  4. 3. An evaluation of two well insulated roof structures

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Author : Filip Josefsson; Oskar Cederlund; [2015]
    Keywords : Mould models; WUFI; Hygrothermal; Attic; Cathedral roof; Moisture; Mould growth; Technology and Engineering;

    Abstract : Moisture is considered to be a severe problem in outdoor ventilated attics in Sweden today (2015), and almost 60% of all single family houses and 10% of all multifamily houses have problems with mould growth correlated to moisture in the attics. Increased insulation layers and new heating systems in combination with a more humid climate have increased the risk of such problems. READ MORE
