How to use it

  1. Calculate area: 10m × 3m = 30m²
  2. Apply waste: 30m² × 1.05 = 31.5m² of planchas
  3. Convert thickness: 6cm = 0.06m
  4. Calculate volume: 30m² × 0.06m = 1.8m³ of insulation

Common mistakes

  • ⚠️ Not Consider puentes térmicos in encuentros with forjados and columns
  • ⚠️ Use thickness insuficiente to The zone climática
  • ⚠️ Not prever barrera of vapor when The insulation va in cara interior

Worked example

Calculate insulation for 50m2 wall.

To {area_m2} m² of area need {plancha_m2} m² of planchas of insulation (with 5% of waste), equivalentes a {vol_m3} m³ of material.
