One can find numerous wooden panels on the market, which are used for furniture and construction purposes. Most often these materials are used over a long period of time which is why it is important to know the materials' behaviour at longer time loads, where the behaviour depends on the type or the material of the plates, the type and proportion of the glue, density, as well as the force with which the material is loaded. We determined the impact of the various types of wooden panels and their structures on the time load - creep. We used 3 different wooden panels: chipboard, fibreboard and construction panel. Panels were loaded on 4 points with an experimental device for determining the time of deformation. The time frame of the deformation was measured both at the bottom and the top side. Deformation was the smallest on the construction panel. The deformation of chip and fibre boards was higher, but the differences between them were smaller. We also found differences between the top and bottom side.
