Effective coverage per roll9.6 m²
Area with waste26.4 m²
Whole quantities are rounded up.
How it's calculated
Effective roll area = (roll width − side overlap) × roll length. Rolls = area with waste ÷ effective coverage, rounded up.
Calculations use consistent units for your selected measurements. The waste allowance is applied once to the measured requirement. Whole purchase quantities are rounded up.
What this estimate includes
Use zero overlap for butt-jointed insulation. Set overlaps only when the product installation requires them.
Quantity and arithmetic estimates only. Use project specifications for installation and design requirements.
