Superinsulation
![The passivhaus standard combines superinsulation with other techniques and technologies to achieve ultra-low energy use.](/Images/godic/202502/14/Passivhaus_section_en2053.jpg")
Superinsulation is an approach to building design, construction, and retrofitting that dramatically reduces heat loss (and gain) by using much higher levels of insulation and airtightness than normal. Superinsulation is one of the ancestors of the passive house approach.
