In this thesis we are dealing with the behavior of vacuum insulation panels (VIP) in terms of their properties and the possibility of their use in different construction assemblies. Their properties were analyzed using 2D thermal analysis in Therm. The first part deals with the general properties of the VIP. We have found out that effective thermal conductivity depends to a large extent on the size and shape of the VIP, the foil used, and the core material. Attention should also be paid to the lifespan. Time characteristics are influenced primarily by the change in internal pressure and the moistening of the core. VIP with SiO2 core are better suited for buildings, because of a longer life spain. They are more resistant to moistening, while the change in internal pressure affects them much less than when using glass cores. To ensure durability, it is necessary to use quality wrap foil. With foils that make it possible to achieve better durability, we usually cause a larger thermal bridge on the edge of the VIP and consequently cause an increase in effective thermal conductivity, so we have to be careful when choosing the foil. With simulating different construction sets, we found out that with the help of VIP we can produce relatively thin insulation layers that have better properties compared to traditional thermal insulation. We also concluded that their use is not impossible even in smaller dimensions, but the effective thermal conductivity due to the thermal bridge is somewhat reduced.
