If you’re looking for a set-and-forget choice for your home, truth be told you can’t go wrong with aluminium windows.

Aluminium windows are rising in popularity across the country.
How Long Do Aluminium Windows Last?
If you’re wondering about the aluminium windows lifespan, the good news is that they’re built to last.
According to Checkatrade and industry experts, aluminium windows can last 45 years or more. That’s significantly longer than many other types of window frames.
The reason aluminium has such a long lifespan comes down to its inherent strength and weather resistance. Aluminium window frames don’t warp, crack, or swell, and they’re also immune to rust. This makes them an excellent long-term investment, giving you peace of mind that you won’t need to worry about replacing them for a generation.
Plus, modern aluminium windows come fitted with advanced thermal break technology and energy-efficient double glazing. These features not only help keep your home warm and reduce energy bills, but also increase the lifespan of the frames by preventing condensation and structural stress.

How to Achieve the Longest Lifespan for Aluminium Windows
Even though aluminium windows have an excellent reputation for durability, there are a few steps you can take to help them reach – and exceed – their expected lifespan:
Regular Cleaning
A simple clean with warm soapy water a few times a year will remove dirt, debris, and environmental contaminants that could wear down the finish over time.
Inspect the Seals
Over time, seals around window frames can degrade. Make it a habit to inspect them annually and replace any that are showing signs of wear to ensure continued energy efficiency and weather protection.
Lubricate Moving Parts
If your windows have moving mechanisms like hinges or locks, apply a silicone-based lubricant every 6–12 months to keep everything running smoothly.
Avoid Harsh Chemicals
Don’t use abrasive cleaners or solvent-based products, as these can damage the powder-coated finish on your aluminium window frames.
Professional Installation
The lifespan of aluminium windows is also closely linked to how well they’re installed. Poor installation can lead to water ingress, condensation, and unnecessary wear. At Sherborne, our professional team ensures every window is fitted perfectly to guarantee long-term performance.
Aluminium windows are known for their slim sightlines.
Factors Affecting the Durability of Aluminium Windows
Quality of Aluminium
Not all aluminium is created equal. At Sherborne, we only use premium-grade aluminium that’s built for longevity. Cheaper materials may look the same, but often lack the structural integrity and protective coatings required for UK conditions.
Powder-Coated Finishes
All our aluminium windows are finished with a durable powder coating. This improves weather resistance and prevents corrosion. With over 200 RAL colours available, it also means you can choose the exact look you want.
Glazing Type
High-performance double glazing improves thermal efficiency, reduces condensation, and prevents stress on the frame.
Aluminium is an incredibly strong metal.
Other Benefits of Aluminium Window Frames
Beyond their impressive lifespan, aluminium window frames offer a host of additional advantages that make them a smart investment for any home.
Slim Sightlines for Maximum Light
Aluminium’s inherent strength allows for thinner frames without compromising structural integrity. This means more glass, more natural light, and less visual obstruction—perfect for modern, open-plan designs.
Having a high amount of natural light in your living space is proven to come with several mental and physical benefits, including improve sleep, mood, and productivity!
Versatile Style and Colour Options
Aluminium windows are available in a wide variety of styles, from classic to contemporary. Powder-coated finishes offer a durable, fade-resistant surface in virtually any RAL colour, with dual-colour options available to suit both interior and exterior design schemes.
Strong and Secure
Thanks to their robust construction, aluminium frames provide excellent security. Most aluminium windows can easily accommodate advanced locking mechanisms and comply with PAS 24 and other increased security standards.
Environmentally Friendly
Aluminium is 100% recyclable without loss of quality. Many aluminium window manufacturers use recycled materials in their products, making aluminium a more sustainable choice compared to other materials.
