Protection against moisture

The influence of humidity and has always been a problem of building and use of buildings. Building structures must be located, designed, and be fit for that caused by water and moisture is no danger or undue harassment. In conjunction with heaters today good hygienic living conditions are reached. Protection against moisture and heat protection cannot be considered independently. Inadequate protection against moisture reduces the insulation and poor heat protection can lead to moisture damage.

First Requirements:

The building heat and moisture protection must meet several tasks. To ensure hygienic living conditions, a minimum thermal insulation, sealing the building against moisture and a minimum air exchange must be ensured. For the well-being and performance of the residents, a comfortable interior climate can be achieved. With regard to the sparing use of resources to plan buildings are energy efficient to run and to use or operate. This concerns mainly the heating and heating energy consumption, but increasingly also other building equipment for cooling, ventilation, lighting, etc.

Second "Breathing Walls", sorption, diffusion:

A breathing space-enclosing the components in terms of air exchange between the room and outside air will not occur. Such behaviour of the components would also be undesirable, as this would occur, an uncontrolled heat loss and the airborne sound insulation would be insufficient. Porous materials will require vapour-permeable cross-section of multilayer structures of special constructive measures to prevent condensation of moisture and precipitation, and components to enable a hygienically acceptable occupancy.
