Interior doors serve to separate andsoundproofing of individual rooms. In fact, the problem of how to install an interior door yourself practically does not exist. It is solved very simply and quickly. The main thing is to decide on the choice of design and fit it into the overall interior of the house.
The concept of interior doors
It is designed to insulate rooms.from each other in one house (apartment). It does not have to meet high requirements for strength and locking capacity. Its role is more decorative than protective. Therefore, the design of such a door is lightweight.
"Pie" of an interior door.The design of interior doors includes a door frame, a door leaf, a threshold and fittings. The following main types of such doors are used: solid wood, paneled and panel doors, differing in the design of the door leaf. Solid wood has a door leaf made of solid wood or tightly assembled beams. A paneled leaf contains a frame, inserts (chipboard or MDF panels) and a sheet decorative coating (veneer, plastic, etc.). A panel leaf is made solid or hollow and consists of a frame, filler and outer coating. In solid structures, the filler is made of chipboard. In a hollow leaf, a filler in the form of empty cells (honeycombs) is used, and the outer coating is made of MDF (fiberboard). Partial glazing is sometimes used in paneled doors. Glass can be of different sizes and types (frosted, colored, corrugated, etc.). The door frame acts as a power frame, into which the door leaf is fixed through hinges. It is made of three strong wooden beams (two vertical and one horizontal at the top). The dimensions of the frame are selected according to the doorway in the wall. The fittings that come with an interior door include hinge elements, locking elements and handles. Return to contents</a>
Step-by-step instruction: preparation for installing the door
Installation of panel and panel doors.An interior door should be installed when the main construction (repair) work of the premises up to the final finishing is completed. The walls of the room should already be plastered and filled. The main thing is that the work associated with high humidity is finished, and the damp elements are dried. The presence of high humidity can adversely affect the wooden parts of the door. In order to avoid discrepancies in the size of the door in height, the thickness of the flooring of the room must be fully formed. Otherwise, it is difficult to finally plan the threshold of the door (the bottom of the frame). Preparation of the doorway in the wall is important. It is necessary to check the verticality of the walls of the opening - if the deviation is more than 1 cm, the required layer of cement mortar should be applied and the position of the wall should be corrected. The verticality should be checked with a plumb line. Local defects of the walls in the form of bulges should be removed with a chisel. The walls of the opening should be even, all small irregularities should be eliminated with putty. Only after all work with the doorway is completed can you measure the dimensions to select an interior door. The door size should be 2-3 cm smaller in all directions compared to the size of the opening. When selecting a door, you must take into account the thickness of the doorway. Return to contents</a>
Preparing the door for installation
Assembly diagram of an interior door.It is better to buy an interior door complete with a door frame. If only a door leaf is purchased, then you will have to make the door frame yourself. The frame is made from a box-shaped wooden beam with a specific profile. The required dimensions are determined by measuring the doorway. The door is prepared for installation in the doorway on the floor in a horizontal position. First, places for installing hinges are prepared. To do this, rectangular recesses for the hinge leaf are made on the side end of the door leaf, 20 cm from the top and bottom. The recess is made with a chisel. The hinge leaves are fixed to the leaf with screws. The leaf is placed in its place inside the door frame and the location of the opposite hinge leaves is marked on the vertical post of the frame. Using a chisel, recesses are made for the hinges in the marked places on the frame. The recess length should have a reserve of 10-15 mm compared to the length of the hinge leaf. Next, mark and install the locking fittings (usually a handle with a latch). At a height of 100-120 cm from the bottom on the opposite side of the door leaf from the hinges, mark the installation of the handle with a latch. A recess is cut out with a chisel from the end of the leaf for installing the locking mechanism. A hole for the handle is drilled in the leaf at the required distance. The handle with a latch is assembled and secured to the door leaf. The leaf is inserted into the frame, a socket for the latch tongue is marked on the frame post. Return to contents</a>
Door frame manufacturing
Marking the door frame for hinges.The door frame is made of three beams, which together form the letter "П". The side posts are usually connected at the top in one of two ways. The first method involves connecting the vertical beam to the upper horizontal beam at an angle of 45°. The beams are fastened with screws. To install them, holes are drilled perpendicular to the beam cut. The other connection option is the simplest. The horizontal beam is installed between the vertical beams perpendicular to them, so that its edge coincides with the ends of the posts. The beams are secured with screws from the side of the posts. Holes for the screws are pre-drilled in them. Return to Contents</a>

Installation of door leaf
Whether it was possible to do it on your own is determinedfinally by the quality of hanging the door leaf. To install an interior door - this means to ensure that the doors do not open or close by themselves, and that no force has to be applied when they are tightly closed. In this regard, it is necessary to approach hanging the door leaf responsibly. After fixing the door frame, the gaps between the leaf and the frame can only be adjusted using hinges. This important stage should begin with the preliminary installation of the leaf inside the door frame. Using various pads and spacers, the leaf is aligned relative to the frame. The gaps on the side and top should be minimal, but allow the leaf to enter the frame without load. If necessary, the increase in the gap can be reduced downwards, to the threshold. The door leaf wedged in this way indicates the final location of the hinges in the door frame post. The location of the hinges by height is precisely fixed and marked in the recess of the post. If necessary, it is noted that the recess depth must be reduced by means of an additional gasket. The final marking of the installation location of the handle lock plate in the door frame pillar is made. The door leaf is removed again. According to the specified markings, the hinges and the lock plate are fastened with screws in the frame pillars. The door is hung on the hinges. Return to the table of contents</a>
Additional operations
In order to finally , it is necessaryperform some additional operations. First, the gap between the frame and the wall must be filled with mounting foam. To do this, all door elements are covered with masking tape. The gap is treated with water from a spray bottle. Using a mounting gun, the gap is filled with mounting foam around the entire perimeter of the frame. After the foam has hardened, the excess is cut off with a knife. Wooden strips (casings) are attached to the ends of the door frame. The strips are joined together at the top at an angle of 45°. It is advisable to cover the surface of the frame in the places where the strip is attached with silicate glue. The casing is fixed with nails or screws with small heads. Carrying out all the operations allows you to install the interior door yourself. The tool needed to install the interior door:
