Insulation installed beneath the flooring is called underfloor insulation in NZ, and it is a form of protection that is common in New Zealand. Insulation of this kind is also called thermal insulation in some circles. In addition to the walls that separate the various floors, it is typical to find them installed in crawl spaces and basements. Depending on the type of material or technology that is used for insulating space, the installation process often does not take more than a day to complete and can cover areas of varying sizes. These efforts have the dual purpose of delivering benefits connected to thermal comfort while also minimizing costs linked to energy use.
