Hi there, Tomek from Wingedas here. I've been on installation sites for 18 years, and I can tell you outright – choosing window colours is one of the toughest decisions for investors today. Just 10 years ago, white reigned supreme, and "golden oak" was the height of extravagance. Today, two contenders are battling it out: deep, matte black and the versatile, elegant anthracite. Clients constantly ask: "Mr. Tomek, which is better? Which will be fashionable in 5 years? Which won't I regret?"
Last week, we were installing windows on a new estate near Warsaw. Two identical houses side by side. One with jet-black frames, the other with classic RAL 7016 anthracite. The result? Two completely different buildings. This shows the immense power of what seems like a simple choice. That's why I decided to compile my experiences from hundreds of installations and write this article. No sugar-coating, no marketing jargon. Just practical insights and facts from the construction site. Let's get started.
Black windows – a bold style statement
I'll be frank: black windows are a choice for the daring. When I arrive on a construction site and see openings prepared for black frames, I immediately know the investor has a clear vision. This isn't a coincidence. Black is a definitive colour that shapes the character of a building. It perfectly suits modern "barn houses", lofts, homes with simple forms and minimalist details. From my observations, 8 out of 10 clients choosing black already have a black roof, black gutters, and often black elements in their fencing design.
I remember a client from Konstancin who built a house entirely in white with black joinery and a black roof. The effect was straight out of an architectural magazine. But I also remember another who tried to combine black windows with a brown roof and a sandy-coloured facade. It looked, to put it mildly, not great. Black is unforgiving.
Advantages of black windows:
- The "WOW" factor: No one will pass by such a house indifferently. Black frames beautifully frame the view from the inside.
- Modernity: This is the epitome of modern design. If you're aiming for an industrial or minimalist style, black is a perfect choice.
- Complements wood exceptionally well: The combination of black with natural, light wood on the facade is a duo that looks stunning.
Disadvantages of black windows (rarely talked about):
- Every speck is visible: Dust, sand, rain streaks – everything is visible on a black, especially matte, surface. Clients are often surprised by this after the first month of use.
- Heat absorption: This is the biggest flaw of black profiles. On a sunny day, they can heat up to 70-80°C. This causes stress in the material and can lead to adjustment issues. I'll elaborate on this shortly.
- More challenging to style: Black is dominant. It's harder to match the facade colour, and indoors, it can be overwhelming if rooms are small and poorly lit.
Anthracite windows – the master of versatility
Anthracite, specifically RAL 7016, has been the absolute king in recent years. Statistics from our installations in 2024-2025 show that this colour accounted for over 60% of window orders in colours other than white. Why such popularity? Anthracite is a chameleon. It's dark and elegant like black, but it has grey undertones that make it far more versatile.
I've seen anthracite windows in modern barn houses, classic manors, homes with pitched roofs, and in big-city apartment blocks. It fits everywhere. It pairs excellently with white, greys, graphite, but also with warm beige or brick. It's not as radical as black, making it simply a safer long-term choice.
Advantages of anthracite windows:
- Versatility: They suit almost any style and facade colour. This is their greatest strength.
- Elegance and timelessness: Anthracite is fashionable today and will be fashionable in 10 years. It's a colour that doesn't age.
- Practicality: Dirt is far less visible on it than on black. It's easier to keep clean.
- Less heat absorption: Although it's still a dark colour, it heats up noticeably less than black, which translates into profile stability.
Disadvantages of anthracite windows:
- "Boring" for some: For those seeking something truly distinctive, anthracite might seem too obvious and commonplace. Sometimes I hear from clients: "Everyone has it."
- Still requires discipline: Although versatile, it still needs to be well-coordinated with the roof and gutters to avoid visual chaos.
Black vs. Anthracite: A direct showdown
To help you make a decision, I've prepared a simple comparison table. I've gathered the most important criteria that my clients consider when choosing. This is the essence of my 18 years of experience.
| Criterion | Black Windows (e.g., RAL 9005) | Anthracite Windows (e.g., RAL 7016) |
|---|---|---|
| Aesthetics and Style | Ultra-modern, loft-style, minimalist. A very strong accent. | Elegant, versatile, timeless. Suits many styles. |
| Practicality (cleaning) | Very low. Every speck of dust and raindrop is visible. | Good. Conceals minor dirt much better than black. |
| Heat Absorption from Sun | Very high. Risk of distortion and adjustment problems. | High, but noticeably lower than black. The profile is more stable. |
| Matching Facade and Roof | Demanding. Looks best in monochromatic combinations (white, grey, black). | Very easy. Coordinates well with most render colours, wood, and roof tiles. |
| Visibility of Scratches | High. Every scratch, even minor, will be more visible on the veneer. | Medium. The texture and colour better conceal small damages. |
| Perception in 10 Years | May become "out of fashion" if the trend passes. A risky choice. | Likely to still be considered elegant and contemporary. A safe choice. |
| Price | Typically in the same price group as anthracite from most manufacturers. | Standard in the offer, often without surcharges compared to other popular colours. |
Practical problems with dark windows that sellers won't tell you about
In showrooms, you'll mainly hear about aesthetic benefits. I'll tell you what we really struggle with during installations and servicing. Here are the industry secrets:
- Bimetallic effect: This is the most significant problem, especially with black windows. The outer side of the profile, heated by the sun, expands much more than the inner side, which remains at room temperature. The sash literally bows. Good windows have special reinforcements and are designed with this phenomenon in mind, but with cheaper profiles, this leads to leaks and constant problems with closing. I've seen it dozens of times.
- Veneer quality is crucial: A salesperson will say "anthracite colour". I'll ask: "what film?" There are many cheap veneers on the market that, after 5-7 years in the sun, start to fade, and corners can delaminate. Reputable manufacturers, such as Veka, Salamander or Schüco, use high-quality films (e.g., Hornschuch, Renolit) with technologies protecting against overheating (e.g., Cool Colors). ALWAYS ask about the manufacturer and technology of the film. This is more important than the profile name.
- Installation must be perfect: Dark, heavy triple-glazed units in large frames are unforgiving of installation errors. The window must be perfectly level and securely anchored. Any stresses in the wall, transferred to the frame, combined with the thermal expansion of the dark colour, are asking for trouble. That's why "warm installation" (warm fitting) using vapour-proof and vapour-permeable tapes, which creates a flexible and airtight connection with the wall, is so important.
Which colour suits your home? My advice as an installer
Unsure what to choose? I'll give you a simple test and some advice I use when advising clients on site.
- Look at the roof: This is the largest colour surface apart from the facade. If you already have a graphite or anthracite roof, windows in the same colour will be a safe and coherent choice. If the roof is black, black windows can create a beautiful, graphic duo. Avoid combining black windows with a brown or red roof.
- Think about the interior: Stand in the living room and imagine the view outside the window. A black frame strongly "frames" it, drawing attention. An anthracite frame is more neutral. If you have small rooms, a black frame might optically make them appear slightly smaller and more oppressive.
- Order samples and take them outside! Never, ever choose a colour from a catalogue under artificial showroom lighting. Ask for a physical veneer sample. Place it against the facade, against a roof tile, view it in full sun and in shade. You'll be surprised how much the same colour can change depending on the environment and light.
- Be realistic about cleanliness: If your home is near a dusty road, a construction site, or you simply don't like cleaning windows constantly, forgo matte black. You'll save yourself a lot of stress. Anthracite with a wood-effect or sandblasted texture will be much more practical.
Conclusion: My verdict – black or anthracite?
After 18 years in this industry and thousands of installed windows, I have my opinion. If I were building my own home today and had to choose between these two colours, 90% of the time I would choose RAL 7016 anthracite. Why? Because it's a wise, safe, and timeless choice. It's elegance that won't age and won't cause operational problems. It's a colour that offers enormous design freedom and is more forgiving.
Black windows are like a red Ferrari. They make a stunning impression, catch the eye, but they are demanding, impractical for everyday use, and not for everyone. If you're ready for compromises in the name of spectacular design and have a precise vision for your home – go for black. But if you're looking for a happy medium between great looks, functionality, and peace of mind for years to come – anthracite will be your best friend.
Remember, windows are an investment for 20-30 years. Trends come and go, but a well-chosen, functional product will serve you and delight your eye for decades. Choose wisely!

Anthracite windows: potential drawbacks and what to consider
Choosing anthracite-coloured windows is a decision that can transform the character of any facade, giving it a modern and elegant look. However, like any building product, anthracite windows have certain aspects that deserve particular attention before making a final decision. From our perspective, as experts with many years of experience in the window industry, a conscious approach to their operation and potential challenges is key. While the aesthetic advantages are undeniable, there are some disadvantages of anthracite windows that can impact comfort and long-term satisfaction.
One of the most frequently discussed issues when it comes to anthracite windows is their tendency to absorb heat. Dark surfaces absorb more sunlight, which on hot days can lead to an increase in indoor temperatures, especially for windows with south or west exposure. This is a significant disadvantage of anthracite windows that should be considered when planning a ventilation system or choosing appropriate sun blinds. Furthermore, dust, pollen, and rain streaks are more easily visible on darker frames, which may require more frequent and thorough cleaning to ensure the windows always look impeccable.
Another potential disadvantage of anthracite windows, though less common, is the possibility of visible scratches or mechanical damage. On a dark surface, even minor scratches can be more noticeable than on lighter profiles. Therefore, during installation and subsequent use, we recommend particular care. Despite these potential inconveniences, proper care of anthracite windows and a conscious approach to their specifics will allow you to enjoy their unparalleled aesthetics for many years, without disappointment.
- Profiles heating up in intense sunlight.
- Increased visibility of dust and dirt.
- Potentially more visible scratches.
- Requirement for more meticulous maintenance and cleaning.
