Calculators / envelope insulation

Envelope insulation.
Not attic-only.

Schedule insulation for a roof slope, ceiling, wall, floor or custom area. Vapour/air-control layers and lining are optional, while insulation can be purchased by packages, area or volume.

The import sets “roof slope” and transfers area only. It never chooses insulation thickness or layer build-up.
