About this product
NZEB+ Wall System is the 250 mm wall option for projects moving beyond ordinary nZEB thinking toward Passive House benchmark territory in cool-temperate climates.
What is included in the wall logic?
- 250 mm NEOPOR exterior insulation layer.
- Reinforced concrete thermal mass inside the insulated envelope.
- Selected interior face: gypsum board or removable OSB formwork depending on the block assembly.
- Wall strategy intended to lower heating and cooling demand before systems are selected.
Performance position
Indicative insulation-layer values are RSI 7.81, R 44.4 and U-value 0.128 W/m2K. This gives the option a clear high-performance position for Passive House-oriented feasibility work.
Best fit
- Cool-temperate climate designs where a lower wall U-value is a priority.
- Projects that need stronger thermal resilience and lower peak heat loss.
- Architects comparing Passive House Institute component criteria against national-code benchmarks.
Verification note
Final compliance cannot be assumed from insulation-layer values alone. The whole wall, openings, concrete core, finishes, junctions and thermal bridges need project-level verification.
Project calculation
