The standard applies to frames, windows and doors in facade openings, made of unplasticized PVC profiles in accordance with NEN 7034, including the mounting and connection systems in the version as they are ultimately used in construction. Explanation This standard must be used together with the standards for the materials to be used. For example, no requirements are set for the maximum allowable vertical deflection of intermediate sills above which there are (glass) panels; in this case, the functional requirements of NEN 3576 must be met after installation.
