HOW LONG DO ALUMINIUM WINDOW FRAMES LAST?
Aluminium has quietly become the hallmark of modern home design – sleek, strong and built to last. From minimalist frames to flawless finishes, it’s combined and redefined what longevity and luxury look like.
As we continue to invest in sustainable, energy-efficient upgrades, aluminium has moved firmly into the spotlight – not just for its strength and style, but for how well it performs over time. In an era where energy costs and design expectations are rising side by side, it’s a material that delivers both reassurance and refinement.
The question isn’t how long aluminium window frames last – it’s why they last so well. Here’s what makes aluminium one of the most dependable choices for modern homes.
Built to last – and stay looking sharp
Well-made aluminium window frames can easily last 40 years or more. Aluminium is strong, stable and naturally resistant to the issues that shorten the life of other materials. It won’t warp, swell or crack when exposed to moisture, and it doesn’t fade or become brittle in sunlight.
Its rigidity allows for slimmer profiles – meaning more glass, more light and cleaner lines that enhance both the interior and exterior of your home. That strength and precision are what define SILKA Aluminium Windows’ signature look: minimalist design that feels solid, secure and built to last.
SILKA aluminium window frames are finished with our smooth-as-SILKA fine textured surface – a tactile, matte coating called SILKtouch. The finish is soft to the touch yet incredibly durable, designed to resist fingerprints, everyday marks and fading while maintaining its consistent, quality appearance.
Low maintenance, high reward
Durability of course only counts if it’s effortless to maintain. One of the biggest advantages of aluminium window frames is how little attention they need. A quick clean with mild soapy water every few months is usually enough to keep SILKA Aluminium Windows looking their best.
There’s no painting, staining or varnishing required, and because aluminium doesn’t move with temperature changes, the seals and locks stay perfectly aligned. That means your home remains warm, quiet and secure – with no additional upkeep.

Efficiency that endures
Modern aluminium windows are now designed with energy efficiency built in – and SILKA’s Thermafill® technology takes that even further.
At the heart of every SILKA aluminium frame is a carbon fibre–reinforced Thermafill® core, engineered to minimise heat transfer through the structure of the window or door. It acts as an advanced insulating barrier between the inner and outer faces of the frame, helping your home stay warmer in winter and cooler in summer, while keeping energy bills under control.
This high-density core works in harmony with precision-engineered seals and premium glazing to create a complete thermal system – one that delivers real comfort without compromising on design.
You can learn more about how it works on our Thermafill® energy saving glazing page.
Sustainable by design
Aluminium is one of the most sustainable materials in construction. It’s infinitely recyclable, retaining its full quality each time it’s reused. Its longevity also means fewer replacements are needed, reducing waste and environmental impact over the lifetime of a home.
The Council for Aluminium in Building (CAB) reports that more than “75% of all aluminium produced over the last 140 years is still in active use today, being recycled more than once in many cases.” The organisation also highlights how the life expectancy of modern finishes such as anodising and high-performance powder coatings offers “unparalleled durability when it comes to weathering” – one of the many reasons aluminium is so widely specified in external building products.
At SILKA, sustainability is built into everything we do – from responsible sourcing and precision manufacturing to designing products that deliver strength and style for the long term.
So, how long do aluminium window frames last?
When designed and built to the SILKA standard, aluminium window frames can last 40 to 50 years – often twice as long as alternative materials. Their strength, stability and SILKtouch finish ensure they maintain their style and performance decade after decade.
With minimal maintenance, excellent insulation and a fine textured surface that stays beautiful for years, SILKA Aluminium Windows and Aluminium Doors are the definition of a lasting upgrade.
Because choosing aluminium isn’t just about how your home looks today – it’s about how it performs for generations to come.
