When it comes to aluminium windows, the system, hardware, and performance matter, but so does the finish. RAL colours for aluminium windows have become a key decision point for both architects and homeowners, shaping the final look of façades, interiors, and entire projects.
At GREFET, we supply powder-coated aluminium systems in over 450 RAL colours, a palette that evolves every year. In 2025, we’re seeing clear shifts in colour preferences across residential, commercial, and institutional buildings. This isn’t just about aesthetics; it’s about matching performance with personality, identity with durability.
Let’s break down what’s trending this year and what to keep in mind when choosing RAL finishes for aluminium windows.
Earthy Neutrals are in: The Rise of Warm Grey, Clay, and Sandstone
While jet black (RAL 9005) and white (RAL 9016) still dominate in volume, neutral earth tones are gaining serious ground in 2025. Think RAL 7039 (Quartz Grey), RAL 1019 (Grey Beige), and RAL 7032 (Pebble Grey).
Why the shift? These tones work brilliantly with exposed concrete, stone cladding, and wooden finishes. They create softer, warmer façades without compromising modern minimalism. For villas, farmhouses, and boutique hotels, these colours offer a subtle sophistication that’s hard to beat.
Matte Black is Still King, but Now with Texture
RAL 9005 (Jet Black) and RAL 9004 (Signal Black) remain favourites, but not in gloss. What’s trending in 2025 is matte and textured finishes. Powder coating technology now allows for grit matte blacks, sand-finish blacks, and fine-textured options that hide fingerprints and look more premium.
If you’re designing ultra-modern bungalows or commercial buildings with glass façades, this finish gives an edge — literally and visually.
Bolder Architectural Colours: Deep Blues, Forest Greens & Burnt Reds
Minimalism isn’t the only story in 2025. There’s a growing movement, especially in premium architecture, to reintroduce bold colours to aluminium systems. The most requested shades include:
- RAL 6009 (Fir Green)
- RAL 5003 (Sapphire Blue)
- RAL 8012 (Red Brown)
These aren’t loud primary colours. They’re deep, muted tones that offer character without overwhelming the structure. They’re especially popular in urban restoration projects, luxury villas, and architect-led residences.
Stainless Steel Look: When You Want the Look Without the Cost
One of the most asked-for finishes at GREFET continues to be the stainless steel look on aluminium profiles. While technically not a RAL shade, this metallic finish mimics the elegance of steel, without the weight or price.
It’s ideal for high-rise commercial projects, public infrastructure, and clients who want a sophisticated, modern appearance without compromising on performance.
Things to Keep in Mind When Choosing RAL Colours for Aluminium Windows
1. Consider the climate:
Lighter shades reflect more heat, which can help in warmer regions like Rajasthan or Telangana. Darker colours absorb more heat and can expand more, especially in intense sun.
2. Think long term:
Trends evolve, but windows last decades. Neutral greys and deeper tones tend to age better than very light or flashy colours.
3. Coordinate with other materials:
Look at your cladding, paint, flooring, and hardware. Your aluminium window colour should either blend seamlessly — or contrast intentionally.
4. Always go with powder coating over wet paint:
At GREFET, we only use high-quality powder coating that ensures UV stability, scratch resistance, and colour fastness for years to come.
GREFET Gives You the Freedom to Choose
The truth is, RAL colours for aluminium windows aren’t just cosmetic — they’re strategic. They impact curb appeal, temperature regulation, and even perceived value. In 2025, you don’t need to settle for standard shades. GREFET offers anodised, textured, and powder-coated finishes in over 450 RAL colours, custom-matched to your project.
