MasterLine 8 is a high-quality window system that links countless design options to best-in-class performance and unrivalled production speed.
In line with current architectural trends, the aluminum profile can be used to create large window areas that make the best possible use of incident daylight.
Additionally, for the MasterLine 8 the manufacturer places great emphasis on an optimised manufacturing process and simplified assembly of the finished individual elements.
The MasterLine 8 at a glance:
The MasterLine 8 is also an all-rounder in terms of its application possibilities. The profile system can be used not only for windows but also for French doors with different threshold solutions. Above all, very large window areas and glass fronts benefit from the stable aluminum construction and first-class thermal insulation.
The MasterLine 8 offers three design variants for different types of facades and building styles. In addition, the profile can also be designed as a block window, so that a total of four options are available.

Functional Design
The flush Functional design is – as the name suggests – above all functional. Designed without unnecessary decoration, the profile is convincing with its unobtrusive and very plain appearance.

Reinaissance Design
The distinguished Renaissance design is clearly more classic. The variant appears more angular overall and is a good choice for renovations where the original facade design is to be retained.

Deco Design
Deco is perhaps the most modern of the several design variants. Instead of restraint, it focuses on uniqueness. Bevelled edges create an interplay of light and shadow on the facade.

Block Design
The Block design is also suitable for very minimalist building styles. Here the casement frame is completely covered by the frame. The smooth profile surface makes the glass surface appear larger.
