For nearly a decade, RAL 7016: better known as Anthracite Grey: has been the undisputed heavyweight champion of the UK window and door industry. From sleek new builds in Windsor to renovated period properties in Beaconsfield, this versatile shade of grey became the default choice for homeowners seeking a modern, industrial aesthetic. It offered a sharp contrast to traditional white uPVC and provided a sophisticated finish that seemed to go with everything.

However, as we move through 2026, the architectural landscape is shifting. At Inspired Glazing, we are seeing a significant evolution in homeowner preferences. While Anthracite Grey remains a staple, it is no longer the only “modern” choice. Homeowners are increasingly looking for warmth, texture, and a more “organic” feel for their exteriors.

In this article, we explore whether Anthracite Grey is truly being dethroned and identify the emerging colour and texture trends that are defining double glazing and window installations this year.

The Rise and Longevity of Anthracite Grey

To understand where we are going, we must understand why Anthracite Grey became so dominant. Its popularity was driven by the rise of aluminium window systems and the desire for slim sightlines. The dark pigment of RAL 7016 works exceptionally well with aluminium, as it creates a receding effect that makes the frames appear even thinner, drawing the eye to the glass and the view beyond.

It also offered a practical solution: it hides dirt better than white or lighter shades and provides a high-end look without the price tag of bespoke metallic finishes. However, the sheer ubiquity of the colour has led some designers to label it as “overused.” In 2026, the trend is moving away from the “clinical” look of dark grey and white towards a palette that feels more grounded and connected to the environment.

The Emerging Contenders: 2026 Window Colour Trends

While grey isn’t disappearing, it is evolving. The “cool” blues and blacks of previous years are being replaced by “warm” neutrals and earth-inspired tones.

1. The “Mushroom” Neutral and Warm Greiges

The most significant challenger to Anthracite Grey in 2026 is the rise of mushroom and stone-based neutrals. These colours sit somewhere between grey and beige (“greige”) and offer a softer, more inviting appearance.

• Why it’s trending: These shades reflect a “mycology-inspired” palette that prioritizes natural, soothing tones.
• Visual impact: Unlike the starkness of Anthracite, mushroom tones blend seamlessly with stone cladding, traditional brickwork, and timber-framed extensions.
• Technical Benefit: Lighter shades like these have lower heat absorption rates compared to very dark greys, which can help in reducing thermal expansion in south-facing uPVC windows and doors.

2. Muted Bronzes and Metallic Earth Tones

For those who still want the “industrial” or “architectural” look of dark frames but want something more unique than standard grey, muted bronzes are the answer.

Anodised or powder-coated bronze finishes offer a metallic depth that changes with the sunlight. This trend is particularly popular in high-end projects in areas like Ascot and Sunningdale, where homeowners want their property to stand out with a premium, bespoke finish. Bronze provides a warmth that Anthracite lacks, making it a perfect partner for natural wood or landscaped gardens.

3. Sage Green and Earthy Neutrals

The “biophilic” design trend: bringing the outdoors in: has moved from interior paint choices to external glazing. Sage Green, Agate Grey, and Pebble Grey are becoming increasingly popular for bespoke energy-efficient windows.

These colours are less “aggressive” than black or dark grey. They provide a heritage feel that works perfectly for cottage-style homes or properties in conservation areas, while still looking crisp and modern on contemporary builds.

Texture: The Hidden Trend of 2026

It isn’t just the colour that is changing; it is the finish. In previous years, a smooth, matte finish was the standard for Anthracite Grey. In 2026, texture is taking centre stage.

• Woodgrain Foils on Aluminium: We are seeing an increase in aluminium systems finished with high-quality woodgrain foils that mimic the texture of oak or walnut.
• Sand-Blasted Finishes: A textured, grainy finish provides a tactile quality to the window frame. It reduces glare and gives the colour a more “matte-plus” appearance that looks more like natural stone or cast iron.
• Metallic Fleck: Subtle metallic inclusions in the powder coating help the frames catch the light, preventing large expanses of dark colour from looking “flat” or “lifeless.”

Material Showdown: How Colour Affects Choice

When choosing your window colour, the material of the frame plays a vital role in the final look and the longevity of the finish.

Aluminium Windows

Aluminium is the preferred material for bolder, modern colours. The powder-coating process used for aluminium windows is incredibly durable and allows for almost any RAL colour. If you are looking for those emerging bronze or deep jewel tones, aluminium offers the most precise and high-quality finish. You can explore our range of aluminium windows and doors in Ascot and Sunningdale to see how these finishes look in person.

uPVC Windows

Modern uPVC has come a long way from the “plastic” look of the 90s. High-quality foils allow uPVC windows to mimic the look of Anthracite Grey or the new “mushroom” tones perfectly. For homeowners looking for a cost-effective way to update their home’s aesthetic without sacrificing thermal performance, uPVC remains an excellent choice. Our guide on aluminium vs uPVC windows provides a deeper dive into which material might suit your specific project goals.

Performance and Longevity: A Technical View

At Inspired Glazing, we don’t just focus on aesthetics; we focus on long-term performance. When moving away from the “safe” choice of Anthracite Grey, there are technical factors to consider:

1. UV Resistance: Darker colours absorb more heat. In the height of summer, a dark frame can reach high temperatures, which may cause slight expansion. High-quality powder coating and multi-chambered profiles are essential to ensure the window remains weather-tight.
2. Colour Matching: If you choose a niche trend colour, ensure your installer can provide matching composite doors or roofline products. A mismatched front door can ruin the cohesive look of a renovation.
3. Maintenance: While Anthracite is great at hiding dirt, the new “earthy” neutrals like Sage or Stone require slightly more frequent cleaning to maintain their “fresh” appearance. However, the smooth, high-grade finishes we provide make this a simple task of a wipe-down with soapy water.

Case Study: From Grey to “Warm Stone” in Beaconsfield

Challenge: A client in Beaconsfield felt their home looked too “cold” with its existing white uPVC windows but didn’t want the standard “industrial” look of Anthracite Grey that many of their neighbours had recently installed.

Solution: We recommended a slimline aluminium system finished in a Warm Stone (RAL 7032) with a textured matte finish. This provided the modern, slim sightlines the client wanted while softening the overall exterior of the red-brick property.

Result: The property gained a unique, sophisticated look that increased curb appeal significantly. The “Warm Stone” frames perfectly complemented the new timber front door, creating a harmonious and welcoming entrance. You can see similar transformations in our case studies section.

Is Anthracite Grey Dead?

The short answer is: No. Anthracite Grey is not “dead,” but it is no longer the default. It has transitioned from being a “trend” to being a “classic.” Much like white or black, it will always have a place in home design because of its reliability and versatility.

However, if you want your home to reflect the cutting edge of 2026 design, you should look towards warmer, more organic palettes. The move towards bronzes, muted greens, and “mushroom” neutrals reflects a broader desire to make our homes feel like sanctuaries: spaces that are warm, grounded, and unique.
