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.
Styleline windows are available with a range of high performance handles. Choose window handle colours to match the property style.
Styleline windows stand out when matched with the perfect colour. We offer durable, hard-wearing colours that will maintain their vibrancy for many years. Preview our traditional and modern range to explore our wide range of colours.
We offer a range of beautiful, bespoke glazing options. Made to measure and specialist designs are available, along with solar and privacy glass options.
StyleLine windows are exceptionally strong. The uPVC material is bolstered with steel for strong reinforcement. The glazing is also internally beaded which prevents intruders from prising into the unit from the outside. All security is in line with the latest European standards, giving you complete
peace of mind that your home is secure.
Steel reinforcing, internal beading and incredible weld strength make our products exceptionally strong. The steel reinforcement of the uPVC enhances the rigidity, offering greater protection against the elements.
StyleLine windows are internally beaded in line with the latest European security standards, including BS7950 and PAS24. Additional claw locking is available for enhanced protection.
Our StyleLine windows are manufactured using state-of-the-art technology, which enables us to produce uPVC products of superior design and quality. These windows provide you with a consistent, high quality finish throughout.
Every window goes through a stringent manufacturing process to provide you with a flawless design and stunning aesthetics.
StyleLine windows are unique in that our technology completely removes the grooving stage. Our machinery removes the corner joint which provides a unique flush finish.
