Decoral is a process of improving the aesthetics of aluminium profiles and surfaces. It is based on the thermosublimationphysico-chemical process that causes the transition of a substance from the solid state to the gaseous state. Such technology is also referred to as thermal transfer in some industries. DECORAL can also be used for other materials (e.g. steel, glass, plastics, ceramics). The basic condition for its use is that the material must withstand a temperature of 200°C for about 10 minutes without deforming. Aluminium is an example of a material ideally suited for the use of this technology. When heated even to such high temperatures, it does not deform and returns to its original form without losing its shape. The use of thermal transfer enables the application of various patterns on the surface of profiles, including ones that resemble stone or wood surface. We have used this method to make sure that our doors and windows look as unique as possible. The use of this technique not only gives spectacular visual results, but also proves that our doors are made of materials resistant to exceptionally high.
