Demand for aluminium windows has been rising steadily, and for good reason. They offer durability, sleek aesthetics, and excellent energy efficiency. But how do they compare to uPVC windows, a long-standing favourite in the market? In this guide, we’ll explore the benefits of both, helping trade installers and homeowners make informed decisions.

Benefits of uPVC Windows
Durability and Weather Resistance
uPVC windows are extremely robust and built to withstand harsh weather conditions, including wind, rain, and hail. Their strength and construction ensures long-lasting performance, making them a reliable choice for many homeowners.
Energy Efficiency
With double glazing as standard, uPVC windows help maintain a comfortable indoor temperature year-round. They trap warm air inside during winter and keep heat out during summer, helping your customers save on energy bills while reducing their environmental impact.
Low Maintenance
One of the most appealing aspects of uPVC windows is how easy they are to maintain. A simple wipe with soapy water and a damp cloth keeps them looking pristine — no need for painting or special treatments.
Design Flexibility
uPVC windows come in a wide variety of colours, finishes, and styles, allowing homeowners to match their windows to their décor. Additionally, they provide excellent sound insulation, making them ideal for properties in noisy areas.

Benefits of Aluminium Windows
Strength and Longevity
Aluminium windows are stronger and more robust than uPVC, offering exceptional durability without rusting or discolouring. They are built to last, even in challenging weather conditions.
Energy Efficiency
Our Sheerline windows feature Thermlock technology, this innovative multi-chamber design is hidden away inside the windows. The closed-cell insultating chambers act as a thermal break and work in conjunction with the glazing to create class leading thermal performance. This improves comfort within the home and reduces energy bills.
Security
The construction of our aluminium windows, multi-point locking, quality hardware and additional features such as hinge protectors help to create exceptional levels of security. For added peace of mind, upgrading to laminate glass offers extra protection.
Aesthetic Appeal and Natural Light
Aluminium windows offer slim, stylish frames that maximise natural light. They are available in a wide range of colours, making them suitable for both modern and classic properties.
Flexibility for Feature Windows
Another advantage of aluminium windows is their ability to accommodate larger-scale and uniquely shaped “feature” windows. The strength of aluminium frames allows for expansive glass panels without compromising structural integrity, making them ideal for creating striking visual impact and modern architectural designs. Curved, angled, or floor-to-ceiling windows are all achievable, giving homeowners the flexibility to make a bold statement while still benefiting from excellent insulation, security, and durability.
Which Should You Choose?
Both uPVC and aluminium windows offer unique advantages. uPVC is durable, low-maintenance, and cost-effective, while aluminium offers superior strength, greater flexibility, security, and sleek aesthetics.
