Thinking about upgrading your home’s windows? If you live in Mill Hill, NW7, and love modern design with a touch of industrial charm, you’ve likely seen Crittall-style windows. These stunning windows are famous for their slim black frames and grid patterns. They let in loads of natural light and make a bold style statement.
At Dev Enterprise, we help homeowners across NW7 find the perfect windows. We know you might have questions. Are they efficient? Are they expensive? Can you get a similar look with aluminium? This blog answers all your questions about Crittall-style windows and their popular alternatives.
What Exactly Are Crittall-Style Windows?
Crittall-style windows take their name from the original Crittall-style Windows company. This company was a pioneer in making steel-framed windows over a century ago. Today, the “style” refers to windows that capture that same iconic look.
The key features include:
- Very slim frames: The metal framework is minimal, so you see more glass and less frame.
- Grid patterns: They often feature black grids, creating a dramatic industrial feel.
- Strength and elegance: Originally made from steel, they are both strong and beautiful.
This style is perfect for both period homes and new builds in Mill Hill, adding unique character and value.
Crittall-Style vs. Aluminium Alternatives: What’s the Difference?
While genuine Crittall-style windows are made from steel, most homeowners today choose aluminium alternatives. Here’s a simple comparison to help you decide:
- Genuine Steel Windows: Made from steel. They are incredibly strong and have the slimmest possible frames. However, they can be heavier, require more maintenance to prevent rust, and are often more expensive.
- Aluminium Alternatives: Made from aluminium. They are designed to look exactly like steel but are lighter, rust-proof, and need very little upkeep. Modern systems like the Alitherm Heritage offer fantastic thermal efficiency, which is a key advantage.
For most homes in Mill Hill, aluminium Crittall-inspired windows offer the best balance of looks, performance, and value.
Are Crittall Look Windows Energy Efficient?
Yes, absolutely! Old-fashioned steel windows were draughty. But modern Crittall-style windows, especially aluminium ones, are built for efficiency.
High-quality aluminium alternatives include features like:
- Thermal break technology: A special barrier inside the frame that stops heat from escaping.
- Double glazing: Standard for excellent insulation and noise reduction.
- Weather seals: Keep the cold wind and rain out of your NW7 home.
This means you can enjoy the beautiful industrial look without worrying about high energy bills.
How Expensive Are Crittall-Style Windows?
The cost can vary a lot. Genuine steel-framed windows are a premium product with a higher price tag. Steel-look aluminium windows and doors are a more affordable option that gives you the same aesthetic.
As a rough guide:
- Original steel windows are a significant investment, often costing thousands per window.
- Aluminium Crittall-inspired windows are more budget-friendly, offering similar style at a lower cost.
At Dev Enterprise in Mill Hill, we provide clear quotes and options to suit different budgets. We help you get the look you want without surprise costs.
Can I Get Them in Different Colours?
Of course! While classic black is the most popular choice for that authentic industrial-style window look, you are not limited. Modern windows can be powder-coated in almost any colour you can imagine.
Popular choices include:
- Dark Grey: A softer alternative to black.
- White: For a cleaner, more modern look.
- Metallic Finishes: Like graphite or anthracite grey.
- Dual-Colour: You can even have one colour on the outside (e.g., black to match the house) and another on the inside (e.g., white to match your decor).
What Are the Best Aluminium Alternatives?
For homeowners in NW7, one of the best systems available is the Alitherm Heritage aluminium windows system. It is specifically designed to replicate the Crittall-look with performance in mind. Its key benefits include:
- Authentically slim frames that look like steel.
- Superior thermal efficiency to keep your home cosy.
- Strong and durable construction built to last.
- A wide range of customisation options.
Dev Enterprise often recommends this system for its outstanding quality and authentic appearance.
What is the Alitherm Heritage System?
The Alitherm Heritage system is a high-performance aluminium window system. It is engineered to create the elegant look of traditional heritage steel windows but with modern benefits. It uses a thermal barrier to prevent heat loss and can be fitted with double glazing. This makes it an ideal choice for conservation areas or any home in Mill Hill where style and efficiency are important.
What Are Steel-Framed Aluminium Windows?
This term can be confusing! Steel-framed aluminium windows are actually aluminium windows made to look like steel. You get the stunning visual appeal of slimline metal windows without the potential drawbacks of real steel, like rust or high maintenance. They are a practical and beautiful solution for any property.
What Are Crittall Look Interior Screens?
It’s not just about windows! The Crittall-look is also popular for interior uses. Crittall-look interior screens are metal-framed partitions or room dividers. They are perfect for:
- Defining a space in an open-plan living area.
- Creating a stylish entrance hall screen.
- Enclosing a shower area in a bathroom while still letting light through.
They add architectural interest and a modern, industrial vibe to your home’s interior.
Are They Available with Double Glazing?
Yes, definitely. In fact, double glazing is standard for quality aluminium Crittall-inspired windows. For homes in Mill Hill, which can be near busy roads or exposed to weather, double glazing provides essential insulation against both cold and noise. Some manufacturers even offer triple glazing for ultimate performance.
