Der neue DIN-Fachbericht 4108-8 Vermeidung von Schimmelwachstum in Wohngebäuden

Avoiding mould growth in dwellings — the new report on DIN 4108-8.

Problems with mould growth in residential buildings are an increasing occurrence. The construction of a dwelling house should ensure that, provided rooms are used in accordance with the design purpose, the internal surfaces of the building components stay sufficiently warm and dry so that mould growth is avoid ed. Where this is not the case, remedial measures have to be undertaken, such as installing additional insulation and/or ventilation/ heating devices. But it is equally important that the behaviour of the users of a building is appropriate for the design of the building. This includes evenly distributed space heating, adequate ventilation, air circulation that is largely unobstructed by furniture, and that moisture release in the dwelling is not excessive. The report on DIN 4108-8 'Thermal insulation and conserving energy in buildings — Part 8: Avoiding mould growth in dwellings' takes a comprehensive look at all relevant factors, such as construction details, heating and ventilation systems, and user behaviour. The report helps to clarify the causes of problems and makes suggestions for remedial actions.
