At E&A Windows, our Heritage aluminium doors offer versatility that bridges the gap between classic and modern design, providing the perfect solution for those seeking a period aesthetic with bang up-to-date performance.
By utilising a range of heritage-inspired colours and authentic finishes, we create durable, high-performance doors that sit in perfect harmony with traditional architecture. In Hertfordshire’s many conservation areas, our Heritage doors are the ideal replacement for old and draughty doors to keep your property secure and your energy bills low.
While traditional materials such as timber are often required for heritage approval, aluminium doors are increasingly permitted within conservation areas, provided the design is handled with architectural sensitivity and is engineered to respect historical proportions.
While approval depends on the local authority, the primary concern for many planning authorities is the preservation of a building’s character.
Particularly suited to Victorian and Art Deco architecture, our doors are a proven choice for high-end renovations and heritage refurbishments, allowing homeowners to preserve the historical integrity of their property while benefiting from modern performance.
What are the best doors for period properties?
If you’re considering replacing the doors in your period property, you’ll want to ensure that you invest in high-quality replacements to ensure your home stays warm, quiet, and secure.
Original, single-glazed doors often struggle with heat loss and ageing timber. By choosing a bespoke aluminium replacement, you can enjoy an energy-efficient home that looks exactly as the original architects intended.
What are Heritage aluminium doors?
The Heritage range is specifically engineered for sensitive refurbishment and renewal projects where planning demands are strict. Designed as a high-performance, like-for-like replacement for traditional doors, they offer classic proportions making them the ideal solution for Victorian and Art Deco properties, including those with Listed Building status.
Trusted by local authorities across the UK, Heritage aluminium doors are the definitive choice for homeowners seeking the perfect balance of period charm and contemporary thermal efficiency.
The thermally-broken aluminium frames ensure your home remains warm and draught-free without compromising its historic character. Heritage aluminium doors are versatile and can be used for both internal and external applications, making them suitable for a wide range of designs while preserving the traditional architecture.
The Heritage range also includes aluminium patio doors or French doors featuring slim sightlines, classic hardware, and profiles that replicate the appearance of original steel doors, making them ideal for traditional and listed properties.
Can I install an aluminium door in a conservation area?
In a Conservation Area, the primary rule is that any change must “preserve or enhance” the area. Your choice of door is often governed by restrictions on what you can change without explicit planning permission, and in most UK conservation areas, the “like-for-like” rule applies.
Typically the door must match the architectural era of the street with the following examples:
- Georgian: Look for six-panel designs with symmetrical proportions and a fanlight (the window above the door).
- Victorian: Often four-panel designs with deep mouldings and perhaps stained or etched glass in the top panels.
- Astragal Bars: If the door has glass, the “bars” (the strips dividing the panes) must be the correct width. Planning officers prefer “authentic” or “putty-line” bars rather than bars trapped inside the double glazing.
The benefits of aluminium over other materials
If you want double-glazed doors in a conservation area, you cannot always use standard units as they are too thick, giving away their modern nature. As aluminium is much stronger than uPVC, the frames can be made much narrower while still supporting the weight of double or triple glazing.
The finishing touches
Some conservation areas have a prescribed colour palette and finish. Standard white or high-gloss aluminium is rarely permitted; instead, authorities prefer subtle, matt-powder coatings in heritage-inspired colours. We offer shades such as Anthracite Grey, Agate Grey, Lichfield Green and premium woodgrain textures to deliver a traditional aesthetic.
For ironmongery, planning officers look for unlacquered brass, forged iron, or bronze rather than modern bright chrome. Our Heritage aluminium doors boast an eight-shade anodised palette. Whether you require the warmth of bronze and gold or the minimalism of silver, grey and black, our finishes offer a flawless match. By merging the visual of traditional anodising with the advanced resilience of modern powder coating, the finish is superbly durable.

Do heritage aluminium doors require special maintenance?
One of the greatest appeals of heritage aluminium doors is that they require significantly less maintenance than almost any other material. Because they are finished with a high-grade, baked-on polyester powder coating, the frames will not rot, rust, peel, or require repainting.
To ensure they last for their full 40–50 year lifespan, there are a few simple steps you should follow:
General Cleaning
Avoid abrasive cleaners, solvent-based products, or power washers on aluminium front doors. Simply wash them twice a year with warm soapy water and a soft cloth to preserve the “as-new” finish of the powder coating.
Lubricating the Hardware
The hinges, handles, and multi-point locking mechanism need minimal maintenance with a little attention once a year. Apply a light spray of oil or a specialised “lock lubricant” to the moving bolts to keep the action silent and effortless. Avoid WD-40 for long-term lubrication as it can dry out and attract gunk.
Gasket and Seal Care
Over time the rubber seals (gaskets) can become dry. Our expert team advises homeowners to use a tiny amount of silicone spray on a cloth to wipe the gaskets once a year; this keeps the rubber supple and prevents it from sticking to the frame in extreme heat, ensuring excellent quality maintenance.
Are heritage aluminium doors secure?
Engineered for ultimate peace of mind, our aluminium doors integrate advanced multi-point locking systems with high-impact toughened glass to create a formidable barrier for your home. You can sleep soundly knowing your Hertfordshire property is protected by industry-leading security that meets the most exacting modern standards.
How energy efficient are heritage aluminium doors?
Modern aluminium systems have improved energy efficiency through the use of polyamide thermal breaks. By integrating this high-performance insulator between the internal and external frames, we create a thermal barrier that effectively eliminates the “cold bridge” typically associated with metal doors and windows.
By maintaining a warmer interior profile, the system drastically reduces the risk of condensation and cold spots, ensuring your home remains a dry, comfortable, and healthy environment throughout the year.
What is the lifespan of Heritage aluminium doors?
One of the most compelling advantages of aluminium is its resilience, contributing to its timeless appeal. Unlike other materials, aluminium does not rust, rot, or warp, allowing doors to maintain their structural integrity almost indefinitely.
While uPVC and certain softwoods typically require replacement after approximately 35 years, high-grade aluminium systems boast a lifespan of 45-50 years or more.
This not only offers superior long-term value but also reduces the environmental impact associated with manufacturing and installation. When you choose aluminium, you are investing in a low-maintenance solution designed to perform for the long term.
Can heritage aluminium doors be customised?
We believe your entrance should be as unique as your home itself. With an extensive palette of bespoke colours, glazing configurations, and hand-selected hardware, you have the creative freedom to design a door that perfectly complements your property’s architectural character.
