Varmeisolasjonsmaterialer for bygninger

The course Thermal Building Insulation Materials addresses traditional, state-of-the-art and possible future thermal building insulation materials, with respect to properties, requirements and possibilities. Basic thermal transport properties are treated, including solid state, gas, radiation and convection conductance. The advantages and disadvantages of the miscellaneous building insulation materials and solutions are discussed. Examples of insulation materials are mineral wool, expanded polystyrene, extruded polystyrene, polyurethane, vacuum insulation panels, gas insulation panels, aerogels, and future possibilities like vacuum insulation materials, nano insulation materials and dynamic insulation materials. Various properties, requirements and possibilities are compared and studied. Among these are thermal conductivity, perforation vulnerability, building site adaptability and cuttability, mechanical strength, fire protection, fume emission during fire, robustness, climate ageing durability, resistance towards freezing/thawing cycles, water resistance, costs and environmental impact. Currently, there exist no single insulation material or solution capable of fulfilling all the requirements with respect to the most crucial properties. That is, for the buildings of today and the near future, several insulation materials and solutions are used and will have to be used depending on the exact circumstances and specifications. As of today, new materials and solutions like e.g. vacuum insulation panels are emerging, but only slowly introduced in the building sector partly due to their short track record. Therefore it will be of major importance to know the limitations and possibilities of all the insulation materials and solutions, i.e. their advantages and disadvantages. In this respect new conceptual thermal building insulation materials are being explored, also including experimental investigations.

Knowledge, skills and general competence: Obtain an overview and deeper insight about the properties, requirements and possibilities, including advantages and disadvantages, about: - Traditional thermal building insulation materials. - State-of-the-art thermal building insulation materials. - Possible future thermal building insulation materials like e.g. nano insulation materials (NIM) and dynamic insulation materials (DIM). Obtain an overview and deeper insight about various thermal transport mechanisms, i.e.: - Solid state thermal transport. - Gas thermal transport. - Radiation thermal transport. - Convection thermal transport. - Leakage thermal transport. - Solid state and gas thermal transport interactions. - Thermal transport term accounting for second order effects between the various thermal conductivities given above. Investigate, discuss and explore the possibilties of inventing and making novel high performance thermal building insulation materials.

The tuition in the course Thermal Building Insulation Materials will be mainly based on a guided self-tuition. A few introductory and summary lectures/colloquiums will be given, though (also according to need). For å få bestått i emnet kreves det en score på minimum 70 prosent (70 av 100 poeng).
