At Sternfenster, we are proud to bring the unique StyeLine door collection to trade and homeowners across the UK. These contemporary uPVC doors provide homes with stunning aesthetics and unbeatable all-round performance. StyleLine doors are unlike any other composite doors available on the market today. Keep reading to learn exactly what features make these innovative doors so unique. 

Seamless Corner Joints 

Traditional timber doors have a timeless appearance, and many modern homeowners continue to favour the charming look of a classic wooden frame. There are many uPVC and composite doors available today that have been manufactured to mimic the look of timber, but no product achieves this quite as well as StyleLine doors. 

To achieve a seamless and authentic-looking corner joint, the StyleLine profiles are manufactured using cutting-edge welding technology. Sternfenster is the first fabricator in the UK to use the revolutionary Seamless Quad Welder from Graf Synergy to create strong, sleek and stunning door designs.

Unbeatable Timber Appearance 

While classic timber doors have a charming visual appeal, they are also prone to several issues. Old wooden doors were not built with the natural elements in mind and are often prone to weather damage, such as rot, shape distortion and paint discolouration. 

The doors in the StyleLine range are manufactured using high grade uPVC and are built to withstand the worst weather conditions. The durable uPVC doors are finished with wood grain foils, providing homeowners with a beautiful timber appearance. StyleLine doors look as close to the authentic wooden door appearance as possible; they are by far the best timber-replica doors available on the market today. 

Superior Security 

Homeowners are spoilt for choice when it comes to secure doors for their homes, but StyleLine doors offer unmatched levels of property protection. When choosing to invest in a StyleLine door, homeowners can have total peace of mind that their property, belongings and family are as safe as possible. 

Featuring multi-point shootbolt locking and clever key locking handles as standard, all StyleLine doors work as a protective barrier between homes and potential criminals outside. These robust doors are also manufactured with steel reinforcing, internal beading and revolutionary welding techniques. Thanks to cutting-edge manufacturing methods, StyleLine doors are extremely strong and offer unmatched levels of home security.  

Enhanced Energy Efficiency 

With energy prices currently through the roof, many homeowners across the UK are looking for ways to make their homes more energy efficient. Upgrading underperforming windows and doors to models with a higher energy rating is an easy way to boost a property’s thermal performance. Homes lose a large percentage of heat through their windows and doors, and energy efficient models are designed to minimise this common problem.

StyleLine doors offer exceptional levels of energy efficiency, more so than the majority of doors available on the market today. Available with ‘A’ rated double or triple glazing, these uPVC doors offer exceptional insulation and effectively reduce heat loss. Our modern manufacturing methods allow us to create doors with large areas of energy efficient glazing, meaning homes can benefit from extra natural light alongside enhanced thermal performance. 

With a StyleLine door installation, homes will stay warmer for longer and will cost less to heat. As the doors provide exceptional insulation and reduce heat loss, they can help homeowners save money on energy bills and also reduce their carbon footprint.

Robust & Weather Resistant 

StyleLine doors are unique as they are built with a combination of unrivalled weather protection features. uPVC doors are built to last several years, but poor weather proofing can lead to premature deterioration, and the overall performance of the door can suffer. StyleLine doors feature low sightline gaskets, double weather-seals and a super space bar. Thanks to this extensive weather proofing, these durable doors will offer peak performance all year round for decades to come. Whatever the weather may be, homeowners can count on their StyleLine door to continue to look and perform at their best.
