The Knauf P 112 complete system is a complete set of specially selected materials needed to create a false ceiling on a two-level metal frame. The finished ceiling structure is not a structural (bearing) element of the building.

The main building elements of the ceiling:

• plasterboard KNAUF sheet;
• metal KNAUF ceiling profiles PP 60×27.

The complete composition of the complete system and the required amount of materials per 1 sq. ceiling meter, see “Technical data”.

Distinctive features of this system: the main profiles of the suspended ceiling frame, fixed using suspensions to the base ceiling, and the supporting profiles to which the Knauf plasterboard is attached, are located at different levels.

In addition to the main elements, the complete system includes the technical solutions necessary for solving a specific construction task, recommendations for the performance of work, as well as tools and fixtures.

All elements of the P 112 complete system are manufactured using modern technologies, undergo strict quality control, are functionally oriented and, as part of the complete system, ensure the reliability of the entire structure during long-term operation.

Suspended ceiling made of Knauf sheets on a two-level metal frame.

• The weight of one square meter of the ceiling is about 13 kg;
• the maximum distance between the fixing points of the frame to the base ceiling is 1200 mm;
• the maximum distance between the axes of the bearing profiles is 500 mm;
• the maximum distance between the axes of the main profiles is 1200 mm;
• the distance between the wall and the axis of the extreme main profile is ~100 mm.

The composition of the complete system – quantity per m² :

1. Knauf sheet (GSP-A, GSP-H2, GSP-DF) 12.5 mm – 1.0 m²
2. Knauf-profile PP 60×27 – 3.2 rm. m;
3. Profile extension – 0.6 pcs.;
4. Two-level connector – 2.3 pcs.;
5. Suspension with clamp and rod (Suspension straight, Nonius-suspension assembly) – 1.3 pcs.;
6. Screw TN 25 – 17 pcs.;
7. Anchor element – 1.3 pcs.;
8. Reinforcing tape – 1.2 rm. m;
9. KNAUF-Fugen putty – 0.4 kg;
10. Primer Knauf-Tifengrund – 0.1 l;
11. Separating tape – * rm. m;
12. Screw LN 9 -2.6 pcs.

* Quantity corresponds to the perimeter of the room.

** Position not shown in figure, used with direct suspension.

The data on the amount of materials are indicative, do not take into account cutting losses and require clarification on the project.

Application

Application area

It is used in premises for various purposes, both during reconstruction and in new construction in order to:

• finishes;
• solving structural and planning problems;
• elimination of irregularities in the overlap;
• hidden placement of engineering communications;
• increase the sound insulation of floors;
• acoustics;
• increasing the fire resistance of ceilings and coatings.

Mounting process

The installation process includes the following stages of work:

• marking the design position of the suspended ceiling frame;
• assembly and fastening of the frame;
• installation of KNAUF plasterboard sheets (GKL) in the design position and fastening to the frame;
• sealing joints between Knauf plasterboard sheets and, if necessary, continuous puttying of the suspended ceiling surface;
• priming the suspended ceiling surface before applying paint or decorative coating.

Recommendations

Installation of suspended ceilings should be carried out during the period of finishing work (in winter with heating connected), before the installation of clean floors, when all the “wet” processes are completed and wiring of electrical and plumbing systems has been completed, in dry and normal humidity conditions in accordance with SP 50.13330.2012 Thermal protection of buildings. Updated edition of SNiP 23-02-2003. In this case, the temperature in the room should not be lower than 10°C.

In conditions of high humidity (bathrooms, kitchens), it is recommended to use moisture-resistant KNAUF plasterboard sheets (GKLV).

The location of electrical wiring in the space of the ceiling frame should exclude the possibility of damage to them by the sharp edges of the frame elements or screws during the fastening of drywall sheets.

Painting suspended ceilings P 112 is recommended to be done with water-dispersion paints. It is not allowed to apply lime paints and paints on liquid glass.
