Sheet Metal and Insulation Calculator
Calculates the weight of a sheet, the length of a coil, and the insulation sheet area (m²) needed to cover pipes.
Pack m² fills in automatically when you pick a thickness.
The cut width is the width of the sheet strip that wraps the pipe. Measuring with a strip of the same thickness around the pipe gives π × (diameter + thickness), which is the most accurate result in practice. m² = cut width (m) × pipe length (m). A waste allowance is added to the total. The pack count is the total area divided by the pack m², rounded up; how the strips are laid out on the sheet and the losses at elbows, valves and flanges must be assessed separately.
