super-insulation definition

super-insulation required in Passive House means thicker assemblies at the walls, ceilings and floors. Maintaining a continuous, uninterrupted layer of insulation is important. When the building design includes overhangs, step-backs, or other envelope protrusions, additional insulation is needed not only at the uppermost roof and lowest floor, but at every panel of roof, wall, and floor created by corrugations in the building envelope. These assemblies can be many inches thicker than conventional assemblies, thus necessitating extra building space.
