The THERMO-ALU INOX series is a product with an increased thermal insulation (Ud = 1.0W/(m2*K). It is based on ALUPROF MB-70 PASSIVE systems with side panels.


The characteristic feature of this series is a separate layer of corroded Corten steel that is mounted on the outside of the door leaf. It is made of a steel grade that is characterized by high resistance to weather conditions.


Under an actual layer of rust, Corten steel forms a dense layer of phosphates or sulfates. This barrier protects the surface from further corrosion. The layer of rust begins to form itself in the second week. The process may take up to 3 years. The color of rust is initially light brown, but it gets darker over time. It is important that the surface should dry out after wet periods. If the steel is exposed to permanent moisture the protective layer is not effective and Corten steel rusts just like normal steel. Depending on weather and environmental conditions, different rust colors are formed on the surface, even on identical parts of the material. This is not a defect, but an advantage, therefore, it does not entitle to complaints.

Note - the layer of rust that is firstly formed is not permanent and may therefore leave rust marks on adjacent building materials.


The door width and height can be extended with the help of additional side panels and upper transoms. Those can be made in plain glass, with a decor-matt or simply frosted glass with a pattern matching the pattern of the door leaf.


The multi-point lock FUHR is used for locking. It has many locking and control configurations.
Hinges: the choice of wing or roller hinges (WALA) and concealed hinges (AXXENT).
Glazing in the door leaf: Four-pane glass of Ug = 0,5 W/(m2*K).
Thickness of polyurethane foam in the leaf: 70 mm.


Additional options to increase the burglary resistance of the door:
- 6D-C class inserts,
- anti-burglary protection of hinges,
- the P4 class of the glass.
