Are Heritage aluminium windows suitable for listed buildings and conservation areas?

In many cases, yes. Our Heritage aluminium windows are designed to closely replicate the appearance of traditional steel windows, and their slim sightlines and authentic styling are often acceptable to planning authorities and conservation officers. We always recommend confirming requirements with your local planning department before proceeding.

How do Heritage aluminium windows compare to original steel windows?

Heritage aluminium windows offer the same elegant, slim-framed aesthetic as traditional steel but with significant practical advantages. Aluminium does not rust or corrode, requires far less maintenance, and performs considerably better thermally. Our systems are fitted with thermal breaks as standard, which original steel windows cannot provide.

What colour options are available?

Our Heritage windows are available in virtually any RAL colour. The most popular choices are Black (RAL 9005) and Anthracite Grey (RAL 7016), which closely replicate the look of traditional steel. Dual-colour finishes are also available, allowing a different colour internally and externally to suit your interior scheme.

Can Heritage windows be used for internal glazing and partition screens?

Yes. Our Heritage systems are increasingly specified for internal applications such as crittall-style partition screens and room dividers. They create elegant, light-filled spaces and are well suited to open-plan homes, offices, and commercial environments where architectural character is as important as functionality.

What glazing options are available?

We offer a wide range of glazing options including clear, leaded, decorative, and obscure glass. High-performance double glazing is standard for thermal efficiency, and obscure glazing is available for bathrooms, utility rooms, and other areas requiring additional privacy.

Do Heritage windows require planning permission?

Replacing existing windows with Heritage aluminium systems does not usually require planning permission in standard residential properties, provided the appearance is similar to the original. However, listed buildings and properties within conservation areas may have additional restrictions. Our team can advise based on your specific project.

Heritage & Steel-Look Aluminium Windows

Heritage Windows

Authentic steel-look aesthetics combined with modern thermal efficiency

Designed to replicate the iconic Art Deco and Crittall-style steel windows. Our heritage range offers ultra-slim profiles, authentic design details, and A-rated energy efficiency.

For period properties, listed buildings, or contemporary homes seeking an industrial aesthetic, standard windows simply won’t do. Our Heritage Aluminium range is specifically engineered to replace old steel windows, maintaining the slender sightlines and elegant proportions of the original architecture while eliminating the drafts and condensation associated with single-glazed metal frames.

Manufactured in our Burntwood facility, these windows feature thermally broken aluminium profiles that are a fraction of the width of uPVC or timber. This allows us to create the classic “grid” look using authentic glazing bars, ensuring your home retains its charm and value.

Beyond the aesthetics, you gain all the benefits of modern engineering. Our heritage windows are secure, durable, and virtually maintenance-free. They effectively retain heat, significantly reducing your energy bills compared to the original steel frames, without compromising on the visual appeal.

Heritage Windows: Features

Authentic Steel-Look Design: Carefully engineered to replicate the appearance of traditional steel windows, our systems preserve the character of period and heritage properties while delivering the benefits of modern aluminium construction.
Ultra-Slim Sightlines: Featuring exceptionally narrow frame profiles that maximise glazed areas, allowing more natural light into the building whilst maintaining the elegant proportions associated with traditional steel windows.
A-Rated Thermal Efficiency: Advanced thermal break technology significantly reduces heat transfer, helping to improve energy efficiency, lower heating costs, and enhance occupant comfort.
Traditional Hardware Options: Available with a range of period-inspired ironmongery, including monkey-tail and bulb-end handles, providing an authentic heritage aesthetic without compromising functionality.
Discreet High-Security Locking: Integrated multi-point locking systems are concealed within the slim aluminium frame, delivering enhanced security while maintaining clean sightlines and traditional styling.
Versatile Opening Configurations: Available in a wide range of styles including fixed lights, side-hung casements, top-hung openings, and tilt-and-turn arrangements to suit both residential and commercial applications.
Heritage Appearance, Modern Performance: Combining classic aesthetics with contemporary manufacturing techniques, our steel-replacement windows offer exceptional durability, low maintenance requirements, and long-term performance.

Heritage Windows – Additional Details

Our Heritage window systems are available in virtually any RAL colour, allowing complete design flexibility to suit both traditional and contemporary properties. The most popular finishes are Black (RAL 9005) and Anthracite Grey (RAL 7016), which closely replicate the appearance of traditional steel windows and complement a wide range of architectural styles.

We offer a comprehensive selection of glazing options, including clear, leaded, decorative, and obscure glass, enabling homeowners and designers to achieve the desired balance of aesthetics, privacy, and performance. Obscure glazing is particularly well suited to bathrooms, utility rooms, and other areas where additional privacy is required.

Beyond external applications, our Heritage systems are increasingly specified for internal glazing and partition screens, creating elegant, light-filled spaces while maintaining separation between rooms. This makes them ideal for open-plan homes, offices, and commercial environments where natural light and architectural character are equally important.

Combining timeless aesthetics with modern performance, Heritage windows provide the perfect solution for renovation, conservation, and new-build projects seeking the distinctive look of traditional metal-framed glazing without the maintenance and thermal limitations of steel.
