Introducing Sheerline

Building on years of experience, we’ve incorporated many new innovative ideas to create the Sheerline range of window, door, bi-fold and lantern systems. Creating warm, slim and ultra secure products, designed for discerning homeowners who aren’t willing to compromise. Built around our innovative Thermlock® multi-chamber thermal break, Sheerline windows use a patented construction method that creates the most beautiful, high quality finish possible. Stylish, safe and sustainable – and offered with unbeatable service levels – Sheerline is the right choice for homeowners

Prestige Doors

The Prestige door range is a thermally efficient 72/80mm system, accommodating a wide range of styles and featuring a full depth Eurogroove, giving you the maximum choice in hardware options. Available in the same range of 12 colours as the rest of the Sheerline range

High quality, innovative and versatile, Sheerline doors let light flood in to open up interiors

The Prestige system covers both single and French doors, so you can be sure of finding the perfect entrance for your home. We offer three thermally broken aluminium thresholds, (alongside continuous frame options), which have been tested to the requirements of Part M, ensuring there’s no weak point in the thermal performance of your door and helping prevent condensation build-up. Continuing the high end aesthetics, no fixings are visible in the threshold, and designs follow the same clean, refined looks of our windows

Low Thresholds

Prestige features a choice of three low thresholds that have been tested to the requirements of Part M, alongside continuous frame options. These allow easier access, while reducing trip hazards. Door frames fix to these thresholds using a universal moulding that’s hidden from view from the outside. A cover strip continues the high end aesthetics, hiding the fixings, but can be slid under the moulding to aid removal if required


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

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
