Which is better PVC or aluminium windows?

If you’re a homeowner looking for a new set of windows, you’ve probably considered whether PVC or aluminium versions are the right option for you. So to help you decide whether PVC or aluminium windows are better for your home, we’ve decided to take a closer look at each set.


PVC windows usually always comprise the more budget-friendly option. This is because aluminium is an expensive material to manufacture and this is reflected in the price of the windows.

Thermal performance

Whilst older PVC windows were regularly criticised for their poor thermal performance, modern versions have no such problem. This is thanks to energy efficient, multi-chambered profiles. Generally, they’re better insulators than aluminium windows, however aluminium variants that utilise thermally broken technology are able to insulate very well. These tend to be more expensive though.

Noise isolation

In terms of keeping external noise out of your home, PVC windows tend to do a better job than aluminium ones. This is because PVC has been designed to be a strong insulator, therefore PVC windows are ideal for those living near main roads or in noisy areas.

Residence 9 Windows and conservation areas

Residence 9 windows are constructed from uPVC, to the design specifications of old cottage windows. This means they’re regularly approved for usage in conservation areas and are the ideal choice for homes situated in these locations.


Aluminium is an incredibly durable material, resistant to corrosion and many forms of damage; it can last almost indefinitely if maintained properly. However, PVC windows tend to have a long lifespan themselves and can stay in good condition for up to 20 years. Any purchased from Emerald Home Improvements also come with a 10 year guarantee, meaning they won’t rot, peel or warp during this time.


Neither material boasts an advantage in terms of security. As long as the windows are fitted with advanced security hardware, like the windows at Emerald Home Improvements, either set will secure your home very well.


Because aluminium is incredibly strong, aluminium windows are able to feature slim sightlines and larger portions of glazing. This means they’re perfect for achieving a clean, minimalist appearance. However, this sort of aesthetic tends to be better suited to more contemporary properties and when choosing new windows, it’s important to consider a style that suits the home. PVC windows can be finished in a wide selection of finishes, allowing them to match the appearance of any style of home. This includes woodgrain effect finishes, which are ideal for achieving a classic look.

Which option is right for you, ultimately, depends on your individual preferences. However, if you’re looking for an energy efficient, cost-effective window solution that soundproofs your home, PVC windows are ideal. Interested in a set for your home?
