Superinsulation is an approach to building design, construction, and retrofitting that dramatically reduces heat loss (and gain) by using much higher insulation levels and airtightness than average. Superinsulation is one of the ancestors of the passive house approach.

==Definition== There is no universally agreed definition of superinsulation, but superinsulated buildings typically include: Very high levels of insulation, typically R-40 (RSI-7) walls and R-60 (RSI-10.6) roof, corresponding to SI U-values of 0.15 and 0.1 W/(m2·K) respectively) Details to ensure insulation continuity where walls meet roofs, foundations, and other walls Airtight construction, especially around doors and windows, to prevent air infiltration pushing heat in or out Carefully managed air exchange, using a heat recovery ventilation system to provide fresh air rather than uncontrolled air leakage Window size and number minimized while meeting functional requirements; in particular, no large windows facing any particular direction Much smaller than a conventional heating system, sometimes just a small backup heater
