The current practice is that the deformations of timber façade elements are determined by testing, or they are limited by prescribing dimensions in a very conservative way. To use generic calculation models, suitable for almost all types of windows, approximations deviating from the actual behaviour have to be done. This paper investigates if a calculation method can predict the results from laboratory test with the required accuracy. For that purpose 29 façade elements were tested. Results showed that the calculation method gives a good, slightly conservative prediction for the laboratory tests. As a result, especially for specific project-made windows in small series, the costly laboratory tests can be replaced by calculation.     «
