External Wall Insulation System (EWIS)

Thermal insulation can lie behind a strong clinker wall or wood paneling, as so often with special facades. However, if the insulation is the outer shell of the building and is covered only with a thin plaster, it is called 'coating' (EWIS). These are defined here as the sixth group of wall types, and there are shown concepts for greening. If nothing fits, base planting and flower boxes are possible still, nevertheless, self climbing plants are to be avoided like ivy and wild wine.

EWIS can be 4 - 30 cms. Insulating material used are flaky to medium hard slabs or panels from mineral wool, styropor among other things, they are glued and/or drilled. 'To drill into' to the heat insulation, you do face some solutions. They minimize the intervention as well as the warm bridges and guarantee a weatherproof sealing. The growth systems are planned like with 'normal' walls and also can be mounted in the do-it-yourself construction.
