Types of interior doors.The choice of ready-made doors is huge. They are made from different materials and have different designs. Usually, the question of how to install an interior door is solved quite quickly and easily. It is only necessary to take into account some nuances of installation and choose the right one.
Interior door: features of choice
When choosing an interior door, you should considerbasic requirements for them. Such doors should not protect from uninvited guests, that is, have increased strength and locking properties. Metal or heavy monolithic models are not used for such purposes. The main task of interior doors is to isolate interior spaces from each other. Since different rooms are in different conditions, the choice of door depends on their location. All interior doors must provide sound insulation, have a lightweight design and fit into the interior.
Interior doors can be either soliddesign, and with glass inserts. In addition, specific requirements are put forward to them: the door from the balcony (loggia) must have heat-insulating properties, and the bathroom door - a certain moisture resistance. Some options must be opaque, while others may have transparent elements. When choosing, it is necessary to take into account the installation conditions. The main installation parameters include the size of the doorway, the thickness of the interior partition (wall), the direction of opening of the door leaf. In addition, you should decide on the fittings: the handles should be comfortable, with a latching (locking) mechanism. Return to contents</a>
Interior Door Design
The choice of a door is largely determined by itsdesign. All types of interior doors structurally consist of a door frame, door leaf, fittings and threshold (may be included in the frame). The door is fastened through the frame, which serves as a frame. The frame is made of a wooden beam, fastened in a U-shape. The dimensions of the frame are selected strictly according to the dimensions of the doorway. The thickness of the frame must correspond to the thickness of the wall. Decorative trims are installed on both front sides of the frame. The main element that provides functional properties and appearance is the door leaf. Three types of door leaf are mainly used: solid wood, paneled and paneled. Solid wood is made of a monolithic sheet (wood, plastic, composite) or in the form of tightly combined beams. Paneled construction consists of a rectangular frame, inside which there are inserts (panels) made of chipboard or MDF.
Construction of interior door.The frame is covered with a decorative covering (plastic, veneer, etc.) in the form of a sheet. The panel door leaf consists of a wooden frame made of beams, a filler and an outer covering made of MDF (fiberboard) sheets. The filler can be made of solid chipboard boards or in the form of an openwork mesh of cells (honeycombs). The design of the interior door can include a glass element of any size and shape (rectangle, oval). The element itself can be transparent, matte, colored, with relief or in the form of stained glass. The set of mandatory fittings includes hinged elements for fixing the door leaf on the door frame, as well as handles for easy opening of the door. Doors can be equipped with locking fittings in the form of latches or locks. A combined handle-latch is usually used. Handles, together with their overlays, play a noticeable role in the entire external design of the door. In addition, if necessary, other decorative elements in the form of overlays, strips, etc. can be used. Return to contents</a>
Step-by-step instruction: preparatory work
The interior door should be installed onlyafter completion of repair or construction work before finishing the walls. Naturally, the wall where you should install interior doors yourself should be plastered and puttied, and well dried after these operations. Before installing an interior door, you need to complete the preparation of the doorway. First of all, check the verticality of the walls. If the deviation from the vertical is more than 1 cm, it is advisable to apply a layer of cement plaster and correct the situation. All bulges are removed with a chisel. Only after this are the final dimensions of the opening measured and the dimensions of the door frame specified. The dimensions of the frame should be 2-3 cm smaller than the dimensions of the opening. Return to contents</a>
Preparing the door frame
Sectional view of door frame installation.In order to install an interior door yourself, you must first prepare the door frame. The frame is assembled from a standard door beam selected according to the width of the wall. First, two vertical posts are cut to a length equal to the height of the doorway, minus the thickness of the threshold and the size of the gaps (approximately 15 mm), as well as the upper horizontal crossbar to a length equal to the width of the opening minus the size of the gaps (3-4 cm). The upper part of the posts and both ends of the crossbar are cut at an angle of 45 degrees. The posts and crossbar must fit precisely along the cuts. A through hole (through the post and crossbar) with a diameter of about 2.5-3 mm is drilled perpendicular to the cut at the joint. The frame parts are fastened together at the drilled hole with a long screw. There should be two such fasteners at each joint. It is recommended to place a thin sealant, such as cardboard, between the parts to be joined. Return to Contents</a>
Preparing for installation
Some conditions are recommended to show,how . First of all, the door is prepared for installation in a horizontal position on a flat surface. First, two rectangular recesses are made on the side end of the door leaf according to the size of the hinge leaf (top and bottom). The recesses are located at a distance of about 20 cm from the edge of the door leaf. A milling cutter or chisel is used for this. The corresponding hinges are fastened with screws in the recesses.

The fittings are assembled. Then the door leaf is installed in the frame as it will be located after the door is installed. The location of the mating parts of the hinge on the door frame post and the place where the latch tongue enters the opposite frame post are marked. The door leaf is removed. Notches are made on the frame posts for the hinge with a reserve of 10-15 mm along the length of the hinge to allow for adjustment during installation. A notch is made for installing the latch plate and fixing the tongue. Return to the table of contents</a>
Mounting the door frame
independently begins with securing the boxin the doorway. First of all, the threshold is installed and secured. It is made from a board 20-25 mm thick and the length is equal to the width of the doorway. The upper part of the board sides is rounded on both sides. The door frame is installed in the doorway and wedged using specially prepared wedges at the top and bottom. A temporary spacer is installed at the bottom of the frame, preventing the posts from shifting. The verticality of the posts and the horizontality of the lintel are checked with a level and a plumb line. Fastening holes are drilled in the frame posts at a distance of up to 30 cm from each other. Through these holes, holes are made in the concrete using a hammer drill or electric drill. Dowels are hammered in, and the frame is secured with screws. The gap between the wall of the opening and the frame is filled with polyurethane foam. The spacer is removed.

Suspension of the door leaf
Tools for door installation.Installing an interior door yourself means correctly hanging the door leaf so that it opens and closes without effort, but does not do so spontaneously. First, the door leaf is pre-installed in the frame, by laying thin plates, the same minimum gap is ensured between the leaf and the frame. The largest gap can only be at the bottom, at the threshold. This final location of the door leaf is fixed. The specified position of the hinges on the door frame rack is noted. The door leaf is removed from the frame again. The reverse parts of the hinges are fixed with screws on the frame rack according to the final marks. Only after this is the door leaf hung on the hinges. The quality of opening and closing the door is checked. Finally, all excess foam is cut off, the gap is finally smoothed out (filled with putty if necessary), and a casing is fixed to the frame, which is a wooden or plastic strip, which is cut at an angle of 45° at the joint. The casing is fastened with screws. All detected gaps and local defects are best filled and sanded immediately. The installation of all decorative elements confirms the fact that it was possible to .
