Aluminium Windows: Pros and Cons

Table of Contents

Aluminium windows look fantastic – there is no doubt about it. Whether a property is traditional or modern, aluminium window frames are high-impact and add a touch of quality and a bucket load of kerb appeal to a home.

However, they are the lesser used material for window frames, with uPVC being the preferred option for most homeowners and developers.

We have a look at the pros and cons of aluminium windows to get to the bottom of why this might be and help you decide if they are right for you and your property.


  • Aluminium windows are extremely durable, yet lightweight and strong.
  • Aluminium windows are low maintenance, requiring no more than a wipe down from time to time.
  • Aluminium windows do not warp or rot
  • Window frames made from aluminium tend to be slimmer than PVC due to the strength of the material, allowing maximum light to enter your property.
  • They offer good insulation against heat and cold.
  • Aluminium can be recycled indefinitely without losing quality or performance, and doesn’t require a lot of energy to produce compared to PVC
  • Aluminium window frames are versatile – they come in a huge range of colours, styles and finishes and complement both modern and heritage properties.
  • Aluminium windows make an excellent alternative to the traditional, single-glazed steel windows often found on mid-century homes.


  • Traditionally, aluminium can be more vulnerable to weathering than something like uPVC. However modern Aluminium frames are weatherproof as they are coated with a marine grade paint, and can stand up to the salt water and sea air we often get along the Norfolk and Suffolk coast!
  • In terms of insulation, Aluminium is good, but uPVC can perform better. However, it may be a case of ‘slow and steady wins the race’, as while you may struggle to get the A++ rating some uPVC can offer, it will likely last longer than uPVC.
  • Cost. Aluminium frames, compared with uPVC, are typically more expensive, but in terms of durability and finish, you get what you pay for. It is also less expensive than other alternatives such as steel.
