What is a door frame: types, materials, components

Interstate standards for the sizes of cardboard boxes were adopted on January 1, 2008 (GOST 12301-2006). They are used in the manufacture of paper and cardboard packaging for food and non-food products.

The document contains basic terms, definitions, standard parameters of boxes, manufacturing materials. In addition to the Russian Federation, the standard has been adopted in countries such as Moldova, Tajikistan, Uzbekistan, Belarus, Ukraine, Azerbaijan and others.

What is a door frame?

The frame is part of the door block. It is used in swing-type models; the sash is suspended from hinges. Install the entrance or interior door frame into the opening on the wall. The most popular material for making boxes is solid wood. A cheaper option is MDF and other combinations of wood waste. Ludki can have threaded grooves on the end intended for fixing platbands and extensions.

The hidden door frame is hidden when installed in the wall; it is made of aluminum. Even the hinges remain invisible.

The door frame design involves the use of three or four elements. U-shaped boats without a threshold consist of two posts connected at the top by a crossbar. In a full-fledged boat, the fourth element is the threshold. Such frames are required when installing a door block in a bathroom or at the entrance to a room.

Boxes are usually sold as a set with accessories and platbands. Additional elements help to refine the doorway. The structure of the bowel differs according to the following characteristics:

with or without extras;
with telescopic platbands or strips without grooves;
with or without a seal;
with overhead or mortise fittings.

A box with telescopic platbands, as well as one equipped with a seal, is considered convenient to install and use.

What nuances should you consider when choosing a box?

A typical mistake when measuring an opening is ignoring the thickness of the walls. But to correctly select the moldings, it is not enough to know only the width and height of the opening. If you do not take into account the thickness of the wall, the door frame will protrude beyond the front plane of the walls or, conversely, will be recessed into the opening.

In addition, it is important to determine the optimal position of the door leaf. It can be slightly recessed into the opening or placed flush with the trim. The configuration of the molded elements depends on this, since the boxes are ordinary and coplanar. It is the second option that ensures the canvas is positioned in the same plane with the platbands.

Box sizes

The consumer is offered different sizes of door frames, depending on the location of their installation. Dimensions are maintained according to the standard. It differs for manufacturers from different countries. The most common standard door frame size for interior doors from a domestic manufacturer coincides with products from Finland, Italy and a number of other European countries.

The standard size is:

sash width – 55, 60, 70, 80 and 90 cm;
sash height – 190, 200 and 210 cm;
box thickness – from 2 to 7.5 cm.

This thickness of the interior door frame was determined for good reason. The size variation is due to different wall parameters.

The optimal depth for the door frame of an interior door is 7.5 cm. The frame is suitable for walls made of plasterboard or brick. For thick partitions made of other materials, boxes 10 cm wide are produced. There are imported boxes with a depth of up to 20.5 cm.

The total height and width of the door frame of the interior door is determined taking into account the size of the leaf. The thickness of the pan is added to the dimensions of the canvas. It will be clearer with an example. Let's take a canvas 60*200 cm and a frame 7.5 cm thick. As a result of the calculations, the total width of the door with the frame will be 67.5 cm, and the height will be 207.5 cm.

The size table will help you determine the dimensions of the interior door frame.

How to calculate values for an opening using measurements

The opening does not always comply with GOST or another standard. Then you have to measure them. Each parameter has its own scheme.

The height is measured from the lowest point on the floor (if there is a baseboard, it must be taken into account) to the highest. The opening can be uneven, then measurements begin in the narrowing area and go to the casing;

Width is measured based on height

It is important to note that the measurement is not taken from the top, but exactly in the middle - the height is divided in half and measured from the center point of the right casing to the center point of the left. Again, if the opening is uneven, the narrowing is also fixed;

The depth is measured from above and below and in the center, the maximum value is found and then based only on it.

Types of boxes

There are different types of door frames based on design, material and other parameters. The boat, consisting of three or four elements, has the following methods of connecting the racks to the crossbar:

Spiked. The door frame timber is joined using a tongue-and-groove lock. The method is complex, but reliable.

Baguette. The edges of the timber are cut at an angle of 45º. The elements are connected using hardware.

Right angle. Before joining at an angle of 90°, grooves are cut at the end of the beam, removing part of the quarter.

Of all the options, the design of a door frame with a right angle is considered simple.

The structure of the bows differs according to the type of fastening of the extensions and platbands :

The simple one comes without grooves. Extensions and trims are fixed with glue, nails or self-tapping screws.

The telescopic door frame is equipped with special grooves into which extensions and trims are attached.

Monoblock. Innovative design. The box and platbands are one whole.

The advantage of the monoblock telescopic box is that it is fully equipped. You don’t have to buy additional trims and platbands separately.

According to the design of the boat, there are three types:

Encompassing. The structure consists of a frame, extensions and platbands. The door frame is supplied with a seal. Cheap options may not have extras. The planks will have to be purchased separately.
End The boat is designed for mounting on a special metal frame. Used when arranging openings for thin walls made of plasterboard.
Corner. Ludka is considered universal. The frame with the platband is connected into a single structure. During installation, a seal must be installed.

Separately, it is worth considering the hidden door frame, which is completely hidden along with the hinges in the wall during installation. The entire block is made of aluminum and comes in two types:

Ready box . The door has a laminated, enameled or other coating. Installation of mirrors is allowed.
Boat for finishing . The canvas is covered with a layer of primer. After installing the block, it is subject to further finishing with wallpaper, painting or cladding with other materials.

The handles on the sash are also made hidden. Usually it is a slot on the canvas or a magnetic device.

Materials

The pots differ according to the material they are made of:

The most common, inexpensive and durable are wooden door frames . During installation, products made from untreated timber are impregnated with an antiseptic and opened with varnish or paint. For a budget option, the boxes use solid pine . The technology of manufacturing from spliced timber allows you to get rid of wood defects. The frame elements are glued together from small blanks.

Door frames of MDF, fiberboard and HDF . Frames are covered with laminate, veneer and other materials that protect the product from moisture and also make it attractive. Layered composites have excellent characteristics. The material alternates layers of wood waste with plastic.

A special aluminum frame for a glass door comes with a seal and a set of corners. Ludka is installed in glass openings of offices and other organizations. Fixation occurs with pressure plates on the goujons.

Metal door blocks usually come with a seal, trim and fittings. The products are installed at the entrance to the building or individual offices of the organization.

Options for connecting structural elements

The main difficulty in assembling door frames is the process of connecting individual elements. The joining of horizontal and vertical strips of the product can be done in two ways:

I washed it down at an angle of 45 degrees. This process is best done with a miter saw, but in the absence of one, a miter box will do.
At a right angle of 90 degrees. To cut the workpiece you will need a saw with fine teeth.

The joining of the planks is carried out using tenon joints or galvanized self-tapping screws. The figure shows options for tenon joints, which clearly show how to assemble the door frame yourself to ensure high strength of the joints.

When calculating the parameters of the length and width of the profile slats, it is necessary to take into account that the length of the tenon should be equal to the thickness of the box beam. The tenon joint provides sufficient strength to the finished structure, but if desired, additional reinforcement of the joints can be made with zinc-coated nails.

How many components are needed for the opening?

When installing the door block, you will definitely need components. The aluminum door frame goes on sale with mounting plates, a seal, and a set of corners.

When purchasing a door frame for an interior door, a design is selected taking into account the installation location. Frames with a threshold are placed in the bathroom, at the entrance, or, if the height of the opening requires (3 blanks are required for one door). The U-shaped box is mounted in ordinary interior partitions (for one door you need 2.5 pieces).

The number of platbands is calculated according to the need for framing. On one side you need two and a half strips 2 m long. To cover both sides, buy 5 platbands.

If the door frame is narrow, the projections of a thick wall are hidden with extensions. The number of boards is calculated based on the size of the protrusion.

You will need hinges from the fittings. For a light sash, 2 elements are enough, and for a heavy sash you can put 3 pieces. Overhead or hidden hinges are placed on the door frame without a quarter. By design they are one-piece.

A lock and a peephole are installed on the front door. Although, the last element is optional. Any door is equipped with two handles, and a latch is attached to the interior door leaf.

Installation

Do-it-yourself installation is carried out in two stages. The first is assembly. Assembly must be done on a flat, horizontal surface, such as the floor.

It is necessary to connect all the parts together and adjust them to the dimensions of the canvas. If everything matches, proceed with installation.

Installation is carried out in the following queue:

Measurements are taken from the door and the locations for the hinges are determined.
A small layer of wood is removed so that the canopies lie in line with the stand.
Mount all parts.
Install the box in the opening.
Adjusting the position of the slats and checking the level of the built-in box.
Fixing the box with wedges.
Fastening the box with bolts.
Install spacers between the frame and the opening.
Filling the void from the box to the opening with polyurethane foam.
Removing protruding wedges and dried foam.

If all the conditions for manufacturing and assembly are met, then this operation will not be difficult for you.

Installation of the door frame can be done in different ways.

Internal method. It is based on fastening the box in several places: in the hinges, under the lock plate and in the wall. In these places, the box is secured with self-tapping screws, after which spacers are installed, and the resulting space is filled with polyurethane foam. This method provides a strong and durable fastening, but requires extreme accuracy in calculations and adjustment of the door, because after the foam has hardened, it will no longer be possible to adjust the door.

Bolt-on mounting. Reliable and time-tested mounting option.

Holes are drilled in the box.
The box is applied to the opening and the places where it is necessary to make holes in the wall are indicated.
The box is attached to the opening.
The bolts are decorated with plugs.

Mounting on hangers. Suspensions are plates attached to the box. After they are secured, the box is placed in the doorway, leveled and secured with bolts in the hangers. This method is applicable only before the finishing of the room, since the hangings on the wall must be hidden with plaster.

Expert tips and advice

Boxes are made of wood, fiberboard or MDF. Each material has pros and cons. When installing fiberboard boxes, the structure will bend from the weight of the panels, so it is not recommended to install such boxes. It is better to take wood or MDF.

The tree lasts a long time and looks beautiful. Any rocks are suitable for slopes. But more often they install MDF with PVC film. Designs with laminated film are not expensive, but require careful handling with sharp objects. If the film is scratched, it cannot be restored. Some people remove the protective film after installing the panels in the opening to minimize damage.

During major renovations, openings must be measured after finishing the walls and laying the flooring. During the process, the floor level and the width of the walls may change, which will lead to a large change in size. If there are wires in the trim, then calculate the optimal removal so that they spoil the appearance.

It is important to take into account the opening side of the doors, because the frame can be ordered with holes made for the hinges. And if the side is left instead of right, you will have to buy new elements. To determine the side of the door, look at which hand the leaf is on when opening. If the handle is on the left, and the door opens completely to the right, then the door is right-handed; and if it’s the other way around, it’s left. You can also identify it by the hinges, the left hinges are on the left door; and the right hinges are on the right door. For European doors, the concept of left and right is exactly the opposite. What is left for a European is right for us.

How to choose an interior door

Be careful, the doors are opening. And now they are closing. And now we clap them. Interior doors bear daily stress. Therefore, it is very important to choose high-quality door leaf and components.

Which room are we choosing a door for? Here's the first question you should answer before heading to the store. The width and height of the canvas, the dimensions of the box and the presence/absence of glazing will depend on the answers.

Door sizes for different rooms

Living room door

The standard door width is 80 cm. This size allows you to bring in/take out furniture without any problems. A width of 90 cm is rare; such canvases turn out to be heavy, and over time they can begin to sag in the loops. The most common canvas height is 190-200 cm.

Bathroom door

Bathroom doors are usually made 60 to 70 cm wide so that a washing machine can pass through the opening. The standard width of washing machines is exactly 60 cm. Keep in mind: an assembled door exactly 60 cm wide will have an opening of about 58 cm due to the rebates in the door frame. In order for the machine to fit through the door, it is worth taking a canvas wider than 60 cm. Most often, doors with a height of 190 cm are installed in bathrooms and toilets.
