How to make drywall partitions


At the same time, there is a double benefit: saving money from not attracting builders and enjoying the work done independently. The simplest and best option would be to install drywall partitions.

Plasterboard partitions have many advantages, including:

  • short installation time;
  • small (no more than 50 kg / m2) weight;
  • obtaining immediately after installation of absolutely flat surfaces for finishing work;
  • good sound insulation;
  • fire resistance;
  • the possibility of installing communications in a hidden way.

Plasterboard works are carried out after the completion of construction work, during the period of finishing work, but before the installation of clean floors. During installation, the room temperature should not be less than +10? FROM.

Installation of plasterboard partitions is performed in a specific sequence:

  • markup is in progress;
  • drywall guide profiles are mounted;
  • drywall racks are mounted;
  • the first side of the partition is sheathed;
  • insulation is placed in the cavity of the plasterboard partition;
  • the second side of the partition is sheathed.

The markings of the partitions that need to be erected are performed on the floor, after which, using a plumb line, they are transferred to the ceiling and walls. Guide and post profiles adjacent to building structures are pasted over with sound-insulating elastic tape, or silicone sealant is applied to their surfaces adjacent to building structures.

Installation of metal profiles can be performed not only with a single or double frame, but also as a double frame with a space inside to ensure the laying of all kinds of communications. Partitions can also be made using a wooden frame, which is lined with drywall sheets.

Installation of partitions

The metal frame is assembled using guide profiles, for example, PN50, which must be fixed on the floor and on the ceiling, rack profiles are also used, for example, PS50. Guide profiles serve a double role: they serve as guides for the rack-mount profiles and are used for laying the lintels between them in the frame. PN – the profiles are mounted in a pair with the corresponding size PS – profiles.

The guide profiles, in accordance with the markings, are fixed on the ceiling and on the floor using dowels, hammered in at an interval of not more than 1 m, their number should not be less than 3. In the same way, the wall rack profiles are fixed. Rack profiles are cut according to the height of the room, making a tolerance downward to 1 cm. This is necessary to ensure that the frame deformation is independent of the floor deformation..

Following this, rack profiles with a step of 60 cm, counting from one wall, are installed in the guides at the top and bottom, fastened with screws or by cutting. You can overlap the rack profiles along the length. The length of the overlap is determined by the size of the profile and must be at least (in cm) than the size of the profiles, for example, for PS-50, the size of the overlap must be at least 50 cm. Riveted or self-tapping connections are made in the overlap areas.

Simultaneously with the installation of the frame, door frames are installed. For this, support post profiles are mounted on both sides of the door frame, which are reinforced, taking into account the weight of the door leaf. Reinforced support profiles are fixed with angle brackets to the ceiling and floor.

You can start sheathing the frame. To do this, cut drywall sheets along the height of the partition. This is done as follows: on a flat surface with a sharp knife or a special cutter, the outer cardboard layer is cut and the plaster core is cut, the cut line is placed on the edge of the table, the plaster core is broken and the cardboard layer on the back is cut. The resulting edge is processed with a plane. If, when finishing at the joints of the sheets, a reinforcing tape will be used, then a chamfer is removed at an angle of 45? 1/3 of the thickness of the sheet, when closing the seams without a reinforcing tape, the chamfer is removed by 2/3 of the thickness of the sheet at an angle of 22.5?.

Prepared drywall sheets are mounted on the frame

Prepared sheets of drywall are mounted on the frame. To do this, they are installed vertically so that the upper edges of the sheets fit snugly to the ceiling and are fixed with self-tapping screws. Fastening must start from the corner in two mutually directions, forming a right angle, the minimum distance of the self-tapping screw from the edge of the sheet is 1 cm for glued and 1.5 cm for non-glued edges, the installation step is not more than 25 cm. Self-tapping screws are twisted strictly perpendicular to the plane of the sheet. The length of the self-tapping screws should be such that, when completely twisted, they protrude from the inside of the profile beyond its limits by at least 1 cm. The heads of the self-tapping screws must be sunk into the thickness of the drywall sheet by 1 mm or more. The joints of plasterboard sheets must be located on the profiles. If necessary, jumpers are made from the PN profile between adjacent PS profiles. A gap of 1cm is required between drywall sheets and the floor.

If, after installation on one side of the profile of drywall sheets, the cavity of the partition is filled, if necessary, with heat or sound insulating material, for example, mineral wool, expanded polystyrene, then it must be securely fastened. This is done using the remnants of the profile or inserts made of drywall. Next, the drywall sheets are installed and fixed on the other side of the profile.


For cladding partitions that are installed in rooms where the humidity is high, it is necessary to use a moisture-resistant drywall. When using ordinary sheets of drywall and further tiling, those places where moisture can get on the drywall must be additionally covered with waterproofing.

If necessary, electrical cables can be passed through the holes in the walls of the profiles that form the racks, while they should be placed in plastic tubes perpendicular to the racks. Sockets and switches are installed in special junction boxes, and the wiring is done in junction boxes – everything for drywall. The junction boxes on either side of the partition must be spaced at least 1m offset. In places where partitions are crossed by heating or water supply pipelines, it is necessary to install sleeves.

After installing the sheets of drywall, they begin to putty the seams at the joints of the sheets and the heads of the screws. The partition is ready. Nothing complicated.
