How do they differ from uPVC windows? If you’re new to slimline aluminium windows, they offer extra-thin frames—as thin as 20 mm. Larger glass panes also open up the views to your exterior spaces. It’s also a great way to bring more natural light into your property. Aluminium is a much stronger material that offers a lifespan of up to 45 years—10+ years longer than uPVC.
Slimline aluminium frame windows in Lincoln are a perfect match for a modern home and offer transformative effects even for older properties.
You’ll have a choice of opening mechanisms or the option to select a fixed window. With the most up-to-date locking mechanisms and a choice of handles, you’re in full control of the finished design. And that’s not to mention the vast selection of colours and finishes available, all tailored to suit your environment and design preferences. Grey and black aluminium window frames are particularly popular, but you can also opt for bolder colours or even metallic and pastel shades.

What about thermal efficiency? We provide a polyamide thermal break that offers future-proof performance for energy efficiency.
Not just for contemporary new builds, these windows are also just at home in heritage and period properties in the countryside. If anything, the thermal performance benefits will be most welcome in the exposed landscape of the Fens, which is known for getting windy.
The secure and well-insulated materials help reduce draughts and keep your property warm in winter, lowering your heating bills.
