Moisture Behaviour of Hygroscopic and Non-Hygroscopic Insulation Material in Wood Framed Walls under the Influence of Natural Convection

Katrin Riesner, Georg-Wilhelm Mainka & Katrin Riesner
Energy saving requirements has lead towards highly insulated building components. The thickness of insulation in walls is for instance 200mm to 400mm in Central and Northern Europe. Thicker insulation may lead to an increase in the importance of natural convection on energy consumption and on vapour transport. Natural convection within thick wall insulation can cause a high moisture accumulation and a significant mould growth risk at the upper cold corner of the wall. Knowledge of...
