Isover EPS DD Universal drainage boards

Drainage boards are another type of insulating boards made in forms. They are designed in particular for use with basement walls in buildings or for the adjacent parts of the plinth. Drainage boards are also used in the construction of buildings where reliable drainage of the area, together with protection against frost, must be provided (support walls, foundations, etc.). In comparison with Perimetr standard boards, the drainage boards are completed with a special drainage raster which reliably ensures that water is led away to the drainage pipes from a large area. Like Perimetr boards, drainage boards do not require any damp-proofing insulation. The three main functions of Isover drainage boards are: the creation of the drainage of a large area; the protection of the damp-proof insulation (they replace a protective retention wall) and the thermal insulation in the lower part of the building (basement, foundations), and the removal of the usual thermal bridge.
