Door openings

pcs

Each opening adds reinforced studs at the sides and a header.

Stud / profile spacing

600 mm — standard; 400 mm — under tile and heavier loads.

Room

We suggest the board type: dry → standard, wet → green, near fire → pink.

Sheet thickness

Reserve

How much material to take beyond the calculation for trimming and defects. Usually 5–15%.

Finish

“Joints only” — under wallpaper and tile; “full” — under paint (primer + finish).

Sound insulation

Mineral wool inside the frame damps sound through the partition.

Sheets needed

10sheets

Profile: 36 + 10.9 running m

Frame: 12 studs × 3 m

Recommendation

Board: Standard drywall

Standard drywall suits dry living spaces.

How the figure is calculatedPartition 5 × 3 m. Studs at 0.6 m → 12 pcs. Sheathing 13 m² × 2 sides = 26 m² of drywall + 15% = 10 sheets.

Profile and fasteners follow KNAUF norms, approximate. Place studs at 600 mm where sheets meet (400 mm under tile). For a partition, add sound insulation inside the cavity.

Calculation

Partition 5 × 3 m. Studs at 0.6 m → 12 pcs. Sheathing 13 m² × 2 sides = 26 m² of drywall + 15% = 10 sheets.

The calculation is approximate. Verify consumption against the specific material manufacturer instructions.
