Energy+ Wall System
About this product
Energy+ Wall System is the entry high-performance Passive House Block wall option. It keeps the exterior insulation layer outside the structural concrete core and gives projects a clear upgrade path from minimum-code wall thinking toward lower heat loss.
What is included in the wall logic?
- NEOPOR exterior insulation layer sized at 150 mm.
- Reinforced concrete core designed by the project engineer.
- Interior side finished with the selected Passive House Block panel/formwork strategy.
- Airtight monolithic wall logic with insulation placed outside the thermal mass.
Performance position
Indicative insulation-layer values are RSI 4.69, R 26.6 and U-value 0.213 W/m2K. This positions the option as an above-code / high-performance wall system before the full wall build-up is verified.
Best fit
- Projects that need a strong thermal upgrade without moving to the thickest wall option.
- Milder climates, budget-sensitive high-performance houses, or early-stage feasibility comparisons.
- Design teams comparing UK Part L, German GEG, EU/Croatia nZEB and US IECC R-value language.
Verification note
Final wall U-value must be calculated for the complete assembly according to EN ISO / HRN EN ISO 6946, including concrete core, finishes, geometry, junctions and thermal bridges.
Need calculations for your wall package?
Send drawings, target U-value, climate zone and planned wall build-up. We will help check insulation thickness, block type and core assumptions before the project moves into detailing.
