VEKA Softline 82 MD PVC Window System

VEKA Softline 82 MD PVC Window System

The VEKA Softline 82 MD PVC Window System is an 82 mm multi-chamber PVC-U profile with a central third seal between frame and sash. This MD construction creates a three-level sealing layout and distinguishes the profile from the two-seal 82 AD design. Its profile geometry surrounds the glass and hardware zones, with capacity for glazing up to 54 mm thick. That depth gives the fabricator room to select a compatible glass build for the intended window while retaining the central-seal arrangement. VEKA identifies the profile wall as Class A under DIN EN 12608-1 and lists Uf as 1.0 W/(m²K) for the profile; the value relates to the profile section, not the assembled window. The proportions of the system also influence the visible border around the glazed area: VEKA gives minimum view widths of 73 mm for a fixed field and 114 mm for the frame-and-sash combination. VEKA’s MD literature offers more than 60 finish choices and exterior aluminum cover profiles as system options. A PVC finish can coordinate the frame across the opening, while an exterior aluminum cover provides another documented surface treatment for the outside face. These are range options for fabricator selection, not a statement that a particular finish comes with every window. The precise profile, glass and surface combination determines the character of the completed window.

Central seal, frame proportions, and finishes

The defining feature of Softline 82 MD is the additional seal positioned centrally between the sash and frame. Together, the three sealing levels create the MD interface within the 82 mm profile system, giving this model a different section layout from the related AD version. In a window design, that detail belongs to the profile construction; the visible result is shaped by frame-and-sash dimensions, glazing and finish. VEKA lists minimum view widths of 73 mm for a fixed field and 114 mm for a frame-and-sash assembly, providing a reference for how much profile is visible around the glass. Maximum sash dimensions are 1400 mm wide and 2500 mm high, while glazing can be accommodated up to 54 mm thick. Those figures describe system limits and dimensions. The profile’s Uf of 1.0 W/(m²K) remains distinct from any whole-window rating. Manufacturer system figures and reference values depend on the selected glass, dimensions, reinforcement, hardware and fabrication. For appearance, the manufacturer’s literature lists more than 60 finishes and exterior aluminum covers, enabling different surface treatments within the system family. A colored PVC profile can keep a consistent frame appearance, while a metal cover on the outside offers a contrasting façade-facing finish. The finish range gives the fabricator a broad palette for coordinating the frame with the building envelope, and the documented glazing capacity allows glass selection to remain part of the design.
