Building in cold climate zones requires a high insulation thickness and a good protection against interstitional condensation. Applying vapour tight membranes on both sides of a roof construction...
Design of mineral fibre durability test based on hygrothermal loads in flat roofs (2008)
Zirkelbach, D., Künzel, H.M., Bludau, C.
The durability of mineral fiber insulations depends to a large extent on coinciding temperature and humidity conditions within these materials. Existing test procedures use combinations of rather...
Condensation problems in cool roofs (2008)
Bludau, C., Zirkelbach, D., Künzel, H.M.
In some regions of the United States so called cool roofs have become mandatory in order to save cooling energy in summer and it is expected that these roofs will also become more widespread in other...
Begrünte Holzdächer ohne Dampfbremse (2008)
Zirkelbach, D., Künzel, H.M., Bludau, C.
Flachdächer mit Begrünung werden in der Regel auf der Außenseite mit relativ diffusionsdichten Bahnen ausgeführt, um ein Eindringen von Feuchte aus der Substratschicht in die Konstruktion zu...
Feuchteverhalten von Kellerwänden mit Innendämmung (2008)
Künzel, H.M., Zirkelbach, D., Bludau, C.
Die Innendämmung von Außenwänden erfordert in der Regel eine detaillierte Planung, um Feuchteproblemen z.B. im Bereich von Wärmebrücken oder durch Frost bei zu hohen Dämmschichtdicken...
Surface temperatures on flat roofs and hygrothermal consequences (2008)
Bludau, C., Zirkelbach, D., Künzel, H.M.
In this paper the temperature conditions on flat roofs are discussed considering the influence of long-wave radiation to the sky and the effect of a parapet as an important factor for the nighttime...
Zirkelbach, D., Künzel, H.M., Bludau, C.
Flat roofs with dark membranes experience higher thermal loads than most other building components. To increase also the moisture loads in the roof two litres of water per m² were inserted to a test...
