The metal armouring is made from 2 steel plates 1 mm thick, that link together with vertical neuroses and create an impenetrable sourface. Internally you can find a layer of glass wool that provides thermal insulation.
     The doors's steel frame is covered in electrostatic paint so it can easily bare all climatic conditions.
The final layer consists of a laminated leaf (MDF), used mainly for giving the whole system it's unique aspect and identity.
The door is also fitted with:
-double perimetric ruber seals, providing heat and sound insulation.
-180 degrees peep hole.
-special mechanism allowing a small opening of 10%.

The major advantage of these doors is that they are very light compared with other burglarproof doors.
