VEKA Softline 76 AD PVC Window System

VEKA Softline 76 AD PVC Window System

The VEKA Softline 76 AD PVC Window System is a PVC-U profile system with a 76 mm system depth and Class A wall construction. AD identifies its two-stage sealing arrangement, with two sealing levels around the frame and sash. This creates the defining construction detail of the 76 AD version and gives it a clear profile identity for window designs that specify this sealing format. The profile accepts glazing up to 48 mm thick, making it compatible with a range of glass build-ups within the system's dimensional allowance. VEKA also publishes minimum view widths of 71 mm for a fixed sash and 112 mm for frame and sash together. Those profile dimensions describe the visible face around the glass and help establish the balance between frame and glazed area. A special sash profile is available for adhesive technology, offering another documented construction route for fabricators. The PVC-U profile provides a consistent base for the frame, sash, seals, and selected glass, while the system's 76 mm depth and two-stage seal arrangement define its main construction characteristics. In a window elevation, these details influence both the visible sightline and how the sash is assembled within its frame.

Two-Stage Sealing and Glass Accommodation

Softline 76 AD is designed as a profile system for fabrication into windows, with the selected profile combination and glass build determining the completed unit. VEKA lists a sash size reference up to 1400 mm wide by 2500 mm high, and a Uf value of 1.2 W/(m²·K) for the profile system. Uf describes the frame profile, distinct from Uw for a complete window. The two-stage seals are central to the AD profile design, while the 48 mm glazing allowance gives fabricators room to select compatible glass within the system limit. VEKA gives separate minimum view widths for fixed and combined frame-and-sash profiles, helping define the visible border around each glass field. The special sash for adhesive technology adds a distinct fabrication option while retaining the Softline 76 AD profile identity. The published system references and available choices depend on the selected profile combination, glazing, hardware, size, and assembly. The frame and sash widths establish the visible proportion around the glass, while the two-stage seals define the junction between the opening parts. The result is a PVC window design whose appearance comes from the frame geometry and glazing proportion, with the selected glass and fabrication details completing the finished unit.
