Indicative calculation

How many packs?

Packs from our own packing lists: area ÷ m² per pack, rounded up. With a target U-value the calculator shows the indicative insulation thickness d = λ × R.

Enter the area to see the number of packs.

Indicative only — the final choice and thickness are confirmed by your designer or Austrotherm technical support. The thickness estimate takes the insulation layer alone (R = 1/U) and does not check any regulation.
