Perfect safety

For over twenty years, the company NEXT and its security doors have been synonymous with the safety of our homes and apartments. NEXT doors not only guarantee proven and time-tested security, but also high variability in design execution thanks to their construction. The surface of the doors can be made of veneer, solid wood, RAL plates, or any design materials. Each side of the door can have a different surface. The doors can also feature glazing with safety glass.

For fans of contemporary design, NEXT has prepared a real treat. The latest innovation, NEXT SD 104, presents security doors with hidden hinges and a double, but also hidden rebate, so that from the inside, the doors can align flush with the wall. This allows for countless design solutions for the doors and their surroundings.
The security of these doors is well above the level of the 3rd security class. Top parameters, such as a heat transfer coefficient Ud = 1.1, thermal resistance Rd = 0.94, and sound insulation over 40 dB, are also a matter of course.

The security doors NEXT SD 104 represent an entirely new generation of security doors. Their entire construction is made of galvanized or stainless steel and is filled with mineral insulation material. The perimeter of the door is protected by a stainless steel edge, the metal threshold is integrated into the frame and can also be made of stainless steel. Therefore, Next provides a premium 15-year warranty on the door skeleton and locking system.
