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

Styling Options

With a choice of traditional or contemporary styling 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. You can draw on our experience if required to find the one that resonates best with your home’s character. A range of Georgian bar options are also available.

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

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
