A low µ value means that the insulation material is vapour-permeable, so that penetrating water can easily escape.

Insulation materials with a low vapour diffusion resistance factor (i.e. which are vapour-permeable) even indoor humidity out well.

Building materials with high specific heat capacity, which store heat well, even the temperature profile in buildings out. The reason for this is: the more heat a material can store, the less it is affected by cooling or by heating in summer, which in turn reduces the heat or cooling energy requirement.

If voids develop in the insulation layer, the insulation effect deteriorates.

Primary energy consumption is calculated from all forms of energy consumption needed to manufacture a product. Cumulated energy consumption (CEC), on the other hand, refers to the amount of energy that is needed to produce, transport, store, and dispose of an insulation material.

Feedback: this assignment has an open outcome.

Suggested answer: insulation materials made from renewable resources count as ecologically sound insulation materials. They include: wood fibre insulation panels, cellulose, flax, hemp, cork, sheep's wool and straw. Depending on requirements and the customer's budget, you can suggest insulation options with wood fibre insulation panels or cellulose, for example.
