Formula and assumptions
How this calculation works.
Fit full pipe-wrap strips across a roll and pack measured continuous segment lengths along those strips. Strip width = π(pipe diameter + 2 × specified insulation thickness) + lap; lanes = floor(roll width / strip width).

Wrap rolls to purchase: 2 rolls
Continuous-piece packing uses decreasing-length first fit. It is feasible for the stated pieces but is not guaranteed optimal. No cut kerf, damage or end trim is assumed; include these in your supplied piece lengths. Wrap thickness and lap come from your supplied plan; thermal performance is not assessed.
Before you purchase
Use dimensions from your plan and properties from your chosen product. Any design spacing, section or fixing pattern must already be specified.
All product dimensions, coverage, density, allowances and joining rules must come from your supplied plan or selected product. No building-code values are inserted.
