The multilayer exterior insulation for building elements with ground contact reduces heat loss at the lower building closure. Three layers of Styrodur C can be used under base plates and two layers on basement walls. The overall thickness may be up to 300 mm in the case of load-bearing base plates and up to 400 mm in basement floors and walls. In this context, Styrodur C may be embedded up to 3.5 m into the groundwater.

Due to its technical properties, Styrodur C can be laid in multiple layers under the floor slab. The exterior insulation of the floor slab provides wall connections free of thermal bridges. Styrodur C can be laid in up to three layers. The total thickness of the thermal insulation layer is limited to 300 mm.

In the inverted roof, Styrodur C is installed above the sealing. This flat roof construction is made possible due to the very low water absorption capability of Styrodur C. Water-repellant and vapor-permeable separation layers are additionally used to prevent the accumulation of a permanent water film between the insulation boards. The double-layer installation of Styrodur C in an inverted roof now enables insulation material thicknesses of up to 400 mm.
