This paper investigates the mechanical resistance of ETICS, with different types of thin-layer rendering, by means of hard body and point load impacts on such surfaces. Core materials, made of different thicknesses of EPS (expanded polystyrene) were also tested for their resilience to such loads, as well as the elasticity of widely-used applied rendering. Test results focused on the possible impact level on ETICS in use. The robustness of the output results and testing methodology can be replicated and used independently by any stakeholder in the construction industry. The aim of the research is to develop a reliable method to determine the elasticity of the rendering which can be used to predict the mechanical resistance of ETICS. This paper presents the results of a study on the influence of a particular component of ETICS systems on their overall impact resistance, based on standards and modified methods. A novel simplified device for testing the rendering bending angle was designed, constructed and tested. The device investigates the rendering elasticity of ETICS. Results indicated that,with an increasing angle of cracking,the more elastic coats crack less while being subjected to an applied point load.

本文通过硬质体和点载荷对此类表面的影响，研究了具有不同类型的薄层渲染的ETICS的机械阻力。还测试了由不同厚度的EPS（膨胀聚苯乙烯）制成的芯材对此类载荷的回弹力，以及广泛使用的应用抹灰的弹性。测试结果集中在使用中对ETICS可能产生的影响。建筑行业的任何利益相关者都可以复制和使用输出结果和测试方法的鲁棒性。该研究的目的是开发一种可靠的方法来确定抹灰的弹性，该方法可用于预测ETICS的机械阻力。本文介绍了基于标准和改进方法的ETICS系统特定组件对其整体抗冲击性的影响的研究结果。设计，构造和测试了一种新颖的用于测试渲染弯曲角度的简化设备。该设备研究ETICS的渲染弹性。结果表明，随着开裂角度的增加，弹性更大的涂层在承受点载荷时开裂更少。
