Abstract

Adding insulation material on ceilings against cold ventilated attics is one of the most straightforward tasks of adding insulation. Theoretically, a higher amount of insulation in the attic decreases the temperature and consequently the capability of removing infiltrated indoor humid air. Field measurements of the moisture balance in 20 cold ventilated attics with different amounts of insulation material were analysed. Results show that the amount of insulation material has no decisive effect on temperature in the attic during winter. The moisture level during winter was generally just below the threshold for mould growth.
