FAQ's

Are uPVC windows better than aluminium?

Comparing uPVC and aluminium windows for your home or garden room is not a straightforward decision - both have pros and cons. The main area’s to consider for most are:

Cost – in general uPVC flush and casement windows are less expensive than slimline aluminium windows. This is because aluminium is a more expensive material to produce requiring more manufacturing processes than uPVC.
Guarantee and Durability – both materials are extremely durable and normally have long guarantees. UPVC frames can last for up to 20 years before needing to be replaced. However, high quality aluminium windows can last even longer. In fact, they can last for 30 years or more.
Security – if you buy good quality uPVC or aluminium windows they are likely to be equally secure. It is essential that you look for products that comply with the latest PAS 24 or Document Q security standard. This standard ensures that products have been tested rigorously to achieve a pass. For extra security consider laminated security glass instead of standard toughened glazing units.
Energy efficiency – the thermal efficiency of both aluminium and uPVC windows is very similar. Before making a purchase, consider the energy rating (WER) and U-value of the windows. These values can vary depending on the glazing units fitted to them.
Aesthetics – both materials are available in a range of window designs and also colours that can match any home. While uPVC frames are slightly thicker to accommodate internal reinforcement and multi-chambered insulation, they still offer a clean, modern look. Aluminium, being a naturally stronger material, allows for slimmer frames.

As you can see picking a clear winner in the aluminium vs uPVC window debate is not straightforward at all. When making a final decision, it's important to select the material that suits your priorities and personal preference best.
