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.
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 features three Part M compliant door thresholds. Door frames easily fix to these thresholds using a universal moulding that’s hidden from view from the outside.
Full depth Eurogroove accommodates a wide range of standard fenestration hardware. Both window & door lock cases are also fully enclosed and don’t break through into the glazing, or beading area.
Prestige’s Thermlock® core provides exceptional thermal performance using closed-cell, insulating chambers to create class leading thermal performance, far superior to traditional polyamide thermal breaks.
Door sashes also support SFS 3D face mounted PAS24 hinges and the door midrail accommodates standard letterplates. Doors can also be manufactured with continuous thresholds that continue across any sidelights for neater installations.
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 properties 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.
Prestige features three Part M compliant door thresholds. Allowing easy access and eliminating 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.
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 doors are available in a choice of two opening sash styles; ‘Stepped’ – inspired by traditional steel windows – and ‘Contemporary’ with a more modern minimalist aesthetic. As all our systems share common components and are designed with consistent aesthetics and features, ou can confidently specify from across our range of products.Confident that aesthetics, colours, styles and sightlines will match perfectly across a project.
Sheerline’s cills, ancillaries and corner posts, also feature Thermlock® 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.
Manufactured in the UK, we design and make every aluminium and moulded component so we have the control to offer you unbeatable service. Sheerline profiles are available in five working days from a stocked range of 12 colours.
