Passive House Block zidni sustav za zgrade s malom potrošnjom energije

Passive House Block is a high-performance insulated wall system with 150 to 300 mm insulation options. The 300 mm configuration reaches an indicative U-value of 0.107 W/m2K and RSI 9.38 for the insulation layer. Final results depend on the full wall build-up, junctions, airtightness and project calculation.

Choose by climate, energy target, budget and wall strategy. Options are 150 mm Energy+, 200 mm NZEB, 250 mm NZEB+, and 300 mm Passive House Block for passive-house-oriented envelope targets.

Efficient equipment matters, but a weak envelope makes it work harder. First reduce demand with insulation, airtightness and thermal-bridge control; then heat pumps, solar and ventilation can run with smaller loads, lower costs and less stress.

Airtightness preserves real wall performance by limiting uncontrolled air leakage. It improves comfort, reduces heating and cooling demand, supports heat-recovery ventilation and lowers condensation risk inside the structure.

Passive House Block combines insulation with a monolithic concrete core in one wall system. The real comparison is the complete shell: structure, insulation, airtightness, facade strategy, weak-point control and long-term operation.
