  • baffles with a wooden surface consists in the integration of doors and similar components. Due to the irregular component sizes, the actual elasticity of the finished cladding deviate significantly from the target values. The reason for this is that there are known baffle walls all assembly parameters due to the relatively large distances between the Elastic straps significantly affect the actual behavior when Absorption of impacts or blows on the surfaces of the baffle walls impact.
