Building a wall or ceiling in plasterboard takes more than the board. The board needs the right frame and its joints need to be finished with filler. Here are the main parts of the Nikan dry-wall system.
The board: three choices
Boards are 2400×1200 mm (2.88 m²) with an AK edge. Regular Gypsum Board 9.5 is the lightest in the range (6.3 kg/m²) and suits suspended ceilings and decorative work. Regular Gypsum Board 12.5 (8.2 kg/m²) is the main project board, for partitions and separating walls. For bathrooms, toilets and kitchens choose the green-faced Moisture-Resistant Board 12.5. Boarding a wall in two layers with mineral wool inside gives better sound insulation.
The metal frame
The drywall profiles include the U runner (4 m) and C stud (3 m) for walls, CD profiles for suspended ceilings, and UH profiles and L angles for edges and finishes. For walls up to 2.7 m use the 3 m C stud, and choose a runner and stud of the same width — for example U70 with C70.
A simple estimate
Sheets equal area divided by 2.88, plus waste. Studs equal wall length divided by 0.6, plus one (studs sit every 60 cm), and runners equal twice the length divided by 4. For a wall 10 m long and 2.7 m high, boarded on both sides, the area is 54 m²: 19 sheets, 18 studs and 5 runners before waste. The estimator on the board pages does this sum for you.
Finishing materials
Joint filler (20 kg bags) fills the joints, drywall accessories include the 3.5×25 mm board screw (12,000 per pack), and gypsum ceiling tiles are for modular ceilings. All can go on the same order as the boards.
If you would rather avoid wet plaster
The G-Wall gypsum block is a prefabricated wall unit of 66×50×8 cm that locks together and is bonded with a special gypsum-mortar adhesive. It suits internal non-load-bearing walls and needs about 3 blocks per square metre.
Sales are by the ton, and a sales specialist confirms the final estimate.
