Reflection Compare the advantages and disadvantages of internal insulation. Feedback Advantages: listed buildings can be insulated without changing the façade. Disadvantages: more difficult in terms of the physics of buildings; risk of moisture and mould developing; usually less insulation effect due to limited insulation thickness; reduction in living space; thermal bridging through intersecting construction elements; higher costs in more complicated cases.
Multiple-Choice Question How can you minimize thermal bridging at the internal insulation? Answers Option 1 By using insulation wedges. Option 2 With an airtight layer. Feedback Right. Insulation wedges lengthen the path of heat flow at the intersection of internal insulation and intersecting elements, e.g. inner walls. Wrong. Thermal bridges must be dealt with independently of airtightness. Solution Correct Option (Feedback) Wrong (Feedback)
