1. Because the threshold system was not designed for water and air insulation, it would take water and dust inside the house.
2. Old door systems made by bending the November-wing system from sheet metal cause problems such as rust, rot and paint over time.
3. Rubber gaskets used in the sash-moldings system lose their sealing properties due to cold and hot factors over time and begin to harden. This causes energy and sound problems at the door.
4. Since the external tightening moldings method is used, the moldings are installed by squeezing the wall from the outside to the inside with the foam or mortar filling method, this method is a method that is difficult both in manufacturing and in installation and causes the door to sag.
5. It provides a stepped image with an externally tightening moldings.
6. Since the external hinge system is used and the hinge is on the outer axis of the door, the hinge pin and screws are easy to reach and detachable. Design of hinges as a requirement, it makes the door sag from 1mm to 5mm. This sagging causes contraction over time. This contraction disrupts the settings of the door over time. It can cause rust on the metal hinge pins from the inside. Since the welding method is used,the sheet, which is 1 mm thin, can rot and break at the welding point.
7. The biplane method is divided into a main wing and a juvenile wing, and the juvenile wing adapter provides insulation and visual impairment. With prolonged use, the door may cause working disorders.
8. In special door designs, fixed glass on the side and top does not provide a rigid image in the applied methods and incompatible methods should be preferred.
9. Over time, it causes problems such as opening and playing from 45° junction points due to wing weight.
10. Because different sheet metal bends or different methods are applied in door spaces that require double wings, single wings or pivots in the same building or structure, different methods are used in the structure
it creates a perception of the door and creates an appearance disorder.
11. There is a loss of energy, which is very important for all mankind and the world.
12. Since the sheet metal manufacturing management used is not resistant to external environmental factors, it will replace the aluminum material material that is resistant to renewable external environmental factors shrinking. Teodoor hinge is specially designed for this door and is a design far above the usual hinge system. With this hinge design, there are no internal and external steps on the door. It provides a smooth ( flat) appearance. This is a design that increases insulation.

1. The threshold of 10 mm between the insulation and seals the system to design the system with the guillotine mechanism will rain from the outside with a threshold are not taken in the future by rain or wind pressure powders. Thanks to this, it is very convenient to use it in outdoor doors.
2. Because sheet metal is not used, it never rots, rusts and fades, it always looks fresh and new, like on the first day.
3. The sealing system used is 7 times more than normal door systems.
4. The November system is November into the wall with a blind case or directly into the concrete and mounted in a balanced way this method prevents sagging and working disorders in the door.
5. With its November-made design, it provides a flat image with a case-wing and wall. This design has brought aesthetics to the forefront. Aluminum moldings are preferred even if external clamping moldings are used and do not require wall filling.
6. Since hidden hinges are used, they are never visible from the outside, do not sag-elongate. Teodoor hinge optionally provides a door push and close mechanism inside. Thanks to this, it automatically turns itself off when the door is opened. Each hinge has been tested with 400 kg and has provided maximum strength. 3 Hidden hinges are used on a Teodoor door. A total wing weight of 1200 kg
7. In the double-wing design, the hem by designprovides a face-flat design. It does not cause any significant disruption in the insulation. It stands integrated with the door. It provides high security. It also does not open any interference from the outside with the slider lock method from the bottom and top. It does not take air or water
8. The application of fixed glass methods on the side and top integrates with the door and stops both sides, thus providing maximum aesthetic appearance.
9. the 45 degree connection points are tightened by gluing the corners and mortises with a special adjustable tenon system and a special adhesive used in it. This special adhesive will never move the 45° junction points for too many years.
10. With the same profiles and the same design, the hidden hinge, pivot, single wing, double wing, fixed glass door designs provide integrity in the structure because the same products are always used in the designs. A guest who comes to the structure from a visual point of view always encounters the same image. There is no difference in doors from the building entrance to the floor apartment doors or in doors such as private meeting rooms to ensure integrity
11. By prioritizing the importance of energy and insulation, it has reduced energy loss to a minimum with its design. With this design, it is aimed to recover 75% of the energy lost in the doors.
12. Aluminum, which is a young mine, is recognized and actively used in the defense industry, aviation, machinery industry and the health sector. It has become a mine that has been hardened in thermal furnaces and used for many years without damage.
