The Classic Range

The Classic range is designed to maximise your views and flood your home with natural light, thanks to its ultra-slim 59mm sightlines.

Perfectly suited for both contemporary builds and heritage restorations, these windows combine the latest technical innovations with peerless aesthetics. They offer a refined, minimalist look that ensures the focus remains on the glass and the scenery beyond, without compromising on performance.

Sheerline’s cills also feature this same technology coupled with innovative inbuilt weather sealing that keep draughts and rain safely outside.

The Prestige Range

The Prestige range stands as our most versatile window system to date.

Specifically engineered to accommodate exceptionally large apertures, it allows for expansive spans of glass that transform any space. Available in an extensive array of styles, the Prestige system is perfectly suited for the widest possible range of projects—from ambitious modern self-builds to traditional home renovations.

We’ve also designed out the stepping of misaligned corners, allowing each Sheerline window to be individually hand tuned to perfection. Leaving you with the perfect balance of understated refinement and exacting quality standards.

Thermlock®

The Prestige window range seamlessly blends the clean, architectural lines of aluminium with exceptional thermal performance, achieving up to an A+ Window Energy Rating.

At the heart of every window is our innovative Thermlock® multi-chamber design. Hidden from view, this closed-cell insulating chamber acts as a superior thermal break, outperforming traditional polyamide alternatives. When combined with high-performance glazing, it creates class-leading insulation that protects your home against the harshest UK weather.

Even the details are engineered for efficiency; Sheerline cills feature this same advanced technology, coupled with integrated weather sealing to ensure draughts and rain remain firmly outside.

Available In A Wide Range Of Colours

Our range is available in twelve powder coated colours, with the option of choosing a different colour for the interior to help you find the look that is right for your property. With three metallic effect finishes available in our distinctive Paragon range for the ultimate durable and stylish finish.
