What are alu-clad windows?
Alu-clad windows combine engineered timber frames with powder-coated aluminium exterior cladding.
This composite construction was originally developed to extend the lifespan of traditional timber windows. Today's alu-clad designs offer far more than improved longevity – they represent a complete rethinking of window performance for modern UK homes.
Sustainably sourced timber interior provides exceptional natural insulation and creates warm, inviting living spaces. External aluminium cladding shields the timber from harsh weather, eliminates the need for regular external painting, and allows for contemporary design flexibility with any RAL colour finish.
Performance advantages that transform your home
If you're looking for windows that combine exceptional performance with minimal maintenance, alu-clad designs deliver exactly that. The sophisticated blend of natural timber and protective aluminium creates a solution that performs brilliantly for decades.

Maintenance & Weather Resistance
Britain's variable climate demands windows that can withstand persistent rain, strong winds, and temperature fluctuations.
The aluminium exterior provides robust protection against these elements, maintaining its appearance and performance year after year.
Unlike timber windows that require regular external maintenance, alu-clad designs remain virtually maintenance-free. A simple wash with soapy water keeps the powder-coated aluminium looking pristine. This represents significant time and cost savings over the window's lifetime.
Thermal Efficiency
The combination of timber and aluminium delivers remarkable insulation performance.
Wood has inherently low thermal conductivity – approximately 800 times more effective as an insulator than aluminium alone.
When you choose triple glazing within alu-clad frames, you achieve exceptional whole-window U-values – as low as 0.64. This translates directly into warmer rooms, reduced heating bills, and enhanced comfort throughout the year.
The deep frame profiles possible with alu-clad construction accommodate advanced glazing specifications.
The practical result? Stable interior temperatures, reduced condensation risk, and lower heating costs – particularly significant as energy prices fluctuate.
Sustainability Credentials
Made predominantly from timber, the manufacturing processes and waste materials of alu-clad windows are more environmentally friendly than those used for all aluminium or UPVC windows.
The sawdust produced from the production of our timber window frames, for example, is used to heat the factory. Additionally, the improved thermal efficiency of alu-clad windows can significantly contribute to a reduction in your home’s CO2 emissions and your heating bill.
Alu-clad windows align naturally with environmentally conscious building practices. The predominant use of timber – a renewable, carbon-storing material – gives these windows a significantly lower embodied carbon footprint compared to all-aluminium or uPVC alternatives.
We use production waste efficiently. Sawdust from timber processing heats our factory, while offcuts are repurposed. FSC certification ensures forests are managed sustainably, with replanting maintaining long-term timber supplies.
The exceptional thermal performance of alu-clad windows contributes directly to reducing your home's operational carbon emissions. Lower heating demand means less energy consumption, delivering environmental benefits alongside lower utility bills.
For projects targeting Passive House certification or other stringent energy standards, alu-clad windows provide the performance credentials required whilst maintaining design flexibility.
Design Flexibility
Contemporary alu-clad windows offer remarkable customisation options. The aluminium exterior can be finished in any RAL colour, allowing you to perfectly complement your home's architectural style.
Dual-colour finishing presents intriguing possibilities. You might select a bold, contemporary colour externally – perhaps anthracite grey or bronze – whilst choosing a softer tone internally that harmonises with your interior design scheme.
The timber interior can be factory-finished with paint, or treated with translucent stains that showcase the natural wood grain. Many homeowners appreciate this ability to enjoy the warmth and authenticity of real wood inside their homes, whilst benefiting from the sleek, modern aesthetic of aluminium on the exterior.
Frame profiles range from traditional to ultra-contemporary. Slimmer sightlines create a minimalist appearance that maximises glazed area and natural light. Alternatively, deeper frames with decorative mouldings suit heritage properties or renovations where traditional character matters.
Enduring Value
HIgh quality alu-clad windows represent a long-term investment in your home's comfort and value. With proper installation and minimal maintenance, these windows perform reliably for 40-60 years.
Compare this to UPVC windows (20-25 year lifespan) or lower-quality alternatives requiring replacement far sooner, and the lifetime value proposition becomes clear.
Properties with high-performance windows also command premium resale values, as prospective buyers increasingly prioritise energy efficiency and low maintenance requirements. Our customers consistently rate their experience highly, reflecting the long-term satisfaction that comes from choosing quality products backed by genuine care and expertise.

Your Questions Answered
Have a question? You're not alone. We've answered some of the most common questions about Alu-Clad Windows below, drawing from years of expertise helping homeowners and professionals achieve their vision.
Collapsible content
What are alu-clad windows?
Alu-clad timber windows are made from engineered timber clad externally in powder-coated aluminium cladding.
These windows combine the excellent insulation properties, durability and charm of timber with the low maintenance needs of aluminium. As a result, they are some of the most attractive and best quality products on the market.
Are alu-clad windows expensive?
Alu-clad windows tend to be more expensive than all timber versions and uPVC models.
They offer a wider range of benefits including better thermal performance, aesthetic appeal, a longer lifespan, use of more environmentally friendly materials and lower maintenance. They are certainly the smarter choice for a well-insulated home in the long run.
What are the benefits of alu-clad windows?
Aluminium clad windows are durable and provide excellent insulation thanks to the timber frames.
The aluminium cladding protects the window from weather damage and decay, ensuring a long lifespan of low-maintenance, dependable performance. As a result, they are some of the most attractive and best quality products on the market.
Are alu-clad windows suitable for damp UK climates?
Absolutely. Modern alu-clad windows are specifically engineered for challenging weather conditions.
The aluminium cladding creates an impermeable barrier against rain and moisture, whilst sophisticated drainage systems prevent water accumulation. For coastal properties, marine-grade aluminium options provide exceptional corrosion resistance. These design advances make alu-clad windows ideal for the UK's variable climate.
Can alu-clad windows be painted?
Our aluminium-clad windows can be finished in any RAL colour with a powder-coated finish.
Dual colour finish - different colours inside and out - is available as standard, so there is no shortage of options when choosing the colour of your windows! Internally the windows can be repainted later if desired.
How do alu-clad windows compare to uPVC?
Alu-clad windows deliver superior thermal performance, thanks to timber's excellent insulating properties. They last significantly longer – 45+ years versus 20-35 years for uPVC.
The environmental footprint is lower due to renewable timber and efficient manufacturing. Aesthetically, alu-clad windows offer greater customisation and the authentic appeal of real wood internally. Whilst initial costs are higher, long-term value strongly favours alu-clad specification.
Are alu-clad windows better than wood windows?
Aluminium-clad timber windows provide all the same benefits as wood windows - exceptional thermal performance, charming interior style, durability - with the extra benefit of being more weather resistant thanks to the protective layer of aluminium.
However, if traditional style is first priority then wooden window frames provide a more classic look.
Do modern alu-clad windows still suffer from rot issues?
No. Historical rot problems that affected earlier window designs have been comprehensively solved.
Today's alu-clad windows feature protective base coatings on timber before cladding installation and engineered drainage to channel water away from wood components. The result is exceptional durability with expected lifespans exceeding 45 years.
Are alu-clad better than aluminium windows?
While aluminium frames are strong and light, aluminium is a very poor insulating material - over 1000 times worse than wood.
Even with multi-chambered extrusions and thermal breaks, aluminium still performs much more poorly than timber as a frame material. Aluminium also has higher environmental impacts and higher embodied carbon.
Can alu-clad windows achieve Passive House standards?
Yes. High-quality alu-clad windows readily meet or exceed Passive House certification requirements.
With appropriate specification – typically including triple glazing, low U-value frames, and careful detailing – these windows deliver the exceptional thermal performance Passive House projects demand. We provide PHPP (Passive House Planning Package) data to support certification applications.
Making the right choice for your project
Alu-clad windows typically cost more than UPVC alternatives but less than premium all-timber options. However, focusing solely on initial outlay misses the fuller picture.
Consider total lifetime costs: no external repainting, decades-longer lifespan, superior thermal performance reducing energy bills, and enhanced property value. The mathematics increasingly favour quality alu-clad windows, particularly for homeowners planning to remain in their property long-term or seeking to maximise resale appeal.
Specification Considerations
-
Timber Quality
Look for FSC-certified timber with preservative treatment specifications. This ensures your windows use sustainably sourced wood that's been properly protected.
-
Glazing Specification
Double glazed windows suit moderate climates, whilst triple glazing delivers optimal performance for passive house windows standards or homes prioritising maximum comfort.
-
Installation Expertise
Even the finest windows underperform when poorly installed. Seek installers with specific alu-clad experience.
