G-LINE 74 system has a wide range of applications: standard windows and doors (including balcony doors), renovation windows (available in two fin heights: 75 and 87 mm) and PSK tilt-and-slide patio doors. Non-standard solutions, such as arches, circles, rakes, and trapeziums, are also available.

The tilt-and-slide PSK patio doors are a very popular solution available in almost all window and door systems offered by Amex-Bączek. On the one hand, they do not take up space after opening (sliding) and give a wide passage to the balcony or patio. On the other hand, you can use the tilt function – for example, when you just want to ventilate the room and at the same time maintain an adequate level of safety in your home.

A visible rail is mounted to the frame, on which trolleys mounted on the inner frame of the operable sash and hidden under the covers are driven. The tilt-and-slide doors can only have a high threshold.

Roller shutter casings

Roller shutter casings are a very popular solution especially in Italy. We offer two types of casings: renovation casings (cassonetti da restauro) and casings used in new buildings (cassonetti monoblocco). We invite you to see our full offer of windows and doors for the Italian market [click].

Renovation roller shutter casings

They are most often used in renovated buildings. Thanks to their universal design, renovation roller shutter casings can be applied to existing casings without the need to replace the roller shutter. They are installed inside the room. Thanks to the multi-chamber profile, cassonetti da restauro are characterized by high strength and aesthetic appearance, and the ease of segmental joining of profiles allows to obtain any size of the cassette. The casings can be the color of the window, any available veneer from the V-LINE palette or any RAL color.

Roller shutter casings for new buildings

Monoblocco are roller shutter casings mounted in the window which open together with the window. They are used in new buildings. Monoblocco can be ordered with full equipment – roller shutter guide, roller shutter, as well as with the option of the motor roller shutter operation (automation). They are also available in the window color, the V-LINE window and door system veneer palette, and the RAL colors.

Zgrzew Contourline

Contourline seam

In 2018, we launched a new production floor with two modern process lines. Since then, Amex-Bączek windows and doors stand out on the market with a very thin and aesthetic Contourline seam.

Nodo ridotto,
or Italian patent for nice windows

A popular solution, especially in Italy, in double-leaf windows is the reduced joint (in Italian nodo ridotto), which is a special construction in which a sash without an up-stand replaces the floating mullion. In practice, this solution offers a floating mullion that is narrower than standard one, resulting in discreet illumination of the interior. We offer nodo ridotto in the G-LINE 74 and G-LINE 82 systems.
  • narrower than the standard floating mullion
  • discreet interior lighting
  • handle mounted symmetrically

In PVC window and door systems, we use Siegenia fittings

In PVC windows and doors, we use fittings of the Siegenia, a brand well known in the world. We refer to the fittings from the TITAN AF series, which already in the standard version guarantee a high level of safety.

Standard colors (veneers)

G-LINE 74 window and door system is available in a wide range of veneers. You can choose from woodgrain imitation, and various metal and stone imitation veneers. Additionally, the natural wood effect is provided by Realwood veneers. You can also match the color of the core (profile) with the color of the window. Three shades are available: white, brown, and caramel.

Realwood veneers perfectly image genuine wood grain. They are significantly less glossy than standard veneers. As a result, they give G-LINEAR 74 windows a fresh and natural look. The Realwood palette consists of six hues: RAL 7016, scandinavian oak, RAL 9010, ginger oak, honey oak, amaranth oak and turner oak malt.

Dedicated handles

We dedicate two types of door handles to the G-LINE 74 windows, depending on the customer’s taste and needs. For those who value elegance, we recommend the Medos DUBLIN handles, which are available in many colors and two variants – brushed or sandblasted aluminum. In turn, for customers requiring more security, we offer Hoppe Atlanta handles with Secustik® technology. In both cases, the offer includes standard handles, push-button handles, and key handles.
