Strength comparison of joints at window frames

The strength of joints with a wooden ring, which are protected by international patent was compared with the strength of tenon dowel joints, and consequently the applicability and suitability for producing such window frames was established. The strength of different implementations of angular joints of window profiles was tested on a tensile-testing machine. It was established that the average ultimate strength of joints with a wooden ring was higher than the ultimate strength of tenon joints, which was chosen as an upper reference limit.
