Stylish aluminium windows that combine exceptional thermal performance with refined looks

Choosing the right aluminium windows for your home is an important decision. An investment that makes a real difference to how warm and secure you feel, as well as improving the look of your property. That is why we have carefully designed the Prestige window and door system to combine stylish looks with the latest technical innovation. Building on years of experience, we’ve incorporated many unique features to create an incredibly thermally efficient, secure system, with unparalleled aesthetic appeal, that’s available in a wide range of colours. Designed for discerning homeowners that aren’t willing to compromise, the Prestige range is tailored for those who demand more for their homes.

Made in Britain
A range of contemporary colours

Our Prestige range of windows and doors are available in eight powder coated matt colours, as well as a high gloss white with the option of choosing a different colour for the interior to help you find the look that is perfect for your property. A further three anodised finishes are available for the ultimate durable and stylish finish.

Benefits of the Prestige System
Thermlock®

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.

1.3 U-value W/(m²K) Double glazed, 0.9 U-value Triple glazed

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.

Inbuilt Security

Our patented corner jointing method creates exceptionally strong frames, maximising the inherent strength of Sheerline’s aluminium construction. A full depth eurogroove also enables us to offer the latest high security, multipoint locking - helping keep you and your home 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 if you are looking for extra peace of mind as standard – then we have you 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.

Patented Construction

With sightlines starting as slim as 88mm, Prestige windows and doors help maximise the daylight entering your home, with crisp aluminium detailing creating a refined and architectural look. While our patented construction method – using threaded screws to bind corners tightly together – helps eliminate misaligned corner issues that can occur on ordinary aluminium frames. This allows each Sheerline window to be individually hand tuned to perfection. Leaving you with the perfect balance of understated refinement coupled to exacting quality standards, where no detail’s overlooked. Creating consistent aesthetics across every Sheerline window and door.

Style Options

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. We are happy to offer advice about which will complement your home’s style perfectly if required.
