The renovation of buildings is usually characterized by great effort. The requirements are particularly high when it comes to publicly accessible buildings for which an upgrade in the sense of preventive structural fire protection is required. Fire protection coatings are between 0.4 mm and 3.5 mm, depending on the required fire resistance period, are statically hardly stressful and space-saving.
A fire protection coating for concrete delays the heating of concrete and reinforced concrete components for up to 120 minutes, depending on the amount applied. During this period, the thermal expansion of the steel reinforcement prevents the covering concrete from flaking off and the structural load-bearing capacity of the concrete components being endangered.
Another advantage: Compared to spray plaster, coating with Rudolf-Hensel fire protection products results in a visually appealing, relatively smooth, white surface and thus optimizes the light output of the installed lighting. In multi-storey car parks and underground garages, for example, the light source saves electricity.
