Sheerline Prestige Windows are designed with an innovative Thermavic® multi-chamber thermal break. This technology significantly enhances insulation, helping to achieve impressive U-values as low as 1.3 W/m²K with double glazing and 0.9 W/m²K with triple glazing. This ensures excellent energy efficiency, keeping homes warm and reducing heat loss.
With sightlines starting as slim as 88mm, these windows maximize natural light entry, creating a brighter and more open interior space. Their refined aluminium frames deliver a sleek, modern aesthetic, making them ideal for both contemporary and traditional homes.
Prestige windows feature robust security measures, including multipoint locking systems and unique hinge protectors. The integrated design also ensures that lock cases are fully enclosed, preventing potential weaknesses in the frame. This system provides peace of mind with advanced protection against intruders.

Security is a top priority with Sheerline Prestige Windows, incorporating multipoint locking systems and concealed hinge protectors for enhanced safety.

Sheerline Prestige Windows are crafted using premium aluminium, a material known for its strength and long-lasting properties. The frames are built with a patented construction method that ensures each window is tightly bound, eliminating issues with misaligned corners and boosting structural integrity. This makes them highly resistant to wear and tear, even in harsh weather conditions.
In addition to their robust build, these windows are finished with durable powder-coated colours or anodised finishes, which resist fading and scratching over time. This means your windows will retain their aesthetic appeal and performance for many years with minimal maintenance.
With Sheerline Prestige, you can choose from a range of styles to suit your home’s architectural look. Whether you prefer a traditional ‘stepped’ sash inspired by classic steel windows or a more modern ‘contemporary’ design, there’s an option for everyone. Additionally, the flush sash option provides a clean and seamless appearance, with both the outer frame and sash perfectly aligned.
The Prestige windows also offer a variety of colour options, from subtle shades like Cream and Agate Grey to bold finishes like Jet Black and Pastel Turquoise. This level of customisation allows homeowners to create the perfect look, both inside and out.
Sheerline Prestige Windows are manufactured using some of the most energy-efficient processes in the UK, with sustainability at the heart of production. Aluminium is one of the most recyclable materials, with up to 75% of all aluminium ever produced still in use today. This makes Sheerline products a responsible choice for environmentally conscious homeowners.
Additionally, the energy efficiency built into every window helps reduce the carbon footprint of your home. By lowering your energy consumption with thermally efficient windows, you’re contributing to a greener future while enjoying a more comfortable living space.
