Doors
Slim-profile thermally broken aluminium doors with traditional proportions. The steel-look aesthetic of heritage aluminium suits period properties and conservation areas where modern UPVC would look out of place.
Personalise Your Door
Door colour: Black
Standard colours
Inside and outside finishes can be discussed separately where the chosen range allows.
Heritage hardware finish: Black Antique
Heritage aluminium doors can use more traditional-looking handles, letterplates, knockers, and cylinders, but the finish still needs to sit naturally with the slim glazing bars.
Made to measure. We show the relevant colour and hardware options during your survey before anything is finalised.

Heritage Specification
The heritage aluminium page keeps the emphasis on period-sensitive specification, using carefully selected reference visuals to support the key configuration, glazing, and hardware decisions.
The important heritage decision is how the opening should read from the elevation: a simple single leaf, a balanced pair, or a broader composition with matching sidelights.
A single-leaf heritage door keeps the elevation restrained and works well on side returns, porch replacements, and narrower period openings.
Double doors suit reception rooms and garden-facing period openings where the central opening is part of the character of the facade.
Sidelights keep the same narrow heritage frame language while widening the set and bringing more light into halls, side returns, and rear extensions.
Glazing has a major effect on how authentic the final set feels, especially on street-facing or conservation-sensitive properties.
Clear insulated glass keeps the frame visually light and usually works best where the property already has privacy from its setting.
Decorative and leaded routes can help the new door sit more naturally alongside existing fanlights, stained glass, or neighbouring period joinery.
Obscure glass is a strong option on side entrances and street-facing doors where privacy matters but the opening still needs to borrow daylight.
Heritage-appropriate bar layouts help the final set read more like original steel joinery than a generic modern aluminium door.
Technical Details
Product fit
Heritage aluminium doors are specified when the frame needs to look slimmer and more traditional than a standard residential door. They suit period openings, side returns, internal-external transitions, and projects where glazing bars or darker powder-coated frames are part of the brief.
Optional Upgrade
Heritage aluminium doors are all about slim divided glazing and a considered frame line. Integral blinds can be useful on larger glazed sections or side screens where privacy is needed without softening the steel-look style.
A survey-led upgrade for heritage-style glazing where the frame rhythm should stay visible.
Magnetic integral blinds
A slim magnetic slider raises, lowers, and tilts the blind inside the sealed glass unit.
Electric integral blinds
Remote operation suits larger panes, harder-to-reach glass, and cleaner contemporary rooms.
We check the glazing bar layout and pane sizes carefully because not every divided-light design is a good fit for integral blinds.

If this looks like the right fit, we can survey the opening, confirm the specification, and price it properly for your home with no obligation.
Heritage aluminium doors are the correct choice when the property requires the slim sightlines and traditional proportions of original steel casement doors, but without the corrosion, weight, and maintenance demands of steel. Thermally broken aluminium profiles from an approved manufacturer deliver modern U-values and weather sealing inside a frame that reads as period-sympathetic from the street. The steel-look finish is available in deep heritage colours including black, dark green, dark blue, and dark bronze, all of which can be matched to existing windows or surrounding ironwork.

Where UPVC proportions look too modern
Thermally broken aluminium construction prevents cold bridging at the frame and achieves significantly better U-values than non-thermally broken steel equivalents. Double and triple-glazed units are available, with low-emissivity coatings and argon filling to optimise thermal performance for the orientation and use.
Heritage aluminium doors are fitted with multipoint locking as standard. Cylinder locks can be specified with anti-snap, anti-pick, and anti-drill protection. The thermally broken aluminium frame is inherently rigid, resisting frame flex that can be exploited on lighter door systems.
Frame colour, ironmongery finish, leaf configuration, and glazing specification are all selected at quote stage. Custom RAL colours are available to match existing metalwork or to meet conservation officer requirements. Decorative leaded and obscure glazing options suit period interiors and are available across all door configurations.
All CII door installations are covered by our 10-year installation guarantee. Heritage aluminium doors are supplied through our approved partner and installed with the survey, specification, and handover managed by CII.
Heritage Reference Points
Exact heritage-aluminium photography is still limited, so this page now uses clearer reference-led visuals to support the configuration, glazing, colour, and hardware story without overstating what is product-specific.
Whether the project needs a single leaf or a symmetrical pair, the aim is keeping the elevation disciplined rather than over-complicating the opening.
Leaded, patterned, and heritage-led glazing choices do a lot of the work in helping a new set feel right on a period facade.
Black, bronze, deep green, and dark blue tend to feel most at home on steel-look and conservation-minded briefs.
The goal is traditional visual character on the face of the door, backed by locking confidence that still feels current.
