A 10% waste allowance was applied to the board count.
Thermal conductivity, adhesive coverage, and anchor density are estimates you supplied above — they are not derived from a cited standard, since they depend on the specific insulation and fixing products used. Adjust them to match your chosen system.
This is the thermal resistance of the insulation layer alone: R = 2.86 m²·K/W. It does not include the existing wall, adhesive, render, surface resistances, or thermal bridging, so it is not the assembly U-value. Do not compare it directly against a national insulation requirement — compare the full assembly's U-value instead.
Standard: ISO 6946
The anchor marks show a representative pattern (one near each corner, one centred), not a literal layout — the real per-board count and position depends on the specific ETICS system's technical approval (wind zone, building height, edge and corner zones), none of which this calculator models. Compare against "Anchors" above for the total quantity, not a count of the marks shown.
The layer section diagram is schematic: only the insulation layer is drawn to its real thickness. The wall, adhesive, mesh, and render layers are illustrative only — this calculator has no input for their thickness.
