Choosing the Right Windows for Your Property
If you’re planning to replace your windows, the choice between aluminium and uPVC is one of the most important decisions you’ll make. Both materials have their strengths, but which is better suited to Sussex’s varied climate — from salty coastal air in Shoreham and Worthing, to the cooler, windier hills around Horsham and Crawley?
In this guide, we’ll break down the key differences between aluminium and uPVC windows, and help you decide which one is the better fit for your home.
Weather Resistance and Durability
uPVC Windows
uPVC is a popular option for homes across West Sussex due to its affordability and low maintenance. It’s resistant to rot, doesn’t require painting, and handles most British weather well. However, over time, prolonged exposure to UV light and coastal air can cause discolouration and brittleness in lower-quality frames.
Aluminium Windows
Aluminium is highly durable, even in tough weather conditions. It doesn’t warp, swell, or fade, and is particularly well-suited for exposed or coastal locations. With powder-coated finishes, aluminium frames remain stable and sharp-looking for decades — making them ideal for homes near the coast or open countryside.

Thermal Efficiency and Insulation
uPVC has long been considered the go-to for insulation. It naturally resists heat transfer, making it effective in preventing warmth escaping your home in winter.
Aluminium, traditionally seen as less thermally efficient, has seen huge improvements in recent years. Today’s frames come with a built-in thermal break — a non-metallic section that stops heat passing through the frame. Combined with high-quality glazing, modern aluminium windows can now match or exceed uPVC for thermal performance.

Aesthetic Appeal and Design Options
One of aluminium’s key strengths is design flexibility. The material allows for slimmer frames, sharper lines, and larger panes of glass — perfect for modern and architecturally-led homes in places like Haywards Heath or East Grinstead.
uPVC has improved a lot in recent years too, with woodgrain finishes and colour options like Colourtek.
However, aluminium still leads when it comes to achieving that high-end, contemporary look.
Cost Considerations
uPVC remains the more budget-friendly option, often costing significantly less than aluminium. For standard residential homes or rental properties, it’s often the practical choice.
Aluminium is more of an investment — but one that can pay off in both lifespan and added kerb appeal, particularly in premium properties or self-build projects.
Which Is Right for You?
Choose uPVC if:
- You’re working to a tighter budget
- You want reliable thermal efficiency with minimal cost
- Your home is more traditional or you’re replacing like-for-like
Choose Aluminium if:
- You’re aiming for a sleek, modern design
- You live in an exposed or coastal area
- You want longevity, low maintenance, and high visual impact
