealant. Doors of this kind are often used as entrance doors in the kitchen and in the bathroom.
- Disguise clearances. After mounting, uneven gaps may form between the web and the frame, worsening the appearance. The narthex hides them and is a decorative element.
A mock bar creates some cons:
- The complexity of manufacturing and installation makes doors more expensive than other types of models.
- Installation requires professionalism, since high-quality installation of the structure is not available to everyone.
- The presence of the narthex makes the door seemingly massive, visually hiding the space. It is preferable to install it in a large room.
- Products require special screw-type fittings. The installation process is complicated, but the hinges become invisible.
How to choose interior doors with a narthex?
When buying doors, you should pay attention to some details. The pretended plank should be flat, without defects, without bevels and curvature. The seal must not prevent the door from opening or closing.
Like ordinary doors, the most common swing structures are: blind, with glass, with one or two wings. They are quite affordable and look attractive. The sealant must not make loud noises. If it starts to stick when closing, it is wiped with a damp cloth or degreased.
Entrance door designs
The system with a vestibule is located in the doorway and consists of a duct and a door leaf with a profile strapping. Roughnesses of walls are hidden by platbands. Door panels are held by two or three side hinges. The canvas can be left or right. On the corresponding side, loops are mounted on it. If necessary, a threshold is used in the design of swing doors .
Hardware Features
The technology of mounting the door in the presence of the vestibule is no different from the usual one, except for the hinges. Here, the fittings have distinctive features when the axis moves when turning. The hinges for the doors with the narthex are as follows.
- Card angular. These are mounting plates bent at an angle of 90 °. They are installed similarly to direct loops: one part is fixed on the edge of the hole, and the other is attached to the edge of the canvas.
- Screwdrivers. Such loops consist of two hinges, on each of which a screw pin and a pin are fixed. They are attached obliquely to the canvas.
- Hidden hinges - a complex structure containing hinges closed by a metal casing, a lever and a screw connecting movable elements. The hardware is invisible with the door closed. The canvas opens to a wide angle. The insert is done carefully using a milling saw. Hidden loops may contain a closer.
Doors with vestibule and screw hinges can be assembled at the enterprise together with the frame. This facilitates their installation in the apartment. The reliable operation of the doors depends on how correctly the hinge with the narthex is selected. If they are taken weak and poorly installed, problems will subsequently arise. Hinges are made of stainless steel and brass. The latter are quite reliable and resistant to corrosion. If greater strength is required, stainless steel products are used. Their drawback is one color that may not fit the interior.
Pay attention to the number of mounting holes. Four are enough for lightweight MDF doors, and 5-hole hinges are chosen for solid wood.
Do all have a porch door?
The most affordable prices for laminated doors. The film imitates any coatings and has great resistance to moisture and aggressive environment. Affordable cost at Finnish doors, which have a strict style and high quality workmanship.
Many models are sold complete with door frames where hinges and locks are already installed. In general, the design is cheaper. Installation is also greatly simplified. If you take products with a double shutter, their useful properties increase due to an additional sealing circuit. It is important here that the effect of the spring is small, since the doors are more difficult to close.
Rules for combining doors with the room
When choosing a door, determine what the model will include:
- material - plastic, wood, MDF;
- type of canvas - drawing, partitions, glass inserts;
- type of fittings.
The narthex gives the door a massive look. To gain lightness, they make glass inserts that combine with many interior styles. In small rooms, single-door structures are used. For the living room, the largest room with a wide aperture is usually allocated. A double door is best suited here .
Door mounting
The box is installed in the same way as with ordinary doors, only special hinges are screwed into its rack. Their thread should fully enter the body of the box. In the future, they can be adjusted.
The mating parts of the hinge are screwed into the door leaf. Then the hinges on the stand and the door leaf are combined, and the opening and closing of the door is checked. After the border of the canvas is marked on the counter, taking into account the gap that should be between the canvas and the floor (at least 10 mm). Then the box is mounted in the opening, and the canvas is hung. The gaps between it and the box are regulated by twisting the loops. Their special design with an axis offset allows you to freely open the door. At the same time, the narthex of the door leaf will not rest against the box.
Conclusion
If the owner of the apartment does not know what a narthex is, for installing doors it is advisable to seek help from specialists because of the complexity of the design. In this case, special loops are used, requiring the presence of skills during installation. As already mentioned, such a design better protects against penetration, looks spectacular, and also has heat and sound insulating properties.
