Abstract

This contribution deals with the verification of airflow in the real air gap of an insulated roof deck with a pitched roof. The designed construction of the roof meets the thermal technical requirements for an energy passive house. The aim of this contribution is a comparison of experimentally measured values with values obtained through a computer simulation. Double skin ventilated roof structures operate on the principle of the removal of moisture vapour by the flow of air. The flow of air is generated by the difference in the density of the air gap. The air gap is created by the warming of the air from the interior, radiation from the night sky and the influence of the external flow of air. The most striking was the first factor, which is significantly reduced with increasing thicknesses of thermal insulation. This raises the issue whether the air flow in passive insulated roof cladding is sufficient for the removal of moisture from a construction, and how it affects the functioning thereof.
