Better and cheaper extra insulation

In the current energy plan, focus in placed on further savings of heat in buildings. If the target of the energy plan should be achieved, there is a need for saving heat both in new and existing buildings.The article investigate and compare the properties of several systems for external insulation of buildings. The thermal performance of the systems is compared to an ideal situation, showing that there is still a potential of further savings by improving the design of the insulation systems.To improve the thermal performance of the systems a number of product developments are proposed.
