Diagram of the door from MDF.
Selection of interior products
First measure the length and width of the opening, lookthickness of the doorpost and then determine the dimensions of the interior design from the obtained data. It should be noted that the purchase of gates is required in the event that the opening or canth is a bit wider. Mounting foam is necessary to fill the voids. Usually the kit includes:
- door leaf;
- a box (bruski);
- accessories.
That the product has passed acclimatization, it is necessary to put it horizontally there, where it in the subsequent will be mounted.
Assembling the interior door
Marking of the door frame for the hinges. The door must be placed on the floor in a horizontal position, beforehand, covering the surface with a soft material, otherwise scratches remain on the canvas. Further, the bar is applied to the product so that the distance from them to the web is 3 mm. The bar from above is measured exactly with those that are located on the sides, and sawed at an angle of 90 °. After that, the height of the opening is measured, where the door is installed. The data is transferred to the construction (from the edge of the bar from the top to the bottom). The gap between the floor and the linen should be 2 cm. Then the bars are joined with the help of self-tapping screws, the length of which should be twice the width of the bar. To the door hinges are applied from above and from below at a distance of 20 cm. Their arrangement is indicated by a pencil. To deepen the details by means of the chisel, the contour is deepened along the thickness of the loop. Further fastenings fasten to a cloth self-tapes. The resulting design is inserted into the opening. When a large distance is left from the box to the joint, it is filled with foam.
Installation of the product
When the structure is in the opening before filling with foam, you need to check the plumbs with a level. 
Installation of the door frame in a section. The cloth is applied in the same way as a closed door, and 3 mm spacers are placed in intervals. Further, the geometry of the door is checked. It is important that the diagonals are equal and there are no distortions. The door frame is reinforced in the opening by a dowel-nail (two - top and three - on both sides). If the masonry is made of bricks, you need to make sure that the fastener is not in the gap between the bricks, otherwise it will loosen. After the design is installed, the hinges on the box are securely fixed with screws. When the remaining distance is filled with foam, you need to align the door horizontally. At the last stage, a cash register is installed, which is adjusted to the dimensions of the door, the handle is attached. When the installation of the interior door is finished, it is left closed for 24 hours and if possible do not use it. Independent installation of a door from MDF requires care and accuracy in the measurements, therefore, during installation it is necessary to check the dimensions several times. </ ul>
