Advantages
faster, better, passivhaus certified

"one of the most comprehensive whole house certified building systems in the world"
- Passive House Institute, Darmstadt

Superstructures
passivhaus certified details for entire system
closed panel envelope (delivered to site ready to take plaster internally with electrical services factory installed)
fasted route to completion in a totally bespoke system
more robust than masonry (but allows for masonry outer leaf or cladding)


hybrid timber frame SIPS (structural insulated panel)
sustainable materials with a high recycled content
soundproof
breathing (vapour open from the VCL layer)
optimum thermal mass
low embodied carbon
optimised for integrated MVHR (mechanical ventilation & heat recovery)
adjustable u-values from <0.15 W/m2K
optimised for use with system insulated passivhaus foundation and basement (THEPASSIVHAUS Foundation System / THEPASSIVHAUS Foundation System ICF)


Substructures

passivhaus certified details for entire system
insulating permanent formwork pre-cut in the factory and assembled in a day on site (1 day/100m2)
costs the same or less than conventional foundations
much faster installation than conventional foundations
integral optional U/F heating
low or zero steel mesh or rebar - substituted for carbon fibre reinforced concrete premixed and pumped
minimal dig/spoil disposal
all ground types from <50kN/m2 including heaving clay


integral radon barrier/DPM
high thermal mass on correct side of insulation
thermal bridge free and U-Value 0.1 W/m2K or less
minimal RC (200mm typical) in a single pour
extended on no bay areas
exceptionally high line and point loading (>100kN)
allows complex slabs including multilevel and curved
finished floor power floated or polished surface without need for screed layer


a stable technology - based on over 50 years of industry use
optimised for use with Axios Trousse superstructures
