En jämförelse mellan vakuumisolering och traditionell isolering


The purpose of this thesis is to investigate if vacuum insulation panels are a competitive alternative to traditional insulation.Vacuum insulation has been used as insulation in buildings in Germany and Switzerland for a few years. In Sweden the high-performance insulation material is mainly used in refrigerators, freezers and vacuum thermoses. The development is proceeding well and vacuum insulation is becoming more common in the construction industry. Since it is a relatively unexplored material on the market there are many flaws and problems with the material.The questions we have chosen to answer in this report include an increased knowledge of vacuum insulation, various problems that may arise when handling/installation and the pros and cons of vacuum insulation compared to standard traditional insulation.The methods we have chosen to use in this report is a literature study, interviews with various suppliers and manufactures and calculations to show the differences between traditional and vacuum insulation. Vacuum insulation is 5-10 times better insulation than standard traditional mineral wool insulation, mainly at the beginning of its lifetime.Vacuum insulation panels (VIP) have a service life of approximately 50 years, whereas traditional insulation has a service life of approximately 100 years. In limited and confined spaces, the vacuum insulation is used as additional insulation. The insulation is also used to construct the "slim" and well insulated walls that are more aesthetically pleasing than half a meter thick wall of energy efficient buildings.There are several advantages of the vacuum insulation. Efficiency and energy savings due to its low U-value are the most important. The disadvantages are the expensive investment, the fragile metal case that is highly sensitive to mechanical damage and a shorter service life compared to traditional insulation.
