Perimeter insulation panels made of Neopor® have good lambda values and therefore strong thermal insulation properties. In addition, they are stable under pressure at different installation depths and pressure loads, and are highly resistant to normal soil moisture. During installation, it is important to follow the specifications of the national technical approval for the relevant area of application. Neopor® insulation panels also provide the base of a building with effective protection against heat loss. Perimeter and base insulation panels do not assume functions such as providing drainage or sealing buildings against moisture.
