Choosing new windows for your home is a significant investment, and most homeowners now find themselves stuck in deciding between two materials: uPVC or aluminium windows.
In this comprehensive guide, we’ll break down the key differences between these two popular window materials, comparing them across several factors that matter most to homeowners:
- Energy efficiency
- Style options and aesthetic appeal
- Durability and expected lifespan of each material
- Maintenance requirements
- Weather resistance
- Value for money
By examining each of these aspects in detail, we’ll help you understand the main benefits of uPVC and aluminium windows, allowing you to decide which material best suits your needs.
Energy Efficiency
uPVC Windows
uPVC frames are naturally insulating and feature multiple chambers within their design that trap air, providing excellent thermal efficiency. Our uPVC windows achieve outstanding energy ratings thanks to their innovative design, helping to reduce energy bills and keep your home warmer. The material acts as a natural insulator, meaning less energy is lost through the window frames.
Aluminium Windows
Aluminium has a reputation for poor thermal performance, but this is now untrue. Modern aluminium window frames incorporate thermal break technology that significantly improves their energy performance. Today’s versions feature excellent insulation that helps maintain indoor temperatures. At Windows & Doors 2 You, our aluminium windows can attain A+ energy ratings.
Who Wins?
When it comes to pure energy efficiency, uPVC has a slight edge. The natural insulating properties of uPVC combined with multi-chambered profiles and double glazing allow it to achieve low U-values (a number that measures how well a window keeps heat inside your home – the lower the number, the better.)
Despite this, aluminium windows have come a long way and, with high quality glazing and thermal breaks, can match the energy efficiency of uPVC windows.
Style and Aesthetics
uPVC Windows
UPVC windows have improved from their historically white, utilitarian design. They are now available in a wide range of colours and finishes, including convincing woodgrain effects. This is most notable in the popular Residence Collection, uPVC windows that are designed to replicate timber windows without the maintenance hassle that wood plagues homeowners with.
From classic casement windows to flush sash windows, the variety of styles available means you can achieve almost any look. Perfect for both period properties and modern homes, uPVC offers versatility in design.
Aluminium Windows
Aluminium frames are renowned for their slim sightlines and modern appearance. They are particularly popular in contemporary and new build homes. The strength of aluminium allows for larger glass areas and thinner frames, which can create great views and flood homes with natural light. Modern aluminium windows aren’t just restricted to modern properties. They are also being used more frequently in renovation projects for traditional properties.
Who Wins?
This largely depends on your property type and personal preference. For modern homes seeking minimalist aesthetics, aluminium windows are often the best window solution. For traditional properties or those seeking a more classic look, uPVC is a great option.
Durability
uPVC Windows
UPVC is a highly durable material that offers a long lifespan of 20-30 years when properly maintained. Unlike traditional timber windows, uPVC frames won’t warp, rot, rust, corrode or become misshapen over time, ensuring your windows continue to operate smoothly for decades.
This stability also means they maintain their weatherproofing properties and security levels throughout their lifetime.
Aluminium Windows
Aluminium frames are exceptionally strong and can last 30-40 years or more. As a highly durable material, aluminium resists corrosion and maintains its structural integrity well over time. The inherent strength of aluminium allows for larger glass panels and slimmer frames without compromising on stability, making it particularly suitable for larger window installations.
Who Wins?
Aluminium takes this category due to its superior strength and longer potential lifespan. However, both materials are more durable than traditional timber windows and can serve your home for multiple decades.
Maintenance
uPVC Windows
One of the main benefits of uPVC windows is their low maintenance requirements. They never need painting or staining, and simple cleaning keeps them looking fresh. This makes them an excellent choice for busy homeowners who want to spend less time on property maintenance. The frames won’t peel, blister, or require sanding like timber windows.
Regular maintenance is as simple as cleaning the frames a few times a year and ensuring the drainage holes remain clear of debris. Beyond this, uPVC windows are virtually maintenance-free.
Aluminium Windows
Similar to uPVC, aluminium frames are also low maintenance. They require minimal upkeep beyond regular cleaning and occasional checks of the hardware. The powder-coated finish is highly durable and resistant to fading. Unlike traditional metal windows of the past, modern aluminium frames won’t oxidise or deteriorate when exposed to the elements.
Who Wins?
It’s a tie – both materials excel in this category, offering significantly less maintenance than timber windows.
Price
uPVC Windows
uPVC is more affordable than aluminium due to lower manufacturing costs, and it offers excellent value for money. They’re often popular for homeowners working with a specific budget while still wanting quality windows.
When factoring that uPVC double glazed windows can reduce energy bills, they are one of the most cost-effective home improvements a homeowner can make.
Aluminium Windows
Typically more expensive than uPVC, aluminium windows represent a premium product, with prices often 30-50% higher than comparable uPVC options. However, despite the higher initial cost, their long lifespan, minimal maintenance requirements, and ability to add value to your property can make them a cost-effective long-term investment.
Who Wins?
UPVC windows beat aluminium on initial cost. Despite this, aluminium’s longevity and ability to increase property value can make it competitive across the lifetime of both products.
Why Would You Choose Aluminium?
Aluminium windows are the perfect choice if you’re looking for a modern style with minimal sightlines and maximum glass area. They’re ideal for contemporary homes or architectural projects where style is important, and their exceptional durability makes them perfect for larger installations.
While they require a larger initial investment, their longer lifespan and appearance make them worth considering if your budget allows it.
We offer two ranges of aluminium windows – our classic range and our prestige range.
