Masonry — Materials
Record element dimensions, pieces per m², pack contents and the applicable density. A density alone does not determine thermal conductivity or structural suitability.
Masonry
- Aerated concrete
- ceramic block
- brick
- silicate
- concrete
Thermal conductivity, density and dimensions vary by product. Enter verified product data in the calculator.
Product documentation
Use the manufacturer’s declaration or technical sheet for the exact product and intended use. Record the source, thickness, thermal conductivity, density, coverage and units where relevant. A material family is not a certified design value. Use comparable conditions when comparing products.

These are hypothetical purchasing examples. Use the exact product, joint specification, pack contents and current supplier price for your order.
Inputs: 20 m² gross wall area, 2 m² openings, 12.5 pieces/m² and 5% allowance. Round required pieces and packs up to whole units (⌈x⌉).
20 − 2 = 18 m²; 18 × 12.5 × 1.05 = 236.25 → 237
| Stage | Option A | Option B |
|---|---|---|
| Net area [m²] | 18 | 18 |
| Required pieces | 236.25 → 237 | 236.25 → 237 |
| Pieces per pack | 60 | 50 |
| Whole packs | ⌈237 / 60⌉ = 4 | ⌈237 / 50⌉ = 5 |
| Purchased pieces | 4 × 60 = 240 | 5 × 50 = 250 |
| Surplus pieces | 240 − 237 = 3 | 250 − 237 = 13 |
| Cost [EUR] | 4 × 80 = 320 | 5 × 70 = 350 |
Both options cover 237 required pieces. At illustrative prices of EUR 80 per 60-piece pack and EUR 70 per 50-piece pack, A costs EUR 320 and B EUR 350, before delivery. A cheaper pack does not necessarily mean a cheaper order. Compare interchangeable products, identical tax treatment and delivery terms. Mortar, lintels, special pieces and structural suitability are separate checks.
