Comparison with masonry
Approximate cost of your house walls with A++ insulation: ICF vs aerated concrete (AAC) with EPS.
| ICF | Masonry (built by a crew) | |
|---|---|---|
| Walls with A++ insulation | {{ formatEurRange(comparison.icf) }} | {{ formatEurRange(comparison.masonry) }} |
| Of which labour | €0 (you build it yourself) {{ formatEurRange(comparison.labour) }} | included |
| Extra living space | +{{ formatArea(comparison.extraArea) }} | – |
| Construction stages | 3 | 5 |
Counting the extra living space (~€1,000/m²), ICF works out better for you by about {{ formatEur(comparison.benefit) }}.
Counting the extra living space (~€1,000/m²), ICF and masonry would cost you about the same, but with ICF you build in 3 stages instead of 5.
Even counting the extra living space, ICF would cost you about {{ formatEur(-comparison.benefit) }}
more. In return, you get 3 construction stages instead of 5 and a single crew.
* Approximate, based on 2026 market rates, incl. VAT. Concrete, rebar and labour are calculated from the wall area minus openings. Masonry: 25 cm aerated concrete, 25–30 cm EPS, lintels, ring beam and labour. Façade reinforcement and finishing are not included.
