Our most thermally efficient 72/80mm system, accommodating the largest apertures, and available in the widest range of styles. Prestige windows feature a full depth Eurogroove, giving you the maximum choice in hardware options.
Our patented corner assembly method allows windows to be made on one bench, once cutting and milling has taken place, saving time. Scrap levels are also drastically reduced, saving you money.
Beautiful, repeatable corners that are tuneable, eliminating misaligned frames - all thanks to our patented corner assembly.
Prestige windows have a U-value as low as 0.9W/(m2K) when specified with triple glazing, 1.3W/(m2K) double glazed, also achieving an A+ WER (Window Energy Rating)
With a full depth Eurogroove, Prestige is our most versatile system, carrying the widest range of window styles and glazing options, offering a choice of small, intermediate and large outer frames.
Can accommodate the largest spans and biggest windows. 72mm front to back as standard, – in-line with the Classic flush profile width – allowing the systems to be joined. 80mm for Flush frames.
Available as single and French door (French also available as flush with sidelights and flags, with full mid-rail options).
Prestige combines aluminium’s clean lines with exceptional thermal performance for up to an A+ Window Energy Rating.* Our innovative Thermlock® multi-chamber thermal design, hidden away inside each window and door, helps keep you and your property well insulated against the worst of the UK weather. This closed-cell, insulating chamber acts as a thermal break and works in conjunction with high performance glazing to create class leading thermal performance, far superior to traditional polyamide thermal breaks. Sheerline’s cills also feature this same technology coupled with innovative in-built weather sealing keeping draughts and rain safely outside.
Thermal transmittance, also known as a U-value, measures the rate of transfer of heat. The better-insulated a window is, the lower the U-value will be. Available with up to 44mm triple glazing for the ultimate thermal performance. Triple glazing can also provide exceptional acoustic dampening to block out unwanted noise.
Our patented corner jointing method creates exceptionally strong frames, maximising the inherent strength of Sheerline’s aluminium construction. A full depth eurogroove also enables you to offer the latest high security, multipoint locking - helping keep customers and their home’s safe and secure. Additional features like unique hinge protectors also help create exceptional levels of security. Prestige’s clever integrated design also ensures both window and door lock cases are fully enclosed, meaning they don’t break through into the glazing, or beading areas - which could weaken the integrity of the frame. So for customers looking for extra peace of mind as standard – we have them covered. For added peace of mind choose our laminate glass upgrade – for Secured by Design accreditation* – the official UK Police initiative ‘designing out crime’ through physical security.
Our patented construction method – using threaded screws to bind corners tightly together – helps eliminate misaligned corner issues that can occur on ordinary aluminium frames. Allowing each Sheerline window to be individually hand tuned to perfection. This innovative corner jointing method also does away with the need for crimping and specialised machinery and drastically reduces waste. Larger frames can also be assembled in situ if required.
Sheerline aluminium windows are available in a choice of two opening sash styles; ‘Stepped’ – inspired by traditional steel windows – and ‘Contemporary’ with a more modern minimalist aesthetic. Both styles are available in either our standard outer frame, or as a ‘Flush’ option that brings both the perimeter and the opening sash perfectly in-line with each other.
Sheerline’s cills, ancillaries and corner posts, also feature Thermavic® technology coupled with innovative in-built weather sealing that keep draughts and rain safely outside, help eliminate any condensation issues caused by cold bridging, and reduce the need for onsite sealing. All based on a common chassis helping to reduce product complexity. This innovative clip together approach also means dual colours are easy to assemble and stock utilisation is improved.
