Wall Performance

Four insulation thicknesses position the system from above-code performance to Passive House-oriented cold-climate wall assemblies.

Build Logic

Straight, corner and interior wall variants share one assembly language across gypsum-board and removable OSB formwork options.

A compact product system where wall performance, geometry and detailing are designed together.

Select the insulation level first, then match it with the correct block form factor. The page keeps the engineering language visible without turning the catalogue into a spreadsheet.

Passive House Block products

Passive House Block wall systems are compared against international wall-performance benchmarks, including UK Part L, German GEG, EU/Croatia nZEB context, US IECC R-value language, and Passive House Institute component criteria.

Values are indicative and calculated for the insulation layer. Final wall U-value must be verified for the complete wall build-up according to EN ISO / HRN EN ISO 6946, including concrete core, finishes, geometry, junctions and thermal bridges.

FAQ

Frequently asked questions

What to know before choosing a block format or wall-system target.

How energy-efficient is the Passive House Block wall system?
Performance

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.

Which insulation thickness should I choose?
Thickness

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.

Why not just use a heat pump, solar panels and better HVAC?
Systems

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.

More Products
Why is airtightness so important?
Airtightness

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.

How is Passive House Block different from brick, gas block, SIP or frame construction?
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.
