Why StyleLine?

Exclusive to Sternfenster, the StyleLine range of windows and doors sets the standard for performance in the industry.

We manufacture StyleLine windows with state-of-the-art technology. Our modern uPVC windows outperform other products in both quality and performance.

Our windows undergo stringent quality control at our facility to ensure every design has a flawless finish. We supply nothing short of the best.

StyleLine windows have a smooth finish. With no grooving stage, there is no loss of vinyl at the corner joint. This trademark makes our windows unique.

There is no corner cleaning stage. The excess plastic is pushed inside the chambers for a tidier, more appealing finish. We transform the manufacturing process to build better.

With multi-point shoot bolt locking, internal beading and superior weld strength, StyleLine windows are extremely secure.
