How to use it

  1. Calculate area: 10m × 2.6m = 26m²
  2. Calculate placas (doble): 26m² × 2 caras ÷ 2.88m² × 1.1 (waste) = 20 placas
  3. Calculate perfiles canal (floor/techo): 10m × 2 × 1.1 = 22 units
  4. Calculate montantes (each 0.60m): (10m ÷ 0.60m + 1) × 2 = 34 montantes
  5. Calculate tornillos: 26m² × 20 ud/m² = 520 tornillos

Common mistakes

  • ⚠️ Not Use doble placa when requires insulation acústico
  • ⚠️ Separar demasiado The montantes (maximum 0.60m)
  • ⚠️ Not colocar lana mineral when The partition separa ambientes ruidosos

Worked example

Calculate materials to a partition of drywall of 10m × 2.6m with doble placa and insulation of lana mineral.

Tabique of {area_m2} m² requires {placas_ud} placas of plaster, {perfiles_canal} perfiles of canal, {perfiles_montante} montantes, {tornillos_ud} tornillos, {pasta_juntas_kg} kg of pasta and {lana_mineral_m2} m² of insulation.
