Tostem Grandel 2 Type 152 is an entrance door made entirely of metal. Although it is an industrially manufactured product, its filigree appearance makes it look as if it had been made from wood by craftsmen using traditional methods. The door panel with its lattice-like structure looks sophisticated but has been designed to be discreet so that it can adapt with subtlety to contemporary architecture. The door comes with a very high level of heat insulation and thus helps to save energy, particularly valuable in regions with large variations in temperature.
