theft proof class 4 Security interior door

Apartment Soundproof Front Doors

Interior Security Doors for apartment/flat. Steel doors decorated with filling PVC film patterns are used for the security of inside premises. The sash of the door is made from folded steel profiles and external protective 1,5 mm thick steel plating, 50 mm stone wool filling, insulation spacer glued onto the sash of the door and an extra spacer fixed on the jamb (door frame) double insulation.

Panels (MDF) coated with PVC film of various colours are used for the finishing/decoration of the door. The elements of the panel are first of all cut out during the manufacturing process, then each element is laminated separately, and only after that the panel is assembled into an integral pattern. Patterns of exclusive design and forms are created in this manner.

The hinges are with supporting bearings. Stationary tempered pins protect the door from being taken out after cutting the hinges thus ensuring greater security.
The jamb (door frame) is made from folded steel profiles. The metal construction of the sash and the jamb (door frame) are painted with powder paint.
