For customers and planners of composite systems for thermal insulation, the quality of the product is not the only important thing because the expertise of the company responsible for the planning and technical installation of the product is also a decisive factor. The RAL Quality Mark for the Thermal Insulation of Façades using Composite Systems thus acts as a reliable guide because the award criteria place strict requirements on the expertise of personnel.

For example, the companies who are members of the RAL Quality Assurance Association for the Thermal Insulation of Façades must have at least one qualified manager with extensive knowledge and experience in the planning and execution of façade insulation projects. A manager in this sense means a master craftsman in the painting and varnishing trade or a master craftsman in the plaster-ing trade with at least 3 years of experience in the thermal insulation of façades. In addition, they must also have acquired the certificate “Energy consultant in the painting and varnishing trade or in the plastering trade” or a comparable certificate. Depending on the type and scope of the work, every building site must also have at least one trained, expert tradesman with a corresponding level of experience. To ensure that their personnel are kept fully up to date at all times, the holders of the quality mark are obligated to provide their employees with specialist training at least every 3 years. Therefore, the RAL Quality Mark does not only indicate that the employees have a funda-mental level of expertise and specialist knowledge but also that they receive the necessary educa-tion and training.
