Key findings

• Superior durability: Aluminium windows offer exceptional longevity with 25-year guarantees against peeling, warping and bowing, making them perfect for modern properties that demand long-term performance.
• Outstanding energy efficiency: Modern aluminium windows achieve A-rated thermal performance through advanced thermal break technology, helping homeowners reduce energy bills whilst meeting current building regulations.
• Unmatched design flexibility: With over 200 RAL colour options and slim sightlines, aluminium frames provide clean lines that complement contemporary architecture whilst maximising natural light intake.
• Low maintenance requirements: Unlike timber frames that require regular upkeep, aluminium windows need only occasional cleaning with warm soapy water, making them the perfect choice for busy modern lifestyles.
• Excellent security standards: Multi-point locking systems and PAS 24 accreditation provide superior home security, giving homeowners peace of mind in today’s security-conscious world.

When it comes to window materials for modern homes, aluminium stands head and shoulders above the rest. This versatile metal has revolutionised contemporary design, offering homeowners the perfect combination of style, performance and practicality that today’s properties demand.

Modern aluminium windows have shed their old reputation for poor thermal efficiency. Today’s advanced thermal break technology transforms aluminium window frames into high-performing window solutions that rival any material on the market. From sleek urban apartments to sprawling garden rooms, aluminium windows provide the clean lines and low maintenance that complement contemporary lifestyles.

At Warwick Development, we’ve been perfecting aluminium window solutions for over 30 years from our Sheffield headquarters. Our comprehensive range includes everything from heritage-style windows for period property renovations to ultra-modern flush casement windows for new window installations (you’ll notice how the window frame sits perfectly level with the glass!) With our expert team’s knowledge and cutting-edge manufacturing facility, we’re helping homeowners discover the benefits of aluminium windows and why they’re the smart choice for modern living.

Aluminium windows are an excellent choice for a modern aesthetic

An introduction to aluminium windows

Aluminium is one of the most abundant metals on Earth, making up approximately 8% of the planet’s crust. This lightweight yet incredibly strong material has become a cornerstone of modern construction, particularly in window frame manufacturing where its unique properties shine brightest.

As window frames go, aluminium offers exceptional structural integrity. Its strength-to-weight ratio is remarkable – aluminium is roughly three times lighter than steel yet maintains incredible durability. This combination of strength allows for larger glass areas and slim frames without compromising on performance, making it ideal for contemporary design trends that prioritise natural light and open spaces.

From an environmental perspective, aluminium is highly sustainable. It’s 100% recyclable without losing its properties, and recycled aluminium requires 95% less energy to produce than new aluminium. This makes modern aluminium windows an environmentally conscious choice for sustainability-minded homeowners looking to reduce their carbon footprint whilst enjoying the benefits of aluminium windows.

Aluminium windows have thermal break technology to reduce heat transfer.

What makes aluminium ideal for modern homes?

Modern homes demand window solutions that match their architectural vision whilst delivering exceptional performance. Aluminium windows tick every box, providing the perfect window style for contemporary living and offering a good reason to consider them for your home improvement project.

Exceptional strength for maximum natural light

The inherent strength of aluminium window frames means we can create windows with much slimmer sightlines than wooden windows or uPVC frames. This structural advantage allows for larger glass areas, flooding modern interiors with natural light and fresh air whilst maintaining the clean lines that contemporary design demands. Where timber might require bulky reinforcement, aluminium achieves superior strength with minimal visual impact.

Outstanding thermal efficiency

Gone are the days when aluminium meant poor insulation. Modern aluminium windows incorporate sophisticated thermal break technology, creating a barrier between interior and exterior sections. This innovation allows our aluminium casement windows to achieve A-rated energy efficiency, helping homeowners reduce heating costs whilst meeting building regulations requirements.

Built to last with real visual appeal

Aluminium windows are genuinely durable. We’ve seen aluminium windows we installed 20 years ago still looking excellent, whilst wooden windows from the same era are showing their age with peeling paint and warped frames. There’s a good reason we can offer that 25-year guarantee against peeling, warping and bowing, we’ve watched these windows perform consistently year after year.

Wooden windows look lovely when new, but they require constant attention. Aluminium windows maintain their appearance and structural integrity without the ongoing maintenance headaches.

Forget about weekend window maintenance

With aluminium windows, your maintenance routine consists of occasional cleaning with warm soapy water. That’s genuinely all that’s required. No scraping paint, no annual treatments, no concerns about wood rot or weather damage.

This low maintenance approach fits perfectly with busy modern lifestyles. As much as we love windows and all things home improvements, we’re well aware that the last thing people want to do on their weekend is routine maintenance!

Your home, your style, your colours

Every property we work on has different requirements. Whether you’re planning sleek anthracite grey on a contemporary build or a bronze finish on a period conversion, our 200+ RAL colour options provide genuine flexibility. The powder coating process ensures these colours remain vibrant for decades.

We’ve worked on projects ranging from artist studios with bold red windows to subtle wood-grain effects that closely resemble timber. This variety of colours means you can achieve exactly the aesthetic you want, whether for garden rooms that blend with the surroundings or statement windows that define your property’s character.

Aluminium windows from Warwick Development

From our Sheffield facility, we’ve been manufacturing windows for over 30 years. Our manufacturing approach focuses on precision and quality rather than mass production – we’re making windows that fit your specific requirements.

Our guarantees reflect our confidence in the product: 25 years against manufacturing defects, 10 years on sealed units, with every installation FENSA registered. We maintain these standards because we know what our manufacturing process can deliver.

The initial cost of aluminium windows is higher than some alternatives, but when you calculate maintenance costs over 20 years with other materials, aluminium windows represent genuine long-term value. Factor in the energy savings from A-rated thermal performance, and the economics become even clearer.

Alitherm contemporary windows

The Alitherm 800 system is our contemporary solution for homeowners wanting maximum glass area with slim profiles. This means more natural light entering your property. For properties near busy roads, we can specify these with acoustic glass that significantly reduces noise transmission.

Heritage aluminium windows

Our Heritage 47 system addresses planning requirements where modern performance must be combined with traditional steel window aesthetics. We’ve successfully used these on listed building projects where conservation requirements are strict. They achieve Window Energy Rating B whilst maintaining authentic appearance.

Flush casement windows

The Alitherm 400 flush system creates clean architectural lines that define contemporary design. With U-values reaching 1.4 W/m²K, thermal performance matches aesthetic appeal.

We also manufacture aluminium doors including bifold doors and entrance doors that coordinate perfectly with your window installation, creating visual consistency throughout your property.

Are aluminium windows energy efficient?

Modern aluminium windows with thermal breaks achieve A-rated performance that equals any other window material currently available. Thermal break technology eliminated the historical thermal bridging issues completely.
