Aluminium double glazed windows are an ultra-modern, practical-yet-stylish alternative to traditional PVC or wooden frames. Long-lasting, durable and beautiful to behold, our range of windows tick every box: we even offer heritage frames to suit historic properties.
So, whether you’re looking to modernise your home or add practicality and security while maintaining its quant, era-correct aesthetic, our lineup of aluminium windows has you covered.
As with our wider range of aluminium windows and doors, all are guaranteed for 10 years for total peace of mind.
Aluminium windows have plenty of benefits. They’re stunning to look at, for starters. Because the frames are stronger, they can be thinner. This means more glass and less frame, allowing more natural light into your property and giving your home an ultra-modern appearance. The durability of aluminium frames also allows them to be slimmer and flatter, resulting in a flush fit.
Another benefit of aluminium’s durability is its resistance to both the elements and intruders. Much tougher than wood and more resilient than PVC, aluminium windows can last for years and years – they won’t rot or crack.
All of the windows we supply are available in a range of colours and finishes, so there’s certain to be one that suits your home or business premises. With either brand we supply, you can select from a handful of standard finishes or opt for a custom powder-coated finish in your choice of colour. Any shade in the RAL library is available to choose from, giving you hundreds of options!
Fitting aluminium windows to a property really can transform its appearance. Here are just a few of the installations we’ve recently completed:

A leader in its native Spain but renowned all over the world, Cortizo windows are undoubtedly among the most attractive you’ll find anywhere.
Established in 1972, the company specialises exclusively in the construction of aluminium windows and doors, giving it one focus: to produce the highest quality, most aesthetically pleasing products out there. Take one look at a Cortizo installation and it’s immediately evident that these windows are something special.
Since 1991, Senior Architectural Systems (SAS) has been on a mission to ‘revolutionise the UK’s fenestration industry.’ The company prides itself on producing top-quality, long-lasting products with outstanding thermal efficiency – and it never rests on its laurels. Continually innovating and improving upon its already world-class offering, SAS is one of the sector’s leading suppliers.
It was the first company to add a polyurethane foam thermal barrier to its aluminium windows and the first to offer powder-coated finishes with a no-quibble guarantee.
We’re located in Market Deeping, Lincolnshire, and generally serve areas within a 60-mile radius. Our installer can often be found across Cambridgeshire and Lincolnshire, but we also travel to London to complete projects on a regular basis. Our most popular locations include Peterborough, Bourne, Stamford and Huntingdon.
This very much depends on the quality of the window unit. The items we supply come from renowned brands and have met stringent quality standards, ensuring optimal thermal efficiency all year round.
No! These windows are guaranteed for a decade but should last much longer if they’re cared for; you won’t have to worry about them rusting, rotting or cracking over time.
Yes, although you will need to speak to your local authority to ask for permission beforehand: it’s up to them to decide whether or not your property can be fitted with aluminium frames.
