The Unique Window Design

Published 30 June 2018 by Sternfenster

The StyleLine range, exclusive to Sternfenster, stands in a class of its own when it comes to function and form. Members of the Sternfenster Approved Installer Network can offer their customers a window that captures the charm of a traditional timber design, brought into the modern day by the latest uPVC technology.

Not only do they offer a superior standard of design and quality than other uPVC window designs on the current market, they offer a unique aesthetic that really achieves a competitive edge. This comes in the form of a seamless finish of the sash and outer frame, which allows for a beautifully consistent aesthetic across the whole window design.

This appearance is made possible by a unique, state-of-the-art Seamless Quad Welder from Graf Synergy. As the UK’s first fabricator to use this system, Sternfenster is able to offer their Installers a standard of product that stands out in the current market. With this design, it’s never been easier to offer homeowners flawless design and stunning aesthetics.

StyleLine Windows


The revolutionary welding process that is used across the StyleLine range not only allows it to achieve an outstanding appearance, it also enables them to offer a stronger and more resistant frame. This is made possible by the fact that the manufacturing process eliminates the grooving stage, avoiding any loss of vinyl at the corner joint.

Alongside this, StyleLine windows meet the modern demands that homeowners have come to expect from their home improvements. They achieve market-leading standards of thermal efficiency, security, durability and performance. They are sure to be a fantastic addition to the product offering of any installer.

Nathan Court, Sales and Marketing Manager at Sternfenster, commented on the importance of the StyleLine window range:

“We know how competitive the market can be, which is why we’re constantly looking for ways to help our Approved Installers to stand out. The StyleLine window is a demonstration of this, operating as a result of a unique and cutting-edge manufacturing process to secure the best standards.”
